  • Patent number: 5857391
    Abstract: Device for cutting a protective layer away from a material roll of web-formed material, comprising a rotation device which rotates the roll. The rotation device includes at least two rotatable carrier rollers, on which the material roll is supported and is rotated. In this way the protective layer on the material roll is cut away from the roll during a cutting operation by a cutting tool device. This contacts the roll during its rotation. The rotatable carrier rollers form lifting and carrying devices on a mobile load carrier in order to support the material roll whilst rotating it during the cutting operation and in order to transport the material roll to and, respectively, from a chosen place for the cutting operation.
