ABSTRACT:
A manual banding tool is provided with a band tension limit, which can be adjusted while the tool is coupled to a test device, such as a strain gauge. The manual banding tool includes a shuttle mechanism for incrementally advancing the band through the tool during a forward stroke. The shuttle mechanism is mechanically coupled to a pivotally mounted handle by way of an overcenter toggle mechanism. The overcenter toggle mechanism is coupled to a spring tensioning assembly, which includes a plurality of spring members, such as Belleville washers, disposed near the rear of the tool. An adjustment screw on the rear cover portion of the tool allows the spring tension of the spring members to be adjusted. Once the band tension limit is reached, the spring members collapse, allowing the overcenter toggle mechanism to lock the handle in position thereby preventing further movement of the shuttle mechanism. The termination may then be bent by hand such that the band is at approximately a 90.degree. angle with respect to the buckle to maintain the tension in the band. A handle operated shear is then operated to allow the termination to be removed from the tool. The outwardly extending tail portion of the band is subsequently placed adjacent the rollover assembly to allow the tail portion to be fully bent over the buckle.
