LAMINATED FABRIC AND ITS MANUFACTORING PROCESS

A laminate or a laminated article with integrated raised zones having the appearance of buttons, borders, surrounds, folds or the like is specified. A process for producing such a laminated article is also specified. The laminated article consists of a textile or vinyl synthetic resin cover layer, a foam intermediate layer and a layer of substrate material, for example a polyamide. A shaped article having the desired shape for the raised zone is inserted between the foam layer and the cover material layer. Anhydric polyurethane foam-forming materials are applied in liquid form onto the foam layer, the contact surface of the cover material and the contact surface of the substrate material. Before the lamination, the layers are placed on a mould, the shaped articles being arranged directly above those mould projections which follow the contours of the mould projections. Moisture is introduced into the foamable material and a heated press is caused to act on the substrate material, the layers lying one above the other being pressed downwards against the mould. The press force with simultaneous heat supply causes a foaming reaction of the foamable material, leading to a foam adhesive layer which substantially adhesively bonds the cover material to the substrate material in the zone surrounding the shaped articles. The binder layer also bonds the cover material and the substrate material to the other surfaces of the foam layer.

Improvements relating to the manufacture of upholstered panels using dielectric heating

841,996. Bonding by dielectric heating. RADIO HEATERS Ltd. Jan. 25, 1957 [Nov. 7, 1955], No. 31791/55. Class 39(3). [Also in Group VIII] In the formation of an upholstered panel using radio frequency dielectric heating to bond two sheets of material forming the sides of the panel, pressure is applied to selected portions of the panel to compress them in sequence progressively over the area of the panels, the portions then being bonded while they are under pressure. Undue strain in the material forming the sides of the panel is thus avoided. As shown in Fig. 3, electrodes 14a-14e are lowered in sequence to compress portions of material 8 and 12, the cover material 8 moving from right to left over wadding 10 without undue stretching. Welding power is then applied between the electrodes 14 and the common electrode 18 and bonding takes place. The backing material 12 of the panel so formed remains approximately flat and a pronounced quilting effect is produced on the upper surface of the panel. Unnecessary compression of the wadding layer may be reduced by loading bars 36, Fig. 6, which consist of a series of rods or strips, and are inserted under the cover material before the bonding operation. Withdrawal of the bars after the fluting welds have been completed results in a maximum formed shape of the cover 8 and a deep upholstered appearance of the panel. The cover material and backing material may be thermoplastic sheeting, e.g. P.V.C., which may be either unsupported or supported on an open-weave backing cloth. The wadding may consist of felt, cellulose, paper, sponge rubber, foamed vinyl, polyurethane foam, or synthetic fibre ; coatings or sheets of glues or resins may be used to promote the bond between the cover and backing. Pneumatic rams or a series of cams may operate the movable electrodes which may be given a shape corresponding to the form of the indentations required.

Trim panel manufacturing apparatus and method of fixing trim panel to support

A trim panel, having a finish material cover layer (40b) bonded to a heat responsive backing material (40), for example, for covering the interior surface of a car door, is made in a molding apparatus in such a way that the contoured edges (42) of the molding tool form a finished panel rim around the trim panel simultaneously with the molding of the trim panel. The backing material (40) is, for example, a thermoplastic foam and/or a thermoplastic fleece material which is heated for the molding. The cover material (40b) for the finish cover layer is, for example, cloth that is cooled during the pressing, to avoid damage to the cover material. The finished rim is formed by shaping the surface layer material (40b) and simultaneously densifying the material of the backing material (40) at least along the edge of the panel without any need for folding the cover layer (40b) around the panel edges. The rim is then secured in a groove of a substrate, e.g. by an adhesive, by heat welding, or mechanically, e.g. by a location fit that is possible due to the rigidity of the rim. <IMAGE>
