Abstract
1,243,317. Extruder worms. HERMANN BERSTORFF MASCHINENBAU G.m.b.H. 20 March, 1970 [19 April, 1969], No. 13567/70. Heading F2U. [Also in Division B1] An extruder worm consists of a number of coaxial hollow sections 1, 2, 3 mounted on a splined hollow spindle 4 and held together by an axial tie rod 8, the inner end of which has a flange 8a bearing against a bayonet abutment 1a on section 1, while the other end carries an adjustable nut 9 for varying the compression of axial loading springs 5.
