12.4 Adjusting the guide plates with additional spring loaded downholder at the folder
Caution: Danger of injury !
Switch off the main switch.
Check and adjust the guide plates only with the main switch
switched off.
Standard checking
According to the material thickness and considering whether the flap is
to be positioned on the right or on the left the height of the guide plates
has to be adjusted in such a way that they can easily be lifted by the
workpiece. The guide plates have to be close beside the needles, but
must not touch the needles or the needle block.
The guide plates and the spring loaded downholder should press the
fabric in a controlled way during the sewing process.
The independent setting of the guide plates and the spring loaded
downholder (position and pressure) allows a better processing of
various materials.
–
Check the position of the guide plates.
–
Check the spring pressure (important with regard to the folding and
seam quality).
–
Check the free movement of the needles 2 and needle block 3 with
regard to the guide plates.
