Abstract

1422814 Rollers HERMANN BERSTORFF MASCHINENBAU GmbH 5 Oct 1973 [21 Oct 1972] 46543/73 Heading F2U A roll (for rolling out plastics to form a sheet) comprises a shell 1 encircling a core 2 from which it is spaced and supported by resilient elements 3, 3a, 3b, of stiffnesses increasing from the ends towards the centre of the roll. The elements 3, 3a, 3b may be metal tubes with different bores, and may be welded together with rods 4 and end caps 5a to form channels in a circuit 9 ... 15 for a heating medium. The elements 3, 3a, 3b, and rods 4 may be located in shallow grooves (3c) Fig. 3 (not shown) in the core.
