7. SPREADING OF A MATERIAL
Loose fabric, especially thin, can cause missing stitches unless it is spread. The machine is equipped
by a mechanism to control the extent of fabric spreading. It is possible to adjust the mechanism after
removing the table covers. Size of the spreading is possible to adjust with covered table.
7.1. After loosening the screws Ì is possible to change the spreading size of the every foot clamp
separately by the screws Í. By turning the screws Í clockwise, decreases spreading ,
counterclockwise increases, maximum is 2,5 mm on one clamp plate.
Check it with stepping (section D2) to the place, where is the stitching plate between the clamp
plates. The edge of the plats Ò has to be 1mm from the stitching plate.
7.2. Home position of the levers in spread state is set by the screw Ê under the table covers Ë. The
screw is locked by the yellow colour from the manufacturer, that is why it is not possible to
adjust it during the guarantee period. It is adjusted to the measure approximately 9.5 mm
(71.5 mm when the plate is inserted and spread).
7.3. Basic measure for a control yoke Ð adjustment is 27 mm from base for the cylinder holder Ñ
by maximum spreading (loosing the screws Ì Í).
7.4. The manufacturer recommends to adjust approximately. 0,6 mm. It is difference between the
lever stud Ï distances before and after spreading.
