Abstract

975,615. Moulding elastomeric sheet material; laminates and laminating. AMERICAN BILTRITE RUBBER CO. Inc. May 2, 1963, No. 17322/63. Headings B5A and B5N. A sheet material having a hirsute or suedelike finish is formed by sheet casting a layer of an elastomeric resinous material, hardenable by polymerization, fusion or vulcanization, upon an endless flexible moulding belt 20 having a multiplicity of passages 15 upon its moulding surface. As shown in Fig. 6, a decorative film or layer of ink, for retention upon the finished article, is applied to the moulding surface of the belt 20 by a printer 23, after which a layer of a polyvinyl plastisol 24 is applied by a spreader 25. The belt then passes through a semi-evacuated chamber 26, to completely fill the passages 15 with plastisol and then through a heating chamber 30 to solidify the thus formed layer after which the layer is stripped from the belt. If required, a second layer of material 27 may be applied by a spreader 28. A backing layer, e.g. a textile ply, or a layer of foamed or unfoamed elastomeric material, which is coated with a heat-actuated adhesive and may be embossed or printed, may be applied from a roll 31 by a roll 34 after passing under an infrared, steam, or electric heater 32. The laminate thus formed is passed through a cooler and then stripped from the belt over rolls 35 and stored on roll 36. The moulding belt is formed by pressing a board carrying needles or the like (see Fig. 1, not shown) into a soft substance which may be hardenable to form a primary negative mould from which is produced a series of positive moulds which are conjoined either by cement or a backing layer 10 from a large positive mould. A large negative mould 20<SP>1</SP> of e.g. rubber is then cast from the large positive mould, several such negative moulds being joined to form the moulding belt 20. The passages in the belt may be of different depths in different areas to produce a variegated surface pattern. Specification 929,442 is referred to.
