Abstract

The mould consists of upper and lower tools, circumferential segments between, and a ring to form each bead. At least the lower ring is fixed to an axially moving tube which withdraws to release its bead after moulding. To prevent the ring from cooling when opening the mould, a U-ring heating channel is welded on to the tube immediately below the ring.
