A sheet of fibre-reinforced resin is bent into an arcuate shape by feeding the sheet on to a suitable shaped moving surface, heating the sheet thereon until it has set hard, removing the sheet and finally cutting it into required lengths. The sheet may have longitudinal corrugations or ribs &c. which may be formed before the sheet is applied to the moving surface. A glass fibre-mat, formed at 1, is fed on to a sheet 2 of cellophane on to which a polymerizable resin 4 has been applied. A top sheet 5 of cellophane is then applied between rollers 6 and 7, the edges of the cellophane sheets being welded together. The sheet 8 then formed is then drawn over a series of corrugating rollers 9 on to the shaped rim 10 of a rotating spoked wheel 11 and passes through ovens 14, 14a-f in which the polymerizable resin is fully hardened. The hardened sheet ...

In a continuous sheet casting process, to form tufted &c. sheet material, the moulding belt is flexed during the actual casting, to facilitate complete penetration of the material into the fibre forming cavities, and is flexed again during the stripping to elongate the fibres beyond their elastic limit and to curl them (see Fig. 5, not shown). In the embodiment shown in Fig. 1, the moulding material 30 is applied to an endless flexible belt, as it is distorted over roller 16, by an ultrasonically vibrated squeegee bar 28, the material being subsequently cured or partially cured by a dielectric high frequency heater 34. Further coats 52, 54 are than applied by vibrated bars 48, 50, the coats cured by an infra red heater 60, and the finished sheet P stripped from the belt as it passes over roller 20, to cooler 64. The belt is supported over a table 38 by a second belt 40 during the baking steps and a serim or fabric may be applied. If required the belt 40 may be replaced by a sealed porous belt to which a vacuum is applied so that penetration of the material is further facilitated. In a second embodiment (see Fig. 2, not shown) both the fibre forming layer and a backing layer are applied to the belt as it is flexed over a roller, the two layers being subsequently cured in one step. In a third embodiment (see Fig. 3, not shown) a fibre forming layer is applied to the belt, a backing layer of fabric or serim then applied, the whole then being bonded and cured by a dielectric heater, cooled by passage through a water bath, and wound up on to a suitable roll. The belt is made by arranging short metal filaments 150 and magnetised chuck 152, forming a frame around the chuck, and casting a liquid rubber in the mould thus formed.

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.
