Abstract

697,466. Seaming non-metallic sheets. OPPENHEIMER CASING CO. (U.K.), Ltd. Feb. 6, 1951.. [Oct. 11, 1950] No. 24871/50. Class 42 (i). Apparatus for sealing together the edges of thermoplastic sheets comprises a base member with a resilient support member secured thereto, and a plurality of movable frame members, of which one is adapted to co-operate with the support member to position between them the sheets to be sealed, a second is provided with means for applying heat to the edges of the sheet to seal the same, and a third is provided with a cover strip of heat resistant material and is adapted to position the same between the heat applying means and the said edges. The support member may be of polyvinyl chloride, and the cover-strip of tracing cloth, fibre glass cloth, or the like. As shown three frame members a, c, and e are pivoted at g on a base k, on a resilient support j on which rest the sheets f, undergoing sealing. The frame a carries an electricallyheated copper bar b and the frame c a strip d of tracing cloth or the like. All three frames are adapted to be brought downwards into operative position by a handle h.
