Abstract: A method and apparatus for laminating a decorative lamination film to an extruded substrate is disclosed. The decorative lamination film may be clear, translucent, pearlescent, or opaque and it is compressed against the extruded substrate between a pair of rollers. In the context of vertical blind louvers, the rollers and the decorative lamination film are wider than the extruded substrate, the side edges of the extruded substrate being temporarily pressed upward in contact with the lamination film. The roller in contact with the lamination film is heated to a temperature sufficient to melt a central length of the lamination film that is contact with the extruded substrate, and thereby under increased pressure, but not so hot as to melt the unused side lengths of the lamination film. The unused side lengths, therefore, do not melt and naturally separate from the central length.

Abstract: A method of manufacturing a multi-layered web uses contoured honeycomb drums for the manufacture of non-woven webs used to make the multi-layered web. The method can use spunbonded, melt blown, or electro-static spun techniques for depositing solidifying filaments on outer collection surfaces of a multi-drum system. The multi-drum system may be employed to improve multi-layered web uniformity and the overall quality of the multi-layered web by presenting a single optimal collection surface for each independent web layer being produced.

Abstract: This invention relates to a cushioned dust control mat article wherein the mat comprises at least two distinct layers of rubber, one comprising foam rubber, the other comprising solid rubber. The solid rubber layer is present over the foam rubber layer on the side of the mat in which at least one integrated rubber protrusion is present to provide cushioning characteristics. The solid rubber layer acts as a cap or barrier for the foam rubber layer, particularly over the integrated protrusion or protrusions, in order to provide a mat which is resilient, will not easily degrade in its modulus strength after appreciable use and/or washing within industrial cleaning processes, and will not exhibit appreciable cracking or breaking, particularly within the integrated protrusion(s), after standard use for pedestrian traffic. A method of producing such an inventive cushioned floor mat article is also provided.

Abstract: A spunbond web formation apparatus includes a spinneret (1) of a spin pack (2) that extrudes an array of fibers (5) that are drawn into an aspirator (6). The attenuated fibers (8) discharged from aspirator (6) are deflected sideways by a Coanda device (7) that entrains the exiting air stream along with the fibers. The fibers are deposited on a vertically moving belt (9) and subsequently bonded by calender rolls (20, 21) to form a non-woven spunbond web. The spinning distance L is adjusted by vertically moving the aspirator (6), while the laydown distance M is adjusted by horizontally moving the belt (9) or aspirator (6) or by adjusting the size of the Coanda device (7). Deflection of the fibers exiting the aspirator permits the spinning distance L to be adjusted independently of the laydown distance M, without having to move the spin beam or adjust the height of the web-forming belt.

Abstract: A process for making a protective and decorative surfacing film comprises extrusion coating a solid polymeric material from an extruder die to form an optically clear first layer of uniform film thickness on a smooth surface of a carrier sheet traveling continuously past the extruder die opening. The extrusion coated first layer is immediately cooled on the carrier sheet to harden it, followed by applying a pigmented second layer in thin film form to the first layer to form a composite paint coat in which the first and second layers are bonded to each other. The composite paint coat is then transferred to a supportive backing sheet or substrate panel, after which the carrier sheet is separated from the paint coat, to expose the outer surface of the first layer as a high gloss surface with a high distinctness-of-image, providing a transparent protective outer coat for the underlying pigmented second layer.

Abstract: A method produces a decorative sheet with the use of an apparatus having a metallic endless belt that is wound on a first roller and a second roller, and an emboss roller that is placed to abut through the metallic endless belt onto the first roller. The method includes the steps of: adhering a first resin sheet having a pictured layer onto the metallic endless belt abutting the first roller; running the first resin sheet, adhered onto the metallic endless belt, along the outer circumferential face of the emboss roller; guiding a second resin sheet, moltenly extruded from a molten-resin extrusion means, between the emboss roller and the metallic endless belt abutted to the first roller; laminating and joining the second resin sheet to the first resin sheet; and embossing patterns onto the second resin sheet with the emboss roller during the laminating and joining step for the first and second resin sheets.

Abstract: The method consists of introducing the dripper units (1) one after the other inside a conduit (2) while the latter is being formed in an extruder (10), then calibrated in a calibrator (13), heat welding the dripper units (1) to the inner wall (3) of the conduit (2) gradually as it progresses downstream of the extruder (10), then cooling the conduit (2) and perforating it opposite each dripper unit (1) to make it communicate with the exterior. According to the invention, the heat welding operation is executed downstream of the calibrator (13) by pinching the dripper unit and the wall of said conduit between first and second opposing surfaces (20, 22b) one of which is driven at the speed of progression of the conduit (2) and the other is arranged on a fixed support member (16) forming a feed guide for the dripper units (1). The dripper units are presented for the pinching operation one after the other contiguously by their ends.
