ABSTRACT:
A fencing wire unwinder and tensioner, and method, for constructing wire fences, the apparatus comprising a carrying platform for spools and rolls of fencing wire, whereby the wire is unwound and tensioned in a single operation for attachment to the preset posts of the fence. According to one embodiment, the device is adapted for barbed wire only; to another embodiment, woven wire only; and a third embodiment both barbed and woven wire. Spools of barbed wire strand and/or rolls of woven wire are carried rotatably on a platform, the wire being fastened to the fence to be unwound therealong as the platform is carried along the fence line by the vehicle. As the wire is unwound from the roll it is tensioned before leaving the platform by a braking disc (barbed wire) or an elongate braking drum (woven wire). A braking band is provided for each of the drum and the discs so that the wire is adjustably tensioned as it is drawn from the apparatus. Helpers follow the platform and attach the fencing in tensioned condition to the preset line of posts. According to one aspect of the invention, a hydraulically operated locking device holds the woven wire in tensioned condition while a fresh roll thereof is attached for subsequent unwinding and tensioning.
