Abstract

1311885 Drawing billets through dies IMPERIAL CHEMICAL INDUSTRIES Ltd 23 June 1970 [1 July 1969] 33230/69 Heading B5A Oriented elongated polymeric articles are made by drawing a thermaplastic billet having an oriented leading end or "nose" through a die, the billet being gripped by the "nose". Drawing may be assisted by extrusion, for example by hydrostatic extrusion using a fluid such as a silicone, mineral or vegetable oil to lubricate the die. The "nose" may be formed upon the billet by extrusion. Tubes, rods, T or I bars or the like may be drawn.
