Abstract
Abstract The specification describes a vulcanising mould for vehicle tires, comprising a first side wall mould part with radially outwardly extended support arms, a second side wall mould part and a tread mould ring subdivided into radially movable profile segments. The profile segments have conical sliding shoes on their outer surface. These shoes are provided with a surrounding part whose internal surface is conical. The surrounding part serves to produce radial movement of the profile segments when relative axial movement takes place between the surrounding part and the tread mould ring. The axial guide means of the first side wall mould part in the surrounding part comprises recesses in the surrounding part in which the extended carrying arms of the first side wall mould part can be displaced axially. The radial guidance of the sliding shoes of the profile segments is ensured by support screws which can be displaced radially in slots in the support arms.

Total Claims: 12
Claim 1
Independent Claim
210 words
A vulcanising mould for vehicle tires comprising a first side wall mould part with radially outwardly extended carrying arms, a second side wall mould part and a tread mould ring, which is subdivided into radially movable, guided profile segments, having their outer surfaces provided with conical shaped sliding shoes, said shoes being further provided with an axially movable surrounding part having an inner side of conical shape, the surrounding part serving to drive radially the profile segments upon relative axial movement between the surrounding part and the segments of the tread mould ring, and the first side wall mould part in the surrounding part is guided in an axially movable manner in relation to the surrounding part, the surrounding part having guide means comprised of recesses provided along the interrior of the surrounding part for receiving and guiding the first sidewall mould part, whereby the extended carrying arms of the first side wall mould part can be displaced axially within the recesses, said carrying arms having radial guide means comprising slots for radially guiding the sliding shoes of the profile segments, support screws being movable in the radial guide means slots and secured to the shoes for supporting the said shoes and to provide for radial movement of the segments.
