Patent number: 5059270Abstract: In a process for the welding of plastic films lying flat, one on top of the other, the plastic films are brought into contact with a heated cutting edge and hot-tool welded. Two-layered or multilayered composite films of different chemical composition are used for the welding; for example, one composite film can be an opaque, colored or uncolored layer, on which there is arranged a transparent sealing layer comprised of a propylene-ethylene copolymer or a propylene-ethylene blend. The sealing layer of the opaque composite film is welded directly to a sealing layer of a second, transparent composite film.Type: GrantFiled: March 16, 1989Date of Patent: October 22, 1991Assignee: Alkor GmbH KunststoffeInventors: Edgar Fleischmann, Maximillian Mayr, Heinrich Heitz

Patent number: 4478660Abstract: A method for forming a laminate which is composed of a decorative layer and a carrier panel comprising applying a crosslinking plastic foam onto a decorative carrier web, subjecting the thus coated web to heat treatment to dry and partially crosslink the foam and then marrying the unfoamed side of the web to a carrier panel with the application of heat and pressure so as to further crosslink the foam. Laminates in accordance with the invention are described. Such laminates possess stability against delamination as well as relative freedom from gaseous inclusions.Type: GrantFiled: February 27, 1980Date of Patent: October 23, 1984Assignee: Alkor GmbH KunststoffverkaufInventors: Josef Landler, Max Mayr

Patent number: 4418106Abstract: A method for producing a flocked web by applying a layer of a thermosetting plastic foam onto a carrier sheet which foam penetrates into the surface of the carrier, flocking the uncrosslinked layer and then thermally hardening the layer and wherein prior to complete crosslinking of the flocked layer, the partially crosslinked flocked layer is submitted to heat pressing. In a preferred embodiment, the heat pressing can include an embossing step. The process of the present invention is not only easy to carry out, it avoids the presence of air bubbles as well as other inconsistancies in the product. The product obtained with the present invention is also disclosed.Type: GrantFiled: April 12, 1983Date of Patent: November 29, 1983Assignee: Alkor GmbH KunstoffverkaufInventors: Josef Landler, Max Mayr
