Abstract

1479159 Calendering sheeting HOECHST AG 19 Dec 1974 [19 Dec 1973] 54898/74 Heading B5B Thermoplastic material is extruded in the form of tubular sheeting 4 from an extruder 1 fitted with a blow head 2, inflated, flattened by guide rollers 5 and squeeze rollers 6 and 7, passed through calender rolls 10 with gap 10a where a bank of kneading mass 9 is formed, and then withdrawn and trimmed by knife 12. The original width b of the sheet before calendering is the same as the finished width after cutting off the edges 14.
