A track and flap assembly employs an elongate compressible foam member completely covering an elongate channel that carries a paper cutting tape. Between the bottom of the foam member and the top of the channel are one or two pivotally mounted resilient flap members that cooperate with the foam member to provide a desired frictional drag and exiting resistance to control the cutting tape movement during turn up. A compressed air passage is provided to allow for forced air removal of debris and other contaminants from the tape channel. The assembly is constructed in two configurations to accommodate different papermaking apparatus.
