Members DanishMan Posted June 22, 2024 Members Report Posted June 22, 2024 Dear Friends I am working on a PFAFF 331 9B. I am puzzled about the maximum stitch length. It is sewing with about 3 mm stiches. I was expecting 4 mm stitches. Anyone here with knowledge of the PFAFF 331 9B? Kind regards Danishman Quote

Kind regards Danishman Expand The 331 is similar to a 335 in the fact the feed dog doesn't lift the material off of the needle plate when it goes back.This creates alot of drag esp in sticky materials like vinyl & leather & will cause the length to shorten.You could have some worn feed parts,lift the foot up & push the needlebar front to back & try the feed dog too to see if there's any play.
