Abstract
In a method and apparatus for packaging a rolled web, a feed roller is located near each of opposed end faces of the rolled web to be packaged. The axis of rotation of a feed roller is inclined with respect to the radial direction of the roll, which radial direction intersects perpendicularly to the direction along which a wrapping material having side edge parts folded in L-shapes is fed, such that the outer periphery of the axis of rotation, which outer periphery is taken in the radial direction of the roll, is more forward with respect to the direction, along which the wrapping material is fed, than the inner periphery of the axis of rotation. A folding member is located on the side more forward than the feed roller with respect to the direction, along which the wrapping material is fed. The folding member is supported such that the space between the folding member and the opposed end faces of the roll varies periodically. The feed roller rotates to feed the side edge part of the wrapping material while the side edge part is being imparted with tension towards the center of rotation of the roll. A slack portion of the side edge part of the wrapping material, which slack portion occurs on the side forward from the feed roller with respect to the direction, along which the wrapping material is fed, is folded by the folding member at predetermined intervals onto the opposed end faces of the roll.
