Abstract
A dry end tail cutter for a papermaking machine comprises a slotted housing for accommodating the traverse of a cutter in a cross machine direction relative to the machine. A drive motor mounted on the housing drives a slot closing band around a pair of opposed pulley wheels. The slot closing bank is entrained around the pulley wheels and has its opposite free ends interengaged with a motor mount disposed within and slidable relative to the housing. A knife motor is carried by the motor mount and moves therewith. A rotary knife is driven by the knife motor. The band functions to close the slot forwardly and rearwardly of the knife as the motor mount and knife are traversed in the cross machine direction relative to the papermaking machine.
