Multi-needle sewing machine and method for producing a stitching pattern in a sewn workpiece

摘要

The invention relates to a chain stitch multi-needle guilting machine with stitch-forming quilting elements and a method for creating a pattern in a guilting material. The elements of the quilting machine are comprised of at least one needle bar with attached needles and at least one looper shaft with attached loopers. Each of the needles and the loopers have a corresponding needle thread and looper thread associated therewith, form quilting element pairs, and are driven to build chain stitches in a quilting material. At least one of the needles is adjustable between two positions and participates in the quilting procedure in a first position and does not prick into the quilting material in the second position during the quilting procedure. The quilting machine can be made to have a device to knot the needle thread with the looper thread, or a device to cut the looper thread, or both.
