Abstract: A novel method and apparatus are provided for making an improved welded joint between overlapping lengths of thermoplastic strap. The welded joint includes a central region and an adjacent peripheral region. The pressure on the strap joint during formation is released first in the peripheral region and subsequently in the central region. An embodiment of the apparatus for making such a joint includes an anvil, a central strap-engaging member, a peripheral strap engaging member, and a mechanism for moving the anvil sequentially to three positions. At a first position the overlapping strap lengths are pressed between the anvil and both the central and peripheral strap-engaging members. In the second position of the anvil the peripheral strap-engaging member does not press against the strap lengths while the central strap-engaging member continues to press the strap lengths against the anvil.

Abstract: The present invention provides a new and improved method for manufacturing vehicle interior trim panels such as door panels and instrument panels in which different regions of the trim panel have different colors or other aesthetic characteristics. Two pieces of sheet vinyl having the desired color or other aesthetic characteristic desired in the manufactured trim panel are cut to shape and then bonded together edge-to-edge to form a composite two-tone vinyl sheet. This composite vinyl sheet is draped over a mold having a blade projecting from the mold surface. A retainer is installed onto the backside of the composite vinyl sheet to attach the composite vinyl sheet to the blade and thereby hold the vinyl in place with the bond between the two sheets located at the apex of the blade. The mold is closed and urethane is poured against the backside of the composite vinyl sheet to encapsulate the retainer.

Abstract: A process for producing a liquid-container material that includes a thermoadhesive resin film, a substrate sheet having a thin-film layer of an inorganic compound, such as a silicon oxide, and a paper substrate. The thermoadhesive resin film is formed by melt-extruding a thermoadhesive resin from an extruder die, and then cooled to a temperature at which the thermoadhesive properties inherent in the thermoadhesive resin film can be retained and at which no crack is produced in the thinfilm layer of an inorganic compound when the thermoadhesive resin film is laminated to the substrate sheet. The cooled thermoadhesive resin film is laminated to the substrate sheet to form a laminate, which is then laminated to the paper substrate. The thermoadhesive resin film may preferably include a non-adsorptive resin layer and a thermoadhesive resin layer. In this instance, the non-adsorptive resin layer is so provided as to be on the outside of the liquid-container material.

Abstract: Disclosed are a process for producing a tubular nonwoven fabric and tubular nonwoven fabrics produced by the same.

Abstract: A method and apparatus for making a drip irrigation device by continuously extruding a tube and simultaneously feeding a plurality of dripper units in succession within the tube as it is extruded. Each dripper unit is arrested as it arrives at a first location which is a short distance downstream of the extrusion head where the extruded tube is still tacky, and is then moved transversely to bring it into light contact with the tacky surface of the extruded tube to cause the dripper unit to lightly adhere to the tube and to begin to move axially with it. A short distance downstream of the first location where the dripper unit has attained the same axial velocity as the extruded tube, the dripper unit is pressed into firm bonding contact with the tacky inner surface of the extruded tube.

Abstract: Disclosed is an insulated metal door edge guard having a stainless steel body, a PVC cover, and a sheet of colored PVF. The PVC cover is coextruded completely around the metal body in strip form. Then, before the heat of the coextrusion step is lost, the PVF sheet is laminated onto one surface of the PVC cover. The combination is then roll formed into a door edge guard having a base and two legs. The ends of the legs are folded inward to form two beads. The PVC cover has two regions of decreased thickness on the interior of the beads to facilitate the roll forming of the beads.
