    摘要: 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.

    摘要: A method for forming a partial mattress sack which prevents radial bunching includes feeding first and second panels having different edge lengths at different rates through a sewing machine to form the partial mattress sack. An apparatus for sewing the partial mattress sack includes a mechanism for driving upper and lower walking feet at varying rates and a mechanism for driving the upper walking foot at the same speed as a second lower walking foot.

    摘要: An improved method and apparatus is provided for use in a sewing machine. The improvements include preloading two pieces of material which are to be sewn together. The preloading is accomplished by positioning pieces of material to be sewn under a gripper spaced from the sewing head on a table while prior pieces of material are being sewn. The gripper engages the material and, when the prior sewing operation is completed, the gripper is moved across the table toward the sewing head to load the preloaded pieces of material. When the two pieces of material are preloaded, most of the material hangs over an edge of the table and the lengths of the pieces of material are determined by movable detectors.
