Patent number: 8458837Abstract: 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.Type: GrantFiled: February 11, 2011Date of Patent: June 11, 2013Assignee: L & P Property Management CompanyInventors: Steven Marcangelo, Steve Wall, Justin R.

Patent number: 7617787Abstract: A tucking attachment for a sewing machine having a tucking blade with one end positioned adjacent material and a tucking blade drive with an output shaft mechanically coupled to the tucking blade. A control, connected to the tucking blade drive, is operable to command displacement to form a tuck in the material adjacent a presser foot of the sewing machine. Thereafter, the sewing machine is operated to sew a number of stitches in the tuck, and the tucking blade is then retracted. Repeating the above cycle of operation permits successive tucks of different lengths to be formed in the material.Type: GrantFiled: April 3, 2006Date of Patent: November 17, 2009Assignee: L&P Property Management CompanyInventor: Steven Marcangelo

Patent number: 6983706Abstract: A bedding foundation is manufactured with a cover having a welt cord extending upwardly to create a seal when a mattress is placed on the foundation. The cover is made using a two stage process. During the first stage a sewing machine is used to join a welt cord to a web of border material. In the second stage a second sewing machine sews a piece of non-skid decking to the border assembly. Fullness may be incorporated into the border material to enable the cover to fit around the corners of the bedding foundation with the welt cord being spaced inwardly from the perimeter of the foundation.Type: GrantFiled: December 6, 2004Date of Patent: January 10, 2006Assignee: L&P Property Management CompanyInventor: Steven Marcangelo
