METHOD AND APPARATUS FOR ASSEMBLY OF PILLOW-TOP MATTRESS COVERS

摘要

In a method for the assembly of pillow top mattress covers (11), the gussets (20, 22) for a pillow-top mattress cover (11) are prepared in a single step in which the gusset material is folded longitudinally, and the flange material (34) is attached thereto and the gusset material is sewn together in one stitch. Thereafter, a gusset is attached to each of the top (14) and bottom (16) panels of the cover (11) 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. In the apparatus of the invention, a conventional blind stitch machine is modified to accept thicker work by providing a wider cam (186) for urging work into the needle (152) and pneumatic control of the lower support arm (124).
