Abstract: A temperature-controllable roller 1 is used as the sealing tool, on whose circumferential surface a plurality of plastic film webs are sealed together under the action of heat and pressure. The plastic film webs, which are conveyed about compression rolls, run at equal or different mutual distances onto the circumferential surface of the temperature-controllable roller. These compression rolls rest against the circumferential surface of the temperature-controllable roller and exert pressure onto the latter. The webs of plastic film run through the contact nips between the compression rolls and the temperature-controllable roller. The plastic film webs are provided on one or both sides with sealing layers, which are incipiently melted by the action of heat, so that a sealing of the plastic film webs in layers one on top of the other occurs on the circumferential surface of the temperature-controllable roller.

Abstract: A method of preparing an in-mold label is described in which a resin film is embossed to form a gravure pattern having from 60 to 200 roll-formed lines per inch. The embossed film is stretched and then coated on its embossed pattern side with a heat-sensitive liquid resinous adhesive in an amount of from 1 to 10 g/m.sup.2 on a dry resin basis.

Abstract: A thermoformable mat, e.g., a mat of resinated fiberglass, is compressed and shaped into a contoured object, e.g., a shell for an automobile headliner, by this process. The mat is compressed between two dies that have been preheated. At least one of the dies is perforated. Superheated steam (e.g., at 80 psig and 600.degree. F.) is ejected from the perforations into the mat, thereby quickly raising the mat temperature to its thermoforming point. After the mat is set into the contoured shape, the dies are reopened and the formed mat is removed. If the mat that is used contains a thermoplastic adhesive, the mat is cooled to below the adhesive's melt print before the dies are opened. This can be done by applying a vacuum to the perforated die and pulling ambient air through the mat.

Abstract: A process for creating decorative laminates comprising a resin based substrate layer, a barrier layer impermeable to the reaction products produced during the curing of the substrate resin and subsequent heating of the resultant laminate, and a decorative layer formed by a decorative ink pattern is disclosed. The barrier layer, which is located between the substrate layer and the decorative layer, prevents the reaction products from reaching the decorative ink pattern when the substrate resins are cured during laminate processing, and, during subsequent heating of the final product, acts as a sink for heat stress and prevents combustible toxic gases from passing through the laminate into the surrounding environment. Thus, destructive of the decorative ink pattern during laminating processing is prevented. Further, the resulting decorative laminates have high heat release thresholds and reduce the risk of flashover in enclosed areas.

Abstract: The invention provides an efficient method for the preparation of a plastic-made computer-operating card having an emboss-worked relief pattern on the surface by adhesively bonding an emboss-worked plastic-made covering sheet to a body of the card. In the inventive method, a sheet for covering is lined with a second sheet on the back surface and the laminate is emboss-worked so that the debris of the second sheet fills up the cavity formed behind the relief pattern in the first sheet followed by peeling off the undeformed portion of the second sheet leaving the debris filling the cavity. Since the cavity behind the emboss-worked relief pattern is filled up with the debris of the second sheet, the emboss-worked covering sheet is safe from the troubles of collapsing or flattening in the subsequent step of adhesive bonding thereof to the body of the card.

In this case the portion of backing material pressed into contact with the cover is partially melted to bond the backing material to the cover.

Abstract: Non-woven fabrics produced from spunbonded web of the thermally bonded type suitable for use in folding window blinds are disclosed. To provide an opaque fabric with a weave-like finish a metalized blackout film and the spunbonded web substrate are laminated together while simultaneously embossing the substrate. Non-opaque fabrics may be made by using a film without metalization. Binder material is added to provide corrosion protection for the metalized film and additional bonding to the substrate. Difficulties in embossing this type of web are overcome by using steel embossing rollers and narrow widths of web. Using this basic process opaque fabrics may be made without embossing by creating a temporary bond between the layers with the surface tension of water, or non-opaque fabric made by not adding any film in the embossing step.

Abstract: An improved means is disclosed for continuously forming tiles that are embossed in register with a printed design. A printed design is first applied to a base coat and a wear coat is laminated over the design. Advantageously, the wear coat is applied to the printed web before it is heated for lamination. Before embossing occurs, the laminated product is cooled until partial setting occurs, and the embossing roll is sprayed with water in order to minimize the likelihood that the laminated product will adhere to the embossing roll. To avoid distorting the web during lamination and embossing, proper web tension is maintained by controlling the rotational speeds of the laminating drum and the embossing roll so that a desired ratio is preserved. The web is then cut into oversized tiles that shrink to size during annealing.

During fabrication of the laminated product, a thermoplastic low-viscosity wax-like substance, such as melted wax or paraffin, hot melt plastic or the like, is applied in minute amounts onto juncture lines of pressure bonded spots formed in the pads. The thermoplastic material penetrates the layers of the laminated product so that, on cooling, it forms a "wax rivet" at each bonded spot, thus providing added strength for the juncture lines and rendering the layers impervious to absorbed liquid at the points of application.
