Abstract

1,236,624. Moulding plastic substances. BURROUGHS CORP. 25 Oct., 1968 [15 Nov., 1967], No. 50858/68. Heading B5A. [Also in Divisions B3 and B6] In a method of making a printing drum comprising circumferentially spaced rim segments 103, Fig. 12, each having a web 102 and a flange 104 with type characters 106, the segments are held by their webs between spacers 115, 119, Figs. 2 and 3, located on the inner faces of endplates 107, 109 of an annular centrifugal mould 105 to which a predetermined quantity of moulding material is fed. The latter may comprise a low melting point alloy or an epoxy resin, plaster or rubber. The material is fed to the mould cavity via an inlet 121 and apertures 111, and as the mould rotates about its axis the material encapsulates the flanges 104 and when hardened the segments are held together to provide an assembly 100, Fig. 4, not shown, which is placed within a second mould, Fig. 5. The latter comprises end caps 135, 133 with coaxial apertures to receive a shaft 131; moulding material, e.g. a synthetic resin, is fed through openings 141 in the cap 133 to fill the inner cavity of the assembly and secure the shaft thereto. The initial encapsulating material is then removed, e.g. by immersing the assembly in a hot water bath.
