ABSTRACT:
The housing of web sectioning apparatus having a rotary knife assembly and a rotary cutting drum is provided with a pair of bearing surfaces. A frame is pivotally mounted on these bearing surfaces, and the rotary knife assembly is rotatably mounted to the frame eccentrically of the pivot axis between the frame and the housing. Thus, by pivoting the frame relative to the housing, the axis of rotation of the rotary knife assembly can be moved towards or away from the cutting drum to adjust the degree of engagement between the edges of the knife assembly and the cutting drum. Clamps are provided to force the frame against the bearing surfaces of the apparatus to prevent movement at the pivot axis between the frame and housing during operation. These clamps are released to allow adjustment. The frame can be pivoted in small increments to finely adjust the position of the knife assembly rotation axis relative to the cutting drum.
