  • Paper web cutting device
    Patent number: 5582359
    Abstract: A paper web cutting device utilizes a slit shaft that is positioned adjacent pair of cooperating cylinders and which has a slit through which a paper web passes. The shaft is rotatable to transversely sever the paper web which is then rolled on the slit shaft. The shaft can be displaced away from the printing couple in a direction opposite to the direction of web travel as the paper web builds up on the shaft. The accumulation of the web on the slit shaft prevents bunching of the web or the roll-up of the web on the printing cylinders.
