Abstract

Multi-part mould for the mfe. of a power transmission belt i.e. V-belt, by injection moulding, is formed as an annular space and has an annular groove running at a radial spacing from the annular space and connected to this by a slit shaped passage for the simultaneous feed of elastomeric material to all zones of the annular space.
