Method and apparatus for shirring a fabric

摘要

A shirring attachment for a sewing machine that includes a programmable control operable to independently control the operation of individual shirring tools that are located at different points across the width of the material to be shirred. The shirring control stores a plurality of different shirring pattern programs some of which represent shirring patterns that vary across the width of the shirring material. Consequently, a number of shirring patterns can be produced that were not previously possible. Further, the shirring attachment is designed for a high production environment in which sewing machines operate at up to 1,000 stitches per minute.
