Abstract

A drum opener for severing a metal clamping band on a drum to enable the cover to be removed from the drum. The drum includes a cylindrical metal wall having a plastic liner and the upper edge of the wall and liner are rolled outwardly along with the peripheral edge of the cover to form a chime. A metal clamping band is secured around the chime to seal the cover to the drum. The drum opener includes a base which supports a power source such as an electric gear motor and a drive wheel is journaled on the base and is disposed to engage the upper portion of the clamping band. A rotatable cutter is disposed in engagement with the lower portion of the band and is out of direct alignment with the drive wheel. The cutter can be manually adjusted to bring the cutter into engagement with the clamping band. To prevent twisting of the opener during operation, a pair of arms or outriggers extend outwardly in opposite directions from the base and guide members are positioned on the ends of the arms and are disposed to ride on the clamping band as the opener is moved in its path around the drum by operation of the drive wheel.
