Abstract

1293618 Moulding tyres CONTINENTAL GUMMI-WERKE AG 20 May 1970 [6 June 1969] 24387/70 Heading B5A The plates 1, 2 of a press are associated with mould halves 3, 4 between which tread producing segments 5 are radially guided inwardly by an annular holder 6 with a guide surface 7 when the press is finally closed and the plate 1 is lowered relative the mould half 3. The parts 1 and 3 are urged apart by pins 12 spaced around the periphery of the plate, each connected to a hollow piston 10 acted upon by a compression spring 15 which is compressed within a cylindrical housing 9 when the plate 1 is lowered relative the adjacent mould half. The mould parts 3-6 may be replaced by a two-part mould, each part supported flush with the surfaces 1<SP>1</SP>, 2<SP>1</SP>, in which case the pins are compressed to lie with their ends flush with the surface 1<SP>1</SP>.
