20080223271 | TAPE EDGE WORK STATION - A tape edge applicator workstation including a conveyor for moving a mattress or foundation along a sewing path through a tape edge applicator. The tape edge applicator applies a tape edge material about the peripheral side edges of the mattress, with the mattress generally being rotated as the tape edge material is applied about the corners thereof. | 09-18-2008 |
20090064911 | AUTOMATIC PANEL CUTTING AND SEAMING SYSTEM - An automatic panel cutting and edge seaming system includes a series of side edge cutting and seaming assemblies that receive a fabric material and trim and sew seams along the side edges of the fabric material to form a desired width panel. Puller rolls pull the material through the side edge cutting and seaming assemblies and feed the trimmed and seamed fabric material to a cross-cut sewing assembly. After a sufficient length of fabric material has been fed to form a desired size panel, the cross-cut sewing assembly is engaged to cut and seam the end of the panel. | 03-12-2009 |
20100269743 | METHODS FOR MANUFACTURING A SELF-FORMING MATTRESS COVER - A self-forming mattress cover including a mattress gusset with a drawstring is provided. The gusset includes a sleeve attached to the gusset along a fold location. A drawstring is disposed within the sleeve. Ends of the drawstring are pulled into tension, thereby reducing the perimeter of the gusset at the fold location and drawing the gusset inward toward the center of the mattress. The gusset is formed to corner positions of the mattress by stretching and/or bunching of gusset material as tension is applied. The ends of the drawstring are secured to retain the tension state. A cushioned quilt top is attached to a free edge of the gusset. The self-forming mattress cover conforms to corner positions of a mattress without the need for mitering, ruffling, pleating, or sewing seams at the corner positions. The self-forming mattress cover also ensures proper alignment of the cushioned quilt with the mattress body. | 10-28-2010 |
20100282148 | MATTRESS EDGE SEWING MACHINE - A mattress edge tape machine is provided. More specifically, a workstation for applying a tape edge material about the peripheral side edges of bedding materials such as mattresses or foundation sets is provided. The mattress edge tape machine has a table adapted to support a work piece, at least one conveyor belt coupled to the table, a sewing head mounted directly adjacent to the table for performing a sewing operation on the work piece, and an arcuate turning arm mounted adjacent to the table to selectively turn the work piece on the table. The arcuate arm may include a clamping device for moving and securing the work piece. The machine may also include a guide assembly of actuators, instead of an arcuate turning arm. | 11-11-2010 |
20110203503 | APPARATUS FOR THE MANUFACTURE OF MATTRESS PLATES - An apparatus for the production of rectangular mattress plates from a length of material ( | 08-25-2011 |
20150020722 | FRAME FOR SEWING UPPER PILLOWS ON COVERING SHELLS FOR MATTRESSES - A frame for sewing upper pillows on covering shells for mattresses, which comprises four perimetric walls. Each wall is perpendicular to the two contiguous walls and comprises at least one laminar portion that constitutes a resting surface: at least one of the walls comprises at least one locking element for at least one component, selected from between an upper pillow and a covering shell, arranged on a respective laminar portion; at least one of the walls comprises at least two bands that are mutually aligned and can slide with respect to each other in order to vary the overall length of the wall; a linear actuator is interposed between the at least two bands of the wall, for the controlled mutual sliding of the bands; the actuator being adapted to be controlled by a respective control and management unit of a sewing machine that is functionally associatable with the frame. | 01-22-2015 |
