Abstract

An improved method and apparatus for the assembly of pillow-top mattress covers. In the method of this invention, the gussets for a pillow-top mattress cover are prepared in a single step in which the gusset material is folded longitudinally, and the flange material is attached thereto and the gusset material is sewn together in one stitch. Thereafter, a gusset is attached to each of the top and bottom panels of the cover along its outer edge. Each gusset is secured to the underside of its associated top or bottom panel at the folded edge using a blind stitch which is not visible externally of the panel. No gluing is required. During the step of attaching the gusset to its associated mattress cover panel, precisely positioned mitered corners are formed on the gusset where the gusset is to be attached to the corner of its associated panel. In the apparatus of this invention, a conventional blind stitch machine is modified to accept thicker work by providing a wider cam for urging work into the needle area, top and bottom feed rollers disposed even with the needle, and pneumatic control of the lower support arm.
