  • Patent number: 6073824
    Abstract: An apparatus and method for cleanly breaking a continuously advancing cellulose web includes a transfer fabric which supports and advances the cellulose web to a wind up zone. The transfer fabric forms a closed loop and is driven at a desired speed by a drive roll. At least two spray nozzles are arranged transversely across the advancing cellulose web as it is carried on the transfer fabric. The spray nozzles are capable of emitting a liquid under high pressure against the advancing cellulose web to form perforations across the width thereof. A plurality of hollow cores are independently and sequentially moved into position at the wind up zone to receive the advancing cellulose web. The hollow cores are located downstream of the spray nozzles and each hollow core is capable of accumulating a predetermined amount of the cellulose web.
