Needle plate for a twin- or triple-needle interlock sewing machine has a tongue between the needle holes on the line of fabric travel, to hold the thread loops on an angled sliding path with a buffer zone to retain thread loops

摘要

The needle plate (1) for a twin- or triple-needle interlock sewing machine, to sew a chain stitch seam with two or three threads, has two or three needle holes (2) with a forwards stitching tongue (3) between each pair of holes in the direction (V) of fabric travel. The tongue leaves free a thread guide gap (4). The needle plate, for a twin- or triple-needle interlock sewing machine, has a sliding path (8) at an upwards angle at the under side (6) towards the tip of the tongue for the thread loops (F). The angled sliding path has a flat buffer stretch (9) to prevent the thread loops moving immediately from the holding tongue and, at the same time, hold at least two thread loops.
