The present invention relates to a yarn tensioning system for keeping at least one yarn, which is taken from a yarn storage system to a yarn take-off system of a weaving machine, under tension. The system includes a brake roller around which the yarn is at least partially wound, and a motor for supplying a torque to the brake roller, the motor being actuable in generator operation to keep the yarn under tension between the brake roller and the yarn take-off system. In addition, the present invention relates to a weaving machine comprising such a yarn tensioning system, as well as a method for keeping at least one yarn under tension, the at least one yarn being taken from a yarn storage system to a yarn take-off system.

Technologies are described for restraining systems. The systems may comprise a base, a stationary arm, a swing arm, a rod, first straps, and second straps. A bottom end of the stationary arm may be attached to a first end of the base. A bottom end of the swing arm may be attached at a second end of the base. The rod may be attached to top ends of the stationary arm and the swing arm. First straps may be attached to the stationary arm and configured to loop around and support an object. Second straps may be attached to the swing arm and configured to loop around and support the object. The rod may move and push the top of the swing arm away from the top of the stationary arm. A friction force between the first and second straps and the object may be effective to restrain the object.

Method and apparatus for an assembly which is attachable to a skid-steer or similar front end loader or tractor which is used to install fence wire, including woven wire. The assembly contains a plurality of spindles upon which rolls of wire can be placed, which wire passes through a threader which organizes and separates the wire, then through a clamping device operated hydraulically using electric and hydraulic controllers, then over a roller and around an upright wire guide whereupon the wire is attached to a fence post in a conventional manner. The wire is clamped using a clamping member operated by a hydraulic cylinder to clamp and lock the wire so that the wire can be stretched by the engine powered skid-steer, front end loader or the like so that the wire can be tightly attached to each fence post in a series operation. The plurality of spindles is disposed on an upright central stanchion attached to a platform so that the wire can be easily placed on and removed from the spindle. An alternative embodiment is shown for use with woven wire.
