Setting The Looper Thread Quantity - DURKOPP ADLER 610-10 Service Instructions Manual

4.12 Setting the looper thread quantity

The released looper thread quantity is determined by the position of the
looper thread take-up. The looper thread take-up adjusts the looper thread
quantity to the relevant set stitch length so that the stitch pull is optimal for
every length and also for stitch condensing.
The looper thread take-up can be adjusted continuously on a scale from
0 to 5. The larger the value, the greater the released thread quantity and
the more elastic the seam.
Proper setting
The proper setting is dependent on the stitch length and the seam type.
You need to ensure, especially when applying extreme settings, that the
needle reliably plunges into the thread triangle:
• Elastic seam with a very short stitch length = scale 5
• Tighter seam with a significantly increased stitch length = scale 0
Disturbance due to excessively large looper thread quantity
• Missing stitches
• Looper thread jumps off the thread take-up disk

• Tilt the machine head ( p. 14)
