ABSTRACT:
A web cut-off assembly for a rewinder apparatus includes a bedroll having a pair of retractable bedroll blades that move to a protracted position to engage the web material for a web cutting event. A chopper roll is disposed proximate to the bedroll and includes a first blade and a second blade extending from a circumference thereof. The first and second blades rotationally intermeshing with the bedroll blades in the web cutting event. The second blade is configured to effectively stretch and hold the web relative to the bedroll blades as the first blade severs the web in the web cutting process.
