Abstract

1510005 Die lip adjustment in extrusion calendering HERMANN BERSTORFF MASCHINENBAU GmbH 22 Oct 1975 [23 Oct 1974] 43393/75 Heading B5A Plastic material, e.g. rubber, is delivered into the nip 4 of contra-rotating calender rolls 5, 6, Fig. 2, from the transversely elongate passage 14 of an extruder die head whose outlet 18 is defined between lips 23, 24, which are replaceably mounted, so that when the roller nip is reduced in thickness, the material accumulating in the nip is also reduced, Fig. 1, by extending the passage 14 further into the nip and reducing the thickness of its outlet 27, by means of another pair of replaceably mounted die lips 25, 26, Fig. 1.
