ABSTRACT:
In apparatus having an endless pressing band, formed of a layer of rubber with a steel-wire fabric connected thereto, passing around a heating drum, two associated guide rollers and a hitch roller, the relative positions of advancement of the opposite ends of a transverse weft wire of the steel-wire fabric are sensed by photoelectric cell arrangements and, upon sensing of a lagging of one end behind the other, control means are activated to move the bearing at one end of the hitch roller towards or away from the heating drum while retaining the axes of the hitch roller and the heating drum in a common plane.
