Abstract: An apparatus and method for coating a substrate with plastisol and depositing pebbles into the ungelled coated plastisol is presented. A powder containing fusible particles compatible with the coated substrate and the pebbles is then deposited by at least one rotary silk-screen printing frame and thereafter a heat treatment is carried out in an oven or with infrared lamps at a temperature below the distortion temperature of the substrate in order to set the deposited materials.

Abstract: A process for the manufacturing of plastisol based synthetic coverings (e.g. floor or wall coverings) having improved resistance to soiling; and the product produced from the process is presented. The synthetic covering utilizes a wear layer formed from a mixture comprising at least one silicone polymer and a cross-linking agent. Preferably, this mixture also includes a catalyst. The mixture is deposited onto a conventional support as a wear layer. The silicone polymer is then cross-linked and the wear layer undergoes pre-gelling and gelling.

Abstract: A process and product is presented for obtaining selective areas of distinctive appearance, i.e., matting on synthetic coverings. The process includes, depositing a polymeric coating which contains at least one radiation initiator for polymerization onto at least a first selected area or zone on an expandable or non-expandable support substrate. Next, at least one second coating comprised of a crosslinkable monomer is deposited onto a second selected area on the substrate. This second area or zone may encompass at least a portion of the first area. Thereafter, pre-gelling is performed on the deposited material followed by a graining operation which is carried out over at least a portion of the substrate surface. The synthetic covering in the first zone or area is then polymerized by radiation initiation wherein the particular appearance thereof is fixed to the substrate. Thereafter, gelling is carried out wherein the polymer which has not been fixed by radiation initiation will flow, i.e.

This second area or zone may encompass at least a portion of the first area. The first and second initiators should be triggered by distinct "spectral zones", i.e., a range of temperature conditions, frequency conditions, etc. capable of decomposing the initiator to form free radicals or ions needed for chain propagation in a polymerization reaction.

Abstract: A composite floor covering product comprising a layer of low-porosity support material, such as asbestos, is produced by a process comprising the steps of(a) perforating a low-porosity support material,(b) coating a compact PVC plastisol precoat onto at least one face of the perforated low-porosity support, and(c) finishing the product with various coatings and decorations, comprising at least one fusing or gelling stage.

Abstract: Textured sheet material is produced by a process which includes two printing steps and two separate applications of plastisol in the form of discontinuous layers. The plastisol layers are applied over respective of the printed patterns and the first layer of plastisol is gelled, but not fused, prior to the second printing step which provides an image thereon. The process enables production of a relief pattern having "valleys" of two different depths.

Abstract: A technique for the manufacture of synthetic sheet material having a textured surface and suited for use as floor or wall covering. The technique in accordance with the invention includes the printing of a decoration on a support member and the applying of a transparent plastisol in the form of a discontinuous layer over and in accordance with the decoration. The invention also contemplates the application of a continuous wear layer which, in the final product, will either be disposed between the discontinuous transparent plastisol and the decoration or will cover the discontinuously applied plastisol which provides the textured effect.
