Apparatus and method for edge stitching/binding workpieces
US 3712254 A
Abstract
An apparatus and method for the edge stitching/binding of fabric workpieces in which the workpieces are introduced into a sewing machine at a speed synchronous with that of the sewing machine and in a precise orientation relative to the needle thereof. The workpieces optionally have a tape folded about the edge thereof and are automatically fully stitched at a substantially uniform distance from the edge thereof, whereafter the workpieces are severed into separate entities. During the stitching operation each workpiece is caused to traverse a stitch pattern which consists of a random sequence of straight lines, concave and convex curved portions, by control means which constantly engage the workpiece and which work in conjunction with holding means selectively movable into engagement with the workpiece. The fully stitched workpieces may then be automatically discharged from the apparatus.
