ABSTRACT:
A clamping device or anchor, at least two of which are used to clamp onto separated sections of a conveyor belt, which sections lie to each side of a repair site in the belt, whereby the belt sections can be pulled together by a power mechanism affixed between the clamping devices, whereby belt tension is relieved at the repair site to allow a repair to be made more easily, wherein each clamping device is provided with a stop shoulder which is adapted to engage an outer edge of the belt as the belt is positioned edgewise between a pair of upper and lower jaws of the device, and wherein the belt contacting portions or surfaces of the jaws are spaced inboard of the stop shoulder from about ¼ inch to about 1.0 inch such that the belt outer edges are not clamped and are not subject to tearing forces.
