Abstract

1,098,946. Making sheet material. DUNLOP SEMTEX Ltd. May 6, 1965 [May 30, 1964], No. 22487/64. Heading B5A. A sheet 15 is formed by preheating thermoplastic particulate material 2 between heated steel belts 3 and 4 and passing the self-supporting sheet 7 thus formed between an endless tensioned heated steel belt 8 and a steamheated roller 9 in order to compress it to its final thickness. The belts 3 and 4 may converge (as shown) and are heated by platens 5 themselves heated by, e.g. electricity, gas burners or steam. If a terrazo effect is required upon one surface of the sheet, the belt which contacts that surface is maintained at a lower temperature than the other belt. Alternative pressing and heating means may act intermittently and may comprise press platens.
