Abstract

Arrangement for producing piped openings in cut blanks of garments, comprising a displaceable supporting plate and a folding device including a folding slide for piping strips defined by movable folding tools and a working blank clamp displaceable relative to the needles of a double needle sewing machine having a separating cutter working centrally between the needles and adapted to be lowered upon the cut blank, two folding and clamping rails defining a folding shaft between them supported for vertical movement and pivotally supported at their upper ends for rocking movement toward and away from one another and relative to said folding slide, means for raising and lowering said folding and clamping rails together by an adjustable distance relative to a cut blank in said folding shaft.
