2. Designated use
GB
The 867 is a s ewing machine designed for sewing light to
medium-heavy material. Such material is generally made of textile
fibres, but it may also be leather. It is used in the clothing industry and
for domestic and motor-vehicle upholstery.
This special sewing machine can also be used to produce so-called
technical seams. In this case, however, the operator must assess the
possible dangers which may arise (with which DÜRKOPP ADLER AG
would be happy to assist), since such applications are on the one hand
relatively unusual and, on the other, so varied that no single set of
criteria can cover them all. The outcome of this assessment may
require appropriate safety measures to be taken.
Generally only dry material may be sewn with this machine. The
material may be no thicker than 10 mm when compressed by the
lowered sewing feet. The material may not contain any hard objects,
since if it does the machine may not be operated without an
eye-protection device. No such device is currently available.
The seam is generally produced with textile-fibre sewing thread of
gauge up to 11/3 NeB (cotton), 11/3 Nm (synthetic) or 11/4 Nm
(covering yarn).
Before using any other thread the possible dangers arising must be
assessed and appropriate safety measures taken if necessary.

3. Subclasses
This special sewing machine may be set up and operated only
in dry, well-maintained premises. If the sewing machine is used in
premises which are not dry and well-maintained it may be
necessary to take further precautions (which should be agreed in
advance - see EN 60204-31:1999).
As manufacturers of industrial sewing machines we proceed on the
assumption that personnel who work on our products will have
received training at least sufficient to acquaint them with all normal
operations and with any hazards which these may involve.

6.2 Adjusting the needle-thread tension
Pre-tensioner
When the main tensioner 2 and supplementary tensioner 3 are open
(e.g. when the sewing feet are raised) the needle thread must be
under slight residual tension. This residual tension is produced by the
pre-tensioner 1.
The pre-tensioner 1 simultaneously affects the length of the end of the
severed needle thread (the starting thread for the next seam).
–
Basic setting:
Turn knurled nut 4 until its front is flush with the bolt 5.
–
To shorten the starting thread:
Turn knurled nut 4 clockwise.
–
To lengthen the starting thread:
Turn knurled nut 4 anticlockwise.
Main tensioner
The main tensioner 2 should be set to the minimum possible tension.
The looping of the threads must be in the center of the material.
With thin material excessive thread tension can cause unwanted
gathering and thread breakage.
–
Adjust the main tensioner 2 so that the stitches are uniform.
To increase tension - turn the knurled nut clockwise
To decrease tension - turn the knurled nut anti-clockwise
Supplementary tensioner
The supplementary tensioner 3 can be switched in to effect a rapid
change in needle-thread tension during operation (e.g. with thickened
seams).
–
Set the supplementary tensioner 3 lower than the main tensioner 2.
6.2.1 Adjusting the needle-thread tension on automotive machines
On automotive machines, it is possible to secure the main tensioner 2
and the supplementary tensioner 3 against altering through the user.
Adjusting the thread tension
–
Loosen the screw 6 and remove the interlock mechanism 7.
–
Adjust the needle-thread tension according to the description given
under chapter 6.2.
–
Put on the interlock mechanism 7 again and secure it by fastening
the screw 6.

6.2.2 Function of the thread main tension and the thread supplementary tension in relation to the sewing
foot lifting
The thread supplementary tension can, at any time, be switched on or
off by actuating key 1 (see chapter 6.16) of the key pad. To this end,
the parameter F-255 must be set on “7".

If the thread’ s supplementary tension is opened, this condition will
·
be maintained when lifting the sewing foot.
When switching the machine off, the last setting of the thread’s
·
supplementary tension will be maintained through the mains
connection.
6.2.3 Reparation seam with thread tension always closed
When executing a reparation seam, the thread tension is to stay closed
during the lifting of the sewing foot. Then the setting of the parameter
F-196 for the function of the thread main tension and the thread
supplementary tension in relation to the sewing foot lifting is not active.
For a quick switching on and off of the reparation seam, a parameter
setting first has to be carried out.
Programming the reparation seam with key “A” of the Efka
·
operating panel V810/V820: Set the parameter F-293 to 18.
Programming the reparation seam with the key “B” of the Efka
·
operating panel V810/V820: Set the parameter F-294 to 18.
By actuating the key “A” or “B” on the Efka operating panel V810 or
V820, the reparation seam, with the thread tension being always
closed, can be switched on and off quickly.
If the reparation seam mode was switched on, at the end of the
reparation seam it has to be switched off by actuating the same key of
the Efka operating panel, in order to activate the parameter F-196
again.
26
6.2.4 Function of the thread’s supplementary tension in relation to the stroke adjustment and the
Speedomat
The thread’s supplementary tension can, at any time, be switched on
and off by actuating the key 1 (see chapter 6.16) of the machine’s
keypad. To that end, the parameter F-255 must be set to “7".

Operation mode of the quick stroke adjustment
The activation period of the maximum sewing foot stroke depends on
the set operation mode. It is possible to choose between three
operation modes.
The individual operation modes are determined by the adjustment of
the parameters F-138 and F-184 at the control panel (see enclosed
instructions of the motor manufacturer).

The maximum sewing foot stroke is engaged by
actuating the knee switch 2.
By actuating the knee switch once again the maximum
sewing foot stroke is disengaged.
The maximum sewing foot stroke remains engaged as
long as knee switch 2 is actuated.
After releasing the knee switch the machine sews with
maximum sewing foot stroke until the set minimum
speed is reached (parameter F-184).
Then the seam is continued with normal sewing foot
stroke.

6.15 Setting the stitch length
3
1
2
The special sewing machines 867 are, depending on the subclass,
equipped with two setting wheels. Thus, two different stitch lengths can
be sewn, that are activated by actuating a key (see chapter 6.16).
The two stitch lengths are set with the setting wheels 1 and 2 on the
machine arm.
–
Set the higher stitch length with the upper setting wheel 1.
Setting 1 = min. stitch length
Setting 12 = max. s titch length
–
Set the smaller stitch length with the lower setting wheel 2.
Setting 1 = min. stitch length
Setting 12 = max. s titch length
The stitch length are the same for both, forward and backward sewing .
–
For the manual sewing of tacks, push the stitch regulator lever 3
downward.
The machine sews backward stitches as long as the stitch
regulator lever 3 is being pushed.
Hint
In order to facilitate the setting of stitch lengths, the stitch length that
remains unchanged should be activated with key 2 (see chapter 6.16).
GB
CAUTION Danger of breakage!
The stitch length set with the lower setting wheel 2 must not exceed
the stitch length set with the upper setting wheel 1.
