Claim Text:
1. An apparatus for making a conveyor belt having a cable core, having at least a cable unwinder having a plurality of cable spools from which the cables, to be embedded in the conveyor belt are unwound, a combining device in which the cables, which are under tension and extend longitudinally of the belt parallel to one another in a plane, are combined with one or more raw rubber webs to form a raw belt, a vulcanizing press in which the raw belt is vulcanized by pressure and/or heat to form the conveyor belt, the cable unwinder having a cable unwinder and tensioner in which each cable is individually tensioned to the required production tension, the individual cable spools each being with or connected to at least one tension actuator or tensioning drive that set a tensioning torque necessary for producing the required production tension of the cable, and at least one cable-tension sensor in the cable unwinder and tensioner for measuring tensions of the individual cables at one respective measuring point on each cable.
