POWER-OPERATED BANDING TOOL Abstract of the Disclosure A power driven banding tool utilizes, for example, a pneumatic motor, electric motor or other means of motive power for progressively driving the band through the tool. The tool is provided with a rotary drive mechanism which includes a knurled wheel and a plurality of spring loaded pinch rollers for gripping the band. The driving torque for the knurled wheel is provided by a worm gear assembly by way of an adjustable clutch. The worm gear assembly is opera- tively connected to a pneumatic or electric motor. The adjustable clutch allows the pull pressure to be calibrated to the desired limits. An Oldham type coupling is provided between the motor output shaft and the worm gear input shaft to overcome any axial misalignment. The tool also includes a handle operated rollover assembly for bending the band around the buckle to maintain the tension in the band so it can be cut off. A cut off assembly is operatively coupled to the pivotally mounted handle for actuating a cut off blade in the front of the tool to cut the band. A final trim assembly is further provided in the chin of the tool to trim the excess band flush with the top of the buckle.
