The Feed Dog - Necchi Supernova Instructions Manual

THE FEED DOG

The purpose of this part is to feed the fabric regularly for a certain
distance at every stitch so that the space between one
perforation of the fabric by the needle, and the next one, equals
the desired length of stitch.
A perfect feeding operation is of great importance for the final
result of sewing. An incorrectly operating feed dog will cause
irregular feeding of the fabric, unequal length of the stitches, and
a seam which is not straight. There are many circumstances
which may cause the defects just mentioned.
Before further investigating the causes of incorrect feeding, it is
necessary to make certain that the various parts of the feeding
mechanism are properly assembled (see instruction for "Timing of
Feed Dog and Needle Bar "). Here are some adjustments of
other parts of the feeding mechanism:
Adjustment of any looseness in this mechanism.
Adjusting the height of the teeth above the needle plate.
Alignment of the feed dog in relation to the feed dog slots and the
needle plate.
Alignment of the underside of the presser foot in relation to the
teeth of the feed dog (this adjustment is very important for the
straight feeding of the fabric).
