Container cutting assembly

摘要

A container cutting assembly includes first and second parallel counter-rotatable shafts defining first and second axes. A first and second plurality of cutting wheels are positioned on the first and second shafts, respectively, interleaved with cutting wheels on the other shaft. Each cutting wheel has several cutting teeth, each tooth having a leading surface and two trailing surfaces. The second trailing surface has a preselected length. The leading surface and first trailing surface define a cutting edge, which is skewed with respect to the respective axis, defining a cutting point. Each cutting wheel is positioned on the shaft such that each cutting point of each tooth passes between two second trailing surfaces of cutting teeth disposed on either side approximately midway along the preselected lengths thereof. The cutting points of corresponding teeth in each plurality of cutting wheels align in lines which are parallel and coplanar to the respective axes. A driver drives the shafts, and a suspension system is provided between the driver and the shafts to absorb and release excess energy applied to the assembly.
