Important facts about thread and needles

032907.52.04_0910_a430/a440/a450_EN

Important facts about thread and needle

With the right combination of thread and needle optimum sewing results are achieved. The following are the guidelines: replace needle when starting a new sewing project.

Thread

The thread is chosen according to use. For a perfect sewing result, thread and material quality play an important role. It is recommended to use quality brand threads.

Cotton thread

• cotton threads are particularly suitable for cotton fabrics

• mercerized cotton threads have a slight sheen

Polyester thread

• polyester thread is suitable for practically all sewing needs

• it has a high tensile strength and is particularly colorfast

• polyester thread is more flexible and is recommended where a

strong and elastic seam is required

Guidelines Needle No.

fine fabrics: fine thread (darning thread,

embroidery thread) 70–75

mediumweight fabrics: normal thread 80–90

heavyweight fabrics: heavier thread 100, 110, 120

Needle, thread and fabric

The correct needle size depends on the selected thread and fabric. Fabric type and structure determine which thread weight, needle size and needle tip should be used.

Needle summary

BERNINA requires needle system 130/705 H. This system number refers to shank shape as well as to length and form of the needle point.

Checking the needle condition

The needle condition should be checked and the needle replaced regularly. A defective needle not only damages the fabric but also the sewing computer.

130 / 705 H S 70

Shank diameter = 0.7 mm (needle size)

Needle point e.g. medium ball point

Needle scarf

Flat shank

Shank length

Needle/thread combination

In order to check the needle/thread compatibility, the correct size thread must correspond with the correct size needle.

Correct needle/thread combination

When sewing, the thread should travel smoothly down the long groove on the front of the needle.

Too thin thread or too thick needle

The sewing thread has too much play in the groove. This could lead to skipped stitches and damage to the thread.

Too thick thread or too fine needle

The thread rubs on the edges of the groove and can get jammed. This can break the thread.

Feed dog and fabric feed

Let the fabric feed evenly.

Feed dog and stitch length

With each stitch the feed dog moves forward by one step. The length of this step is determined by the stitch length selected.

Pulling, pushing or holding back the fabric will result in uneven stitches.

With an extremely short stitch length, the steps are also very short. The fabric moves under the foot quite slow ly, even at full sewing speed.

Buttonholes, satin stitch and de co rative stitches are all sewn with a very short stitch length.

Feed dog and fabric feed with height compensating tool

The feed dog works accurately when the foot is level.

Uneven layers To solve this problem, place one, two or three compensating plates as required behind the needle under the presser foot to level it.

If the foot is at an angle, e.g. when sewing over thick to thin or vice-versa, the feed dog cannot grip and feed the fabric and the fabric might jam.

To correct the height in front of the foot, place one or more plates to the right of the foot close to the needle. Sew until the foot is level again and remove the plates.

Feed dog and sewing corners

The space between the two rows of the feed dog is relatively large due to the width of the stitch plate hole.

Place one or more plates as close as possible to the edge of the fabric on the right side of the presser foot. This allows for better feeding of the fabric when sewing corners.

Presser foot pressure and Balance

032907.52.04_0910_a430/a440/a450_EN

Presser foot pressure

Dial on head frame

• the pressure is adjusted at the left side of the head frame

Standard pressure

• for normal sewing work

• default = 47

• the default setting is always visible, it

blinks

Increased pressure

• for firm fabrics

• improves fabric feed

Balance

Different fabrics, threads, stabilizers and interfacings can affect programmed stitches so, that sometimes they might not join or might overlap, i.e. the stitches that make up the pattern are too close together or too far apart. These effects can be corrected with the Balance so that the stitch formation can be adjusted where necessary to suit the fabric.

Balance for practical and decorative stitches

When sewing soft fabrics such as jersey or tricot, the fabric tends to stretch under the presser foot which also stretches the stitch being sewn. For example, the Honeycomb stitch opens up and is too long. Thicker fabrics might cause the stitch to overlap, making it too short. Correcting with the Balance is very easy. Test-sew first!

Reduced pressure

• for jerseys and loose knits

• to prevent fabric from stretching

• adjust pressure so that the fabric still

feeds correctly

Do not forget to reset the balance by pressing the

balance or clr button after sewing with adjusted balance values.

Stitch formation too long Stitch formation too close Desired stitch formation

• press the Balance button

• press the left Needle position button =

shorter stitch length (maximum 9 steps)

• press the Balance button

• press the right Needle position button =

longer stitch length (maximum 9 steps)

Patchwork foot

Accuracy is essential when sewing patches together. The side edges of the Patchwork foot are exactly 1/4” (6mm) from the center needle position. The center indents on either side of the foot indicate the needle insertion point and the two additional indents marking 1/4” (6mm) in front of and behind the needle. When you sew at a foot’s width, the seam allowances will always be of the exact width and it is easy to turn the work while maintaining the

same width. Piecing patchwork is sewn with a straight stitch. A stitch length of

1.5-2mm is ideal. It is not necessary to secure the stitches for these relatively short seam lengths.

Attach the slide-on table for precise and easier work.

BSR foot - Application

Stitch: Needle: Thread:

Feed dog:

Presser foot:

Straight stitch No. 1 size and type suitable for the fabric selected monofilament or cotton down BSR foot No. 42

BSR (BERNINA Stitch Regulator) function

This function using the BSR presser foot allows for free-motion quilting (sewing) using the straight stitch and a pre-selected stitch length (up to 4mm). The BSR presser foot reacts to the movement of the fabric under the foot and controls the speed of the sewing computer up to the maximum possible speed. The following applies: the faster the fabric is moved the higher the speed of the sewing computer. A regulated set stitch length is maintained within a certain speed, independent of the movement of the fabric. If the fabric is moved too fast an acoustic signal is heard, provided the beeper function has been previously activated. (see page 46).

By activating the BSR function the sewing computer sews either continuously at a reduced motor speed (mode 1, standard) or on moving the fabric (mode 2). As long as the BSR presser foot is illuminated red, adjustments like threading and changing the needle, for example must not be carried out. The sewing computer is still in BSR mode and the needle will engage while fabric is moved unintentionally! Without fabric feed the BSR mode is turned off after approx. 7 seconds and the red light goes off. Please refer to the Safety Instructions!

BSR function can be sewn in 2 separate modes of operation

• BSR mode 1 is the active standard

• on pressing the foot control or the

Start-/Stop button, the needle starts to move continuously

• moving the fabric under the foot will

engage the sewing computer to accelerate

• through the continuous needle movement securing in the same position is possible without pressing an additional button

For an even sewing start (one single stitch) the foot control must be

pressed and the fabric moved simultaneously. This also applies for sewing points and straight stitching within a round form.

• press external button No. 2 of the stitch

selection (see page 29) to engage BSR mode 2

• the sewing computer only starts if the

foot control or Start-/Stop button is pressed and the fabric moved simultaneously

• the movement of the fabric determines

the sewing speed

• for securing, the «Securing function»

button must be pressed

• press external button No. 1 of the stitch

selection to engage BSR mode 1

When resuming work with the BSR presser foot after exiting the function, the BSR mode that was active at the time of exiting the BSR function will be activated, even if the sewing computer was turned off in the meantime.

Buttonholes - Important information

aurora 430 / 440 QE

Thread tension

• thread the bobbin thread through the finger of the bobbin case

= the bobbin tension is a little tighter

• this gives the beads on the right side of the fabric a slightly

rounded appearance

• the buttonhole looks more attractive

• gimp reinforces buttonholes and enhances their appearance

• sew both beads at the same speed

Marking buttonhole

Manual buttonhole

• mark the buttonhole length in the

desired position

• use Buttonhole foot No. 3C, 3 (optional

accessory)

Automatic buttonhole

• mark the length of just one buttonhole

• after sewing the first buttonhole, the

length for all subsequent buttonholes is automatically programmed

• mark only the beginning of all subsequent buttonholes

• use Automatic buttonhole foot No. 3A

aurora 450

Thread tension

• set upper thread tension to 2.5 (Buttonhole symbol)

• the bobbin tension is a little tighter which gives the beads on

the right side of the fabric a slightly rounded appearance

• the buttonhole looks more attractive

• gimp reinforces buttonholes and enhances their appearance

• sew both beads at the same speed

Using the compensation plate (in some countries only available as optional accessory) is recommended when sewing buttonholes in difficult fabrics. It can be used with the Automatic buttonhole foot No. 3A or the buttonhole foot No. 3B.

Keyhole buttonhole

• mark the bead length only

• the correct length eye will be added

when the buttonhole is sewn

Test sewing

• always sew a test sample on the fabric

with stabilizer you intend to use

• select the buttonhole type you intend to

use

• sew the buttonhole in the same

direction on the fabric (with or against the grain)

• cut the buttonhole open

• push the button through

• adjust the buttonhole length if

necessary

Bulky buttons

• with bulky buttons (roll crown, bulge-

rimmed etc.) add approx. 3-5mm to the buttonhole length (depending on the size and bulk of the button)

To adjust the bead width:

• alter the stitch width

Stitch length adjustments:

• Stitch length adjustments affect both

buttonhole beads (spacing between the stitches)

• reprogram the buttonhole length after

changing the stitch length

If a buttonhole is to be sewn at right angles to a seam, we recommend the use of the height compensating plates for buttonholes (available as optional accessory). Place the plates from the back between fabric and bottom of slide foot up to the thick part of the fabric and push to front.

Embroidery stabilizers

When using paper backed adhesive stabilizer make sure that there is no adhesive residue on needle, stitch plate and hook area.

Tear-away stabilizers

• similar to interfacing; tears like paper

• one or more layers can be used

• available in different weights

• for more stability, apply to the wrong side

of the fabric with temporary spray adhesive before hooping

• carefully tear away excess stabilizer from

the back of the embroidery after stitching

• stabilizer will remain under larger

embroidered areas

Application:

• for all wovens and non-stretchables

Iron-on interfacing

• must be preshrunk by soaking in warm

water

• this is pressed (fused) to the wrong side

of the fabric

• iron-on interfacings are available in a

variety of weights and should be selected to suit the fabric being used

• removable iron-on interfacing is also

available

Application:

• to provide body and shape for fabrics

onto which motifs will be placed

• use in conjunction with appropriate

stabilizer

Cut-away stabilizers

• one or more layers can be used

• available in light- and heavyweight

• for more stability, apply to the wrong

side of the fabric with temporary spray adhesive before hooping

• carefully cut away from the back of the embroidery after stitching

• stabilizer will remain under larger

embroidered areas

Application:

• for all stretchable fabrics

Paper backed adhesive stabilizer

• place stabilizer in hoop, paper side up

• use a pointed object (e.g. scissors) to

score the paper and remove it to reveal the self-adhesive surface

• position the piece of fabric to be embroidered on the stabilizer

Application:

• intended for delicate fabrics such as

jersey or silk, or hard to hoop fabrics such as velvets

• for pieces, sections and materials that

can not be hooped

Spray adhesive

• do not use spray adhesive near or

directly at embroidery computer

• use spray to stick stabilizer to wrong

side of fabric for more stability

• sparingly use spray adhesive and spray

form a distance of 25-30cm to stabilizer

• place fabric and sprayed stabilizer flat

on each other and press together

Application:

• on stretchable fabrics and knits to

prevent distortion

• appliqué: exact securing of appliqués for

embroidery

• smooth fabrics: to prevent shifting

• cutwork: to fix cut-out pieces on stabili-

zers, e. g. pockets on trousers, collars etc.

• for fabrics that easily crush or otherwise

be marked by hooping: use spray adhesive on the stabilizer, hoop the stabilizer, then fix the sections to be embroidered onto the stabilizer

Spray starch for additional stiffening

• spray starch is ideal for stiffening fine,

soft or loosely woven fabrics

• spray the area to be embroidered, let

dry or press gently with a warm iron

• always use an additional stabilizer such

as water soluble stabilizer on the wrong side of the fabric

Application:

• ideal for fine, loosely woven fabrics, e.g.

batiste, fine linen, etc.

Page 67

Water soluble stabilizer for fabric with a

032907.52.04_0910_a430/a440/a450_EN

pile and lace embroidery

• water soluble stabilizer looks like plastic

wrap

• dissolve stabilizer in warm water when

embroidery is complete

• water soluble stabilizers are ideal

protection for fabrics with a thick or looped pile such as toweling. It also prevents the embroidery threads from sinking into the fabric or the fabric threads from poking out between the stitching

• place on top of toweling and high nap

fabrics backed by appropriate stabilizer for fabric and motif

• use spray adhesive to fix stabilizer if

necessary

• for fabric with a pile, reinforce with

additional, suitable stabilizer on the wrong side if necessary

Important embroidery information

• for lace embroidery place one or two

layers of water soluble stabilizer in hoop (as the motif is not embroidered on any fabric, only the thread embroidered motif is left)

• after dissolving lay the motif down flat

and let dry

• water soluble stabilizer can also be

removed by gently tearing it away when used as a topping on non-washable fabrics like velvet

Application:

• ideal for toweling, velvet, bouclé knits,

etc.

• ideal for fine, sheer fabrics such as

organdy, batiste, etc.

• recommended for use as a stabilizer

with low stitch count motifs

• use heavier water soluble stabilizer to

stitch lace motifs

Important embroidery information

Choosing an embroidery motif

• simple motifs with a low stitch count are

suitable for embroidery on fine fabric

• large-scale, densely embroidered motifs (e.g. with multiple color and embroidery direction changes) are suitable for medium- and heavyweight fabrics

Embroidery test

• always stitch an embroidery test on a

sample fabric. Adjust color, thread quality, needle, stitch density, tension, etc. to suit the motif if necessary

• for the test use the same fabric and

stabilizer that you will use on the project

Scaling/Sizing motifs

• motifs can be scaled/sized with the BERNINA embroidery software on the PC

• extensive scaling up or down of motifs

may lead to unsatisfactory results

Page 68

Important embroidery information

032907.52.04_0910_a430/a440/a450_EN

Different stitch types

Underlay stitches

• underlay stitches are the foundation of a

motif and are used to stabilize the base fabric and hold it in shape. They also prevent the covering stitches of the motif from sinking into the knit or the nap of the fabric

Satin stitch

• the needle moves left to right and

viceversa. The result is a very dense, covering zig-zag stitching to fill the shape

• satin stitching fills are ideal for narrow

and small shapes. Satin stitching is, however, not suitable for larger areas, since wide stitches are too loose and do not cover the fabric properly. In addition there is the danger that with too long stitches the threads could catch on something which would damage the embroidery

Step stitch

• a fill stitch with stitches of specified

length sewn in rows used primarily to fill large areas quickly

Fancy-fill stitches

• to give areas a special effect

• stitches that create a motif with an area

to be filled

Outline stitches

• usually straight or satin stitches

• used to define a specific area or areas

• examples are: straight stitch, double run,

triple run, satin

Jump stitches

• long stitches that skip over fabric after

one part of the motif finishes and the next begins

• before and after the jump stitch securing

stitches are sewn

• jump stitches are trimmed before the

next color starts to embroider

Embroidery threads

032907.52.04_0910_a430/a440/a450_EN

Important embroidery information

One of the most important elements in successful embroidery is the quality of the thread. We strongly recommend that you purchase thread from a reputable BERNINA dealer in order to avoid irregularities, thread breakage, etc. which so often occur with poor quality threads.

Embroidery is particularly effective if you use glossy rayon or polyester embroidery threads as upper threads. They are available in a wide range of colors for beautiful embroidery.

Polyester threads

Polyester with a brilliant sheen is a hard wearing colorfast thread and has a high tensile strength. It is suitable for all types of embroidery, especially children’s clothing and items which will be washed often or subject to much wear and tear.

Rayon threads

Rayon is a soft viscose fiber with a brilliant sheen and suitable for fine, delicate embroidery, or items that will not receive excessive wear and tear.

Metallic wrapped polyester thread

Metallic thread is a light- to mediumweight thread suitable for special effects in embroidery.

Embroidery needle

• correct size thread must correspond with

correct size needle

• replace needle regularly

When sewing with metallic threads, we recommend the

use of the vertical spool pin and the supplementary thread guide (optional accessory).

It is recommended to use a 130/705H Metafil needle and to reduce the speed.

Bobbin threads

Bobbin-Fil (special bobbin thread)

Bobbin-Fil is an especially soft and light polyester thread suitable for bobbin thread. This special bobbin thread ensures a steady thread tension and an optimal intertwining of the upper and bobbin thread. The thread produces even stitching on both, the right and wrong side of the fabric.

Darning and embroidery thread

Fine mercerized cotton thread suitable for embroidery (Mettler 60 weight suggested), which is embroidered on cotton fabric.

Use white bobbin thread or match color with fabric.

Requirements / Embroidery software

Requirements for embroidery operations

BERNINA applies the widely used USB technology to their Sewing/Embroidery systems. In order to avoid undesirable interaction between BERNINA’s individual USB devices and other USB devices, BERNINA recommends taking the following precautions:

• Avoid turning the aurora Sewing/

Embroidery System or other USB devices on and off in short intervals.

• When using an embroidery software

with dongle, do not unplug the dongle while the software is running!

• During the embroidery stitch out

process, do not unplug the USB cable.

• Before turning off the aurora Sewing/

Embroidery System, always close the embroidery software and then unplug the USB cable.

• If you intend to use a USB HUB device

or other USB devices, BERNINA recommends using the USB Standard of Version 2.

• BERNINA recommends closing all

running computer programs while embroidering wiht the embroidery software / EC on PC programs.

System requirements of your PC

Minimum requirements

Pentium 3 CPU, 800 MHz or higher Windows XP Prof. and Home Service Pack 2 256MB RAM, 2 USB ports, 500MB available space 8GB Hard Disk Memory, 16 Bit True Color Graphic Card

Recommended requirements

Pentium 4 CPU, or higher Windows XP Prof. and Home Service Pack 2 Windows Vista 512 MB RAM or higher, 2 USB ports, 20GB Hard Disk Memory, 750MB available space, 32GB or higher True Color Graphic Card

The «aurora» embroidery system is operated by the BERNINA embroidery software PC embroidery software and directly on the personal computer by the EC on PC software.*

When the aurora Sewing/ Embroidery System is in the embroidery mode, the foot control must be unplugged.

To avoid errors with embroidery via personal computer no virus scanner must be activated.

If the aurora 430 / 440 QE / 450 is connected to the computer via a USB hub, the system can cause difficulties when turning off the aurora 430 / 440 QE / 450 with running embroidery software (depending on the PC configuration). These difficulties are easily remedied by rebooting the PC. Stitching in the already started motif can be resumed at the last stitch with the function «Embroidery sequence control» and «Saved embroidery position» (see page 76).

* the term PC basically applies to PC and laptop

BERNINA embroidery software

The software is necessary to open and edit (rotate, scale etc.) embroidery designs. Refer to enclosed CD-ROM for user instructions.
