Abstract

A centrifugal machine 10 comprises a rotating hollow cylinder 11 for the production, under the action of centrifugal force, from a hardening liquid material poured into the cylinder, of an article in the form of a sheet 19 of plastic material from which discs may be cut for buttons. The cylinder 10 comprises a first annular wall 11 and a second annular wall 13 superimposed internally over the first so that it is removable and with its surface turned towards the inside of the cylinder and shaped to form die surfaces for the liquid material poured into the cylinder. The advantage is that the second annular wall 13 that shapes the sheet-like part 19 is flattened by contact with a die with a shaped surface and is made from a relatively resilient material to permit it to be inserted into the hollow cylinder 11. <IMAGE>
