ABSTRACT:
A system for sensing a web break using web break detection instruments. Upon sensing a break a strategically located, full web width deflection cam bears against the machine web upstream of the detected break. Under the bias of the deflector, the web running route is pushed into a saw-toothed cutter blade. Saw-tooth points simultaneously penetrate the web along a line traversing the full web width. Such line of web penetration becomes an immediate line of full width web breakage but at a location along the machine length designed to accommodate the waste production (broke) until web continuity along the remainder of the machine length is restored.
