An apparatus for measuring and correcting uniformity of tyres

摘要

The invention provides an apparatus for measuring and correcting the uniformity of tyres. The apparatus includes two transfer conveyors for transferring tyres which are arranged substantially parallel to one another. Each conveyor has support means for supporting and rotating a tyre conveyed to the support means by the respective transfer conveyor. In addition, the apparatus has a rotary drum for measuring the uniformity of a tyre supported by the support means of one of the transfer conveyors. The rotary drum is movable between the support means of the respective conveyors so as to measure the uniformity of tyres supported by the respective support means. Grinder mechanisms are provided with each transfer conveyor for grinding a tyre to correct the uniformity of the tyre. The apparatus is controlled such that as the uniformity correction of a tyre supported by the support means of one of transport conveyors is carried out, the uniformity measurement of a tyre supported by the support means of the other of the transport conveyors is carried out. This enables a more efficient operation. <IMAGE>
