Material feed problems
(stitch length different from settings)
Possible reasons:
-
feed dog setting is not correct, material cannot be caught sufficiently.
-
unsuitable feed dog toothing
-
different pressures on the left and right hand feed plates
-
feed plates lift is blocked
-
material accumulation in the needle plate, mainly over cross seams
-
seam or loop are caught by the feed dog
-
unintended stitch length modification
-
spring-loaded plunger blocks in the cross seam area
Solutions:
-
check feed dog setting and stitch length, replace feed dog, if
necessary
-
set material support pressure correctly
-
check if lower side of needle plate, feed or sewing parts are
damaged and replace or repolish them, if necessary
-
choose correct needle plate for thicker materials (see “7 Variable
sewing tools” and “8 Optional extras”)
-
only for machines with spring-loaded plunger:
check the functions of plunger and limit stop, re-adjust settings, if
necessary
