I’m having trouble
with my serger. It seems to pull on the
seam as it sews, so that the seam
ends up sort of “gathered” very slightly.
If I pull on the back end of the material
to keep it going then I can get a nice result,
or I can try afterward to work from the middle
towards the ends to pull out the gatheredness,
but I think it ought to work better than that!
I figure it must be that one of the threads
is not feeding fast enough, but I’ve adjusted the
tension so that the stitch looks pretty much
like it’s supposed too; just the lower loops
come a little bit too far around the edge toward
the top. But the machine is pretty new, and I’m
wary of adjusting the threads too far away from
the middle point, because I think the machine is
probably made so that the middle point gives an
estimated even tension for the machine to work right.
It’s a Pfaff. Can anybody tell me how to get rid
of this problem or which thread might be the culprit?
