ABSTRACT:
Device and method for packaging a material web roll, having a longitudinal axis, with a packaging sheet. The device may include a carrier positioned to carry the material web roll, a packaging sheet dispenser positioned to be movable parallel to the longitudinal axis and to dispense the packaging sheet onto at least a portion of a longitudinal extend of the material web roll to form an acute angle between a dispensing direction of the packaging sheet and the longitudinal axis, and a positioning sensor positionable to determine an axial position of the material web roll on the carrier. The method may include substantially continuously determining an axial position of the material web roll during the helical wrapping and controlling an axial advance of a packaging sheet dispenser in accordance with a momentary determined axial position of the material web roll.
