PCT No. PCT/NO95/00119 Sec. 371 Date Feb. 13, 1997 Sec. 102(e) Date Feb. 13, 1997 PCT Filed Jul. 3, 1995 PCT Pub. No. WO96/01181 PCT Pub. Date Jan. 18, 1996The pressure compression mould for the production and/or revulcanisation of tires forms a hollow space where the pressure and the temperature can be regulated. Each sidewall of the compression mould is designed with an elastic and flexible annular disc membrane which the sidewalls of a tire placed in the mould is made to thrust against in order to control the outwardly directed tensile forces in the tire. The membrane sides facing towards the mould hollow space is equipped with an annular disc-shaped membrane-protective plate in order to prevent direct contact between side faces of the tire and the respective membranes during the production/vulcanisation. The plate is split up, both in the radial and circular plane, into a series of smaller plates the free ends of which mutually overlap each other. When a tire is placed in the mould and the mould hollow space is pressure set, the sides of the tire are pressed outwards towards the plates which flex afterwards and furthermore the membrane is flexed outwards and is stretched. Direct contact between the membrane and sides of the tire is avoided so that the sides of the tire are not vulcanised fast in the membrane.
