1.Description of product

1.1 Description of proper use

The 1281/5 is a sewing unit which can properly be used for sewing light to medium-weight material. Such material is, as a rule, made of textile fibres. These materials are used in the garment industry.

In general only dry material must be sewn on this machine. The material must not contain any hard objects.

The seam is generally made with core thread, polyester fibre or cotton threads.

The dimensions for needle and hook threads can be taken from the table in chapter 4.2.

Before using any other threads it is necessary to estimate the consequential dangers and to take the respective safety measures, if required.

This sewing unit must only be installed and operated in dry and well-kept rooms. If the sewing unit is used in other rooms, which are not dry and well-kept, further measures to be agreed upon may become necessary (see EN 60204-31 : 1999).

We, as a manufacturer of industrial sewing machines, assume that at	1
least semi-skilled operating personnel will be working on our products

so that all usual operations and, where applicable, their risks are presumed to be known.

1.2 Brief description

The Beisler 1281/5 is a sewing unit for closing long seams, as e.g.

trousers side seams and crotch seams,

side seams without vent in upper fabric and lining in skirt parts.

According to the machine head it is possible to sew

double-chainstitch seams (401),

4-thread safety seams (515) or 5-thread safety seams (516).

All sewing station components are mounted on a stand welded of square steel tubes and controlled by a microprocessor system.

The sewing station is operated via a control panel. Here it is possible to call up various control programs, to define new programs and to check all inlets and outlets for maintenance and repair purposes.

–Narrow sewing tools incl. narrow sewing foot for trouble-free guiding / sewing of the pocket openings

–Automatic contour modulation by programmable puller

–Height-adjustable stand, infinitely variable from 850 mm to 1200 mm

–Automatic fullness distribution by step motor-controlled needle and bottom feed (optional). Within a seam program the fullness of the needle and bottom feed can be programmed at the control panel via 3 freely selectable lines. User-friendly adjusting possibility of the fullness in one line via each one controller.

–Integrated stacking device

–Manual stacking via shortcut key

For an immediate stop in case of operating errors, needle breakage etc. the safety system of the 1281/5 provides the following measures:

–Press program stop switch 2 at the control panel. The running operations are stopped immediately.

–Turn main switch 1 counter-clockwise. The sewing unit drops out immediately;

all movements of the sewing unit stop immediately.

3.4Restart after program stop

Caution: Risk of injury!

Switch the main switch off.

Clear the fault only with the sewing unit switched off.

Only restart the sewing unit after the fault has been cleared.

–Switch on main switch 1 (turn in clockwise direction).

–Unlock the program stop switch.

The control loads the machine program.

The basic display appears in the display of the control panel. The sewing unit is ready for operation again.

4.Operation of the sewing machine head

4.1 General notes

The operation of the sewing machine head (needle insertion, threading of needle thread and hook thread etc.) is described in the attached separate Pegasus operating instructions.

The instruction manual is included in the accessories of the sewing unit.

Attention: Risk of injury!

Please read the operating instructions of the sewing machine head carefully and observe all notes on safety.

4.2Recommended threads

Needle system:	B27
Recommended
needle size:	Nm 80 for very thin material
	Nm 90 for thin material
	Nm 100 for medium-weight material

High sewing security and good sewability are achieved with the following core threads:

–Two-ply polyester endless polyester core-spun (e.g. Epic Poly-Poly, Rasant x, Saba C, ...)

–Two-ply polyester endless cotton core-spun (e.g. Frikka, Koban, Rasant, ...)

		If these threads are not available, the polyester fibre or cotton threads
		listed in the table can also be sewn.
		Often two-ply core threads are offered by the thread manufacturers
		with the same designation as three-ply polyester fibre threads
		(3cyl.-spun).This causes uncertainty with regard to twisting and thread
		thickness.					1
		When in doubt, unravel the thread and check whether it is twisted 2- or
		3-ply.
		The label no. 120 on the thread reel of a core thread corresponds e.g.
		to the thread size Nm 80/2 (see table values in brackets).
		In case of monofilament threads you can use needle threads and hook
		threads of the same thickness. The best results are achieved with soft
		and elastic threads (software) of the thread thickness 130 Denier.
		Recommended thread thicknesses:
Needle size		Core thread		Core thread
Nm
	Needle thread		Hook thread	Needle thread	Hook thread
	Polyester		Polyester	Polyester	Cotton
	endless		core-spun	endless	core-spun
	Label No.		Label No.	Label No.	Label No.

The mouse is used for clamping the trousers and skirt parts to avoid their sliding away.

The guide rail 3 is flexible and adaptable to the contour of the workpiece.

Caution: Risk of injury !

Do not reach into the open mouse.

Inserting the workpiece

–Place the workpiece between mouse plate 2 and clamping arm 1.

–Close the mouse.

During the sewing process the mouse is drawn along the guide rail 3 until the opening of the clamping arm 1 is released by a limit switch.

Then the mouse is pulled back by the return mechanism 4 until the adjustable stop 5 is touched.

5.3 Feeding the workpieces and starting the sewing process

The sewing unit for closing seams 1281/5 works semi-automatically at high speed.

The operator of the sewing unit has to do the following:

call up the desired seam program;

feed and align the workpiece precisely;

sew the first seam section manually;

start the automatic sewing process;

supervise the sewing process of the unit;

remove the finished parts from the stacker.
