There is provided a torque device which includes a driving module, a driven module and an adjusting module. The adjusting module comprises a magnetic torque device, wherein an input end of the magnetic torque device is capable of being driven by the driving module, an output end of the magnetic torque device is capable of driving the driven module, the input end and the output end of the magnetic torque device have a variable distance therebetween, and the input end is capable of driving the output end to transfer a torque in operation.

Provided is a reel for a conductor of an electric fence. The reel includes a bobbin, a frame for supporting the bobbin, and a connector. The connector can be two jaws and can have passages to connect the reel to a support such as a conductor of an existing fence or a tube of a vehicle. One of the jaws can be wide for stability. The connector can have an electrical conductor for connecting to the support and electrifying the conductor. The connector can also be operated by a trigger and can have a locking mechanism. The frame can be a one-piece frame made of plastics material. The reel can have a spreader and a hot-up bar. The reel can have a crank that can be disengaged from the bobbin and a brake that is applied when the crank is disengaged.

The frame brake assembly includes a sleeve, a piston, a brake, and a retracting device. The piston translates within the sleeve between an upper first position and a lower second position. A brake is coupled to a lower portion of the piston beneath the sleeve. As the piston moves between positions, the brake moves in a corresponding manner. In the second position, the brake is lowered into contact with the ground. The retracting device is used to automatically return the piston and brake to the first position. When installed on the coiling machine, the frame brake assembly is coupled to the frame of the coiling machine and is in selective engagement with a pair of spool arms. Rotation of the spool arms induces translation from the first position to the second position in the frame brake assembly.

A passive tensioning system is disclosed for composite material that is dispensed by a composite placement machine. A spool is mounted on a spool shaft and material on the spool is pulled from the spool and applied to a surface. The tensioning system has a drag brake on the spool shaft and a drag brake control for the drag brake. A dancer roll is mounted on a linear slide having a spring force and a slide control is provided for the linear slide. A control system continually varies the drag brake control and the slide control to control the tension of the composite material based on the instantaneous operating characteristics of the composite placement machine.
