Abstract
A method for winding sheet material from a assisting roller onto a roll includes the step of exerting a compensating force in a compensating force direction on a shaft of the roll. The compensating force at least partially counteracts a bending stress in the shaft due to a gravitational force from the roll and/or a contact force from the source roll. The shaft includes two ends that are disposed to rotate on bearings. The bearings are spaced apart and disposed near the two ends. The space between the bearings defines a winding space of the roll. An apparatus for practicing the method is also disclosed.
