Abstract
781,446. Laminated materials. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 29, 1953 [Oct. 14, 1952], No. 1863/56. Divided out of 781,443. Class 140. A flexible strip material, e.g. belting, is formed by superimposing three or more layers of textile 1 impregnated with a thermoplastic material, e.g. polyvinyl chloride, and enclosing said layers in a binding layer 2 of the same thermoplastic material having edges overlapping along the centre of the strip and securing together the overlapping edges 5 of the binding layer by highfrequency dielectric heating applied under mechanical pressure exerted by electrodes 3 and 4 so as to hold the layers together in a composite assembly which may then be passed between heaters and rollers to form a homogeneous strip. Pressure is exerted on the overlapping edges to minimize or avoid sparking across air gaps in the surfaces of the layers prior to heating by using the apparatus of Specification 781,445, [Group XI], or that of Specification 781,444, [Group XI].
