Abstract

Split mould for casting or moulding a belt pulley with a bearing shell consisting of a different material than the remainder of the pulley, employs a core round which the bearing is placed. The core is one half of the mould fits together with a coaxial auxiliary core in the other. The cores contain crossed channels, which are blocked when the bearing has been inserted, but are entered by the melt when not. The method is used in the prodn. of plastic pulleys.
