Abstract

1318274 Rolling plastics HERMANN BERSTORFF MASCHINENBAU GmbH 8 June 1970 [10 June 1969] 27535/70 Heading B5A A method of continuously compacting and heating, kneading and mixing plasticizable, initially particulate, plastics material to produce a sheet, comprises the steps of feeding at a controlled rate the plastics material to a nip defined by two rolls rotating at different peripheral speeds, the nip size, the rate of feed, the relative peripheral speeds of the rolls and the material itself being such that the shear stresses generated at the nip have the effect of heating the material as it is continuously compressed and kneaded to produce the required sheet, the feed rate ensuring that the material does not remain in the nip for a period to cause non- uniform heating.
