ABSTRACT: An apparatus for the repair of rubber or plastics conveyor belts, usually having reinforcement inserts, and for making them endless. The basic components of the apparatus are press plates which can be heated, upper girders, lower gliders and hydraulic pressure-producing equipment. The girders are connected together in pairs by tensioning bolts with mechanical tightening facilities. The girders undergo bending deformation under a specified pressure, with a defined deflection curve or bending line. The pressure-producing equipment acts between one of the press plates and the associated girders, and consists of hydraulic tubes which are of constant perimeter but the cross-section of which can be deformed. The tubes are supported one one side by the associated girder, and on the other side on a pressure plate constructed with a U-profile. The distance of the pressure plate from the associated girder is adjustable and is so adjusted that in the operating condition the hydrau- lic tubes posses an oval cross-section. Conse- quently they can act as pressure-producing equipment, although constructed as hydraulic tubes of constant perimeter. The deflection of the girders can be compensated by a deflection curve compensator.
