Abstract
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.
Claims21
A track assembly for guiding a cutting tape transversely across a moving web of paper being wound on a roll and transferring the cut web to an empty roll, said assembly including a track and a track support, said track being an elongated member having an upper portion and a lower portion and a first mounting means for supporting said track on said track support and a longitudinal channel formed in said upper portion for containing a length of a cutting tape therein, said channel being covered by a compressible means along said channel adapted to be compressed to uncover said channel when a cutting tape is exiting said channel, second mounting means for securing said compressible means to said track, said compressible means providing a controlled resistance against a cutting tape exiting said channel to assist in control of a tape spooling on an empty roll.
A track assembly for guiding a cutting tape transversely across a moving web of paper being wound on a roll and transferring the cut web to an empty roll, said assembly including a track and a track support, said track being an elongated member having an upper portion and a lower portion and a first longitudinal channel formed in said lower portion for supporting said track on said track support and a second longitudinal channel formed in said upper portion for containing a length of a cutting tape therein, said second channel being covered by an elongated compressible means adapted to be compressed to uncover said second channel when a cutting tape is exiting said second channel, mounting means for securing said compressible means to said track, said compressible means providing a controlled resistance against a cutting tape exiting to assist in control of a tape spooling on an empty roll.
