Abstract
The present invention concerns a mould for the forming of soles made of expanded polyurethane, having a premoulded rubber tread, which is embedded at the centre of the bearing plan of the sole. The mould in question has an annular ribbing at the bottom of the die cavity, inside which is made an impression able to exactly accommodate the premoulded rubber tread, having a small perimeter lip which finds exact support and mating above said annular ribbing, while the cover has an annular series of vertical tips arranged so that they come to press down in proximity to said lip, flattening it on the support and abutment ribbing underneath. <IMAGE>
