Abstract: A method of applying a heat activated ornamental transfer to a foraminous substrate such as a mesh shirt employs an absorbent layer to absorb portions of the transfer which cover holes in the foraminous surface. The heat activated transfer is positioned on the substrate with an absorbent material underneath the substrate. Heat and pressure is applied to the heat activated transfer causing it to bond to the foraminous substrate. This same heat and pressure also causes that portion of the transfer covering holes to bond to the absorbent material beneath the substrate. While still warm, the absorbent material is separated from the material pulling with it the portions of the transfer which cover holes. This leaves the holes clear providing an extremely pleasant aesthetic appearance.

Abstract: Sheet material for use in vehicle safety air bags comprises a multiplicity of perforated films of polymeric material having holes, the perforated films being superposed on each other such that the holes in adjacent films do not overlap to any great extent, and adhesive filling the holes of all of the perforated films other than the outermost ones and uniting them into a laminate.

Abstract: The present invention relates to an apparatus and method and uses a thin, yet strong plastic film as the intermediate layer for the waterproofing material and the film has a plurality of perforations therein. The film is highly resistant to crack propagation, and acts as a barrier to crack propagation between adjacent asphalt layers, thus providing superior protection from the elements. The asphalt layers are interconnected with each other through the perforations in the polyester support layer. Because of the strength of the polyester film, only a very thin layer of polyester is necessary and this results in a substantial cost savings. As an alternative to coating, it is possible to extrude or laminate the asphalt onto the PET film. Also a layer of asphalt may be applied only to one side of said film and extruded through the perforations with heads on the columns so formed to attach the asphalt to the film.
