5.3 Inserting and removing the material
ATTENTION!
The operating personnel should observe the sewing range
carefully during the sewing.
Otherwise: DANGER of finger bruises and needle through
stitches/punctures.
When the machine is in standstill position and the needle is placed approx.
7 mm within the feed cup, by opening the front cup up to approx. 14 mm by
either actuating the treadle or the pneumatic cup opening the sewing material
can be inserted or removed easily.
Put the sewing material edge to edge and then place it up to the height limit
stop of the material guide, close the front cup and start sewing.
When using a stop motor the needle is positioned automatically after the
sewing process when heeling the treadle.
Not till then the thread can be torn over the edge of the feed cup and the
material can be removed, or the material is removed and the thread is cut using
scissors.
5.3.1 Sewing
Class VTD410EV is used for attaching the insole to the upper. A pneumatically
controlled gathering device in combination with a differential feed adjustable
during sewing (see point “5.2.4 Setting the differential feed (Fig. 15)”) facilitates
gathering of extra fullness at the toe part of Volcano and leather shoes of a
medium thickness. The result is a neat seam which is completely covered
during the subsequent vulcanizing process.
