Abstract: Carrier roll winder for winding a material web divided by longitudinal cuts, e.g., a paper or board web, which has two carrier rolls arranged to form a roll bed on which the wound rolls rest with axes aligned as they are wound up. A pressure roll system is included, which has a crossmember running horizontally and displaceable vertically, to which a pressure roll having an axis parallel to the crossmember is fixed. The crossmember, including the pressure roll carried by it and other units carried by it, has a mass M of 9.25·I2.5, where M is the mass in kilograms and I is the length in meters. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: Rewinder and Method for threading a material web into a rewinder, in which the start of the material web is drawn off a supply roll at full width by an auxiliary device in order to improve automation possibilities. Further, provision is made for the material web to be fed to a winding position at full width and for the auxiliary device to be released from the material web in the region of the winding position.
