Abstract

828,482. Rollers. HARDIE & CO. PTY Ltd., J. July 10, 1957 [July 20, 1956], No. 21871/57. Class 42 (2). [Also in Group XXVIII] A pressure roller for a machine for making asbestos cement pipes comprises a resilient work surface composed of the outer faces of a multiplicity of separate pressure elements. The roller 15 has a layer of resilient material 16 such as rubber, which is divided by a number of circumferential and longitudinal grooves 19 into a series of pressure elements 17 having faces 18 the total area of which lies between 18 and 60% of the original total cylindrical surface.
