An appliance for the repair of rubber or plastics conveyor belts 1, usually having reinforcement inserts 2, and for making them endless, comprises heatable press plates 3, 4, upper girders 5, lower girders 6 and hydraulic pressure-producing equipment 7. The girders 5, 6 are connected together in pairs by tensioning bolts 8 with mechanical tightening facilities 9 and undergo bending deformation under a specified pressure, with a defined deflection curve or bending line. The pressure- producing equipment 7 acts between one of the press plates 3 and the associated girders 5, and consists of hydraulic tubes which are of constant perimeter but the cross-section of which can be deformed and which are supported on one side by the girder 5, and on the other side on a U-profile pressure plate 12. The distance of the pressure plate 12 from the girder 5 is adjustable and is so adjusted that in the operating condition the tubes 7 possess an oval cross-section. The deflection of the girders can be compensated by a deflection curve compensator 11. The tubes 7 may be arranged either parallel to or transversely of the girders and may either be connected to a common source of pressure medium or be tightly sealed but contain an incompressible liquid. <IMAGE> |
