Abstract
A cutting apparatus, suitable for cutting or shearing a moving web, comprises first and second wire segments that contact each other at substantially a single point and includes means for causing the point of contact to travel along the length of the wire segments to accomplish the cutting of a web positioned between the wire segments.
Claims12
Cutting apparatus comprising first and second wire segments that contact each other at substantially a single point and that are segments of a single continuous loop of wire, means for maintaining each wire segment taut comprising first and second spaced apart beams, each supported for limited rotational motion about a pivot point and each including spaced apart bearing members about which said single wire is trained, and means for moving at least one of said segments relative to the other to cause the point of contact to move along each of the segments.
