ABSTRACT:
A machine for winding a body, such as a container, tubular member or the like with a tension cable which is tensioned with an adjustable force, comprises a machine carriage movable at a predetermined speed about the body to be wound. The carriage has a drive shaft, a main drive motor for driving the drive shaft, a clamping wheel mounted for rotation on the carriage for tensioning the cable, and a mechanism for maintaining substantially constant the force in the cable. This mechanism incorporates a brake which is driven by the clamping wheel and is mounted to pivot about a fixed pivot axis upon being so driven, and an auxiliary motor for auxiliary drive of the carriage. The brake transmits energy taken-up during braking to the auxiliary motor. A spring resists pivotal movement of the brake about the pivot axis, so that the brake assumes a pivotal position about the shaft dependent upon the rotational moment transmitted to the brake by the clamping wheel. The energy transmitted by the brake to the auxiliary motor is regulated as a function of the pivotal position of the brake about the pivot axis so as to change the relationship of the speed of the machine carriage to the rotational speed of the clamping wheel in such a manner that the force in the tension cable strives to approach a desired value.
