Abstract
In a needle plate used in a sewing machine for forming double chain stitches, a recess is formed at a looper heel side of a needle hole behind a needle drop point. During the sewing of a fabric, the loop of the looper thread expands by tensioning of the needle thread and settles within the recess, so that balloon stitches are formed on the under side of the fabric.
