Publication number: 20090004939Abstract: An insect screen comprised of knitted synthetic yarns and having a knitted pattern incorporated therein. First and second groups of yarns, such as polypropylene, are knitted with the first group of yarns forming a grid or mesh while the second group of yarns form a pattern. Once the insect screen is knitted, the insect screen is subjected to a finishing operation. In finishing the insect screen is stretched and placed in tension using selvages formed of a third group of yarns. The tensioned insect screen is heated causing the yarns to at least slightly plasticize and causing heat fusion of at least some stitches. Thereafter the insect screen and yarns are cooled, resulting in the insect screen becoming more rigid and generally assuming the stretched configuration in the absence of stretching.Type: ApplicationFiled: June 27, 2007Publication date: January 1, 2009Inventor: Claus Graichen

Patent number: 7371699Abstract: A net-reinforced film structure includes a film layer and a netting attached to the film layer having a pattern of netting strands. The netting strands are sealed to an opposing film structure, which may be either a similar net-reinforced film or a standard sheet of film, along a linear seal area. The netting strands in the non-sealed areas of the net-reinforced film structure are free from attachment to the opposing film structure. The netting strands along the linear seal area have a wider cross-section than the netting strands at the non-sealed areas, and this wider cross-section facilitates the sealing process.Type: GrantFiled: July 19, 2004Date of Patent: May 13, 2008Assignee: Pactiv CorporationInventor: David A. Bryniarski
