iMPERIAL BATISTE AND BROADCLOTH - HAVE POLYSTER BLEND AND COTTON. You could try running a long sheet of waxed paper through your needles and see if that helps - I don't know how often you have to change the needles on a pleater - my husband bought me one as a gift quite a few years ago - the woman who served him sold him a thread box and a smocking board but not a single extra needle.... SAJ pleater... I could not believe no extra needles....
So maybe someone can junp in and say if 8 dresses the needles need changing especially where they were jamming... but I would try the waxed paper first....
When I learned to help my granny thread her knee press singer sewing machine I don't think that they changed the needles unless they broke... Since the needles on the pleaters are so expensive to replace I would try the waxed paper then pleat something like 100% cotton batiste or even a man's 16x16 hanky to see if it improves.
