ABSTRACT:
A coiling apparatus, wherein a band tension regulator is operatively coupled with a hydraulic cylinder for controlling a friction drive of a coiling drum whose rotation speed is governed in a control circuit. The control circuit couples a device for maintaining a constant slip in the friction drive of a coiling drum and a hydraulic drive of a coiler mounted for a reciprocating movement along the axis of the coiling drum, whereby a constant coiling pitch is maintained regardless of variations in the rotation speed of the coiling drum shaft.
