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.

A method for packaging a rolled web, wherein a leading edge part of a wrapping material having side edge parts, each of which has been bent into an L-shape from the middle part of the wrapping material, is brought onto part of the outer circumferential portion of a rolled web, which is to be package
A method for packaging a rolled web, wherein a leading edge part of a wrapping material having side edge parts, each of which has been bent into an L-shape from the middle part of the wrapping material, is brought onto part of the outer circumferential portion of a rolled web, which is to be packaged, such that the bent corners of the wrapping material are located at side edges of the outer circumferential portion of the roll to be packaged, and thereafter the roll to be packaged is rotated such that the wrapping material may be fed forwardly, whereby the wrapping material is wound around the outer circumferential portion of the roll to be packaged, wherein the improvement comprises the steps of: i) locating a feed roller in the vicinity of each of opposed end faces of said roll, which is to be packaged, the axis of rotation of said feed roller being inclined with respect to the radial direction of said roll to be packaged, which radial direction intersects perpendicularly to the direction along which said wrapping material is fed, such that the outer periphery of said axis of rotation, which outer periphery is taken in said radial direction of said roll to be packaged, is more forward with respect to the direction, along which said wrapping material is fed, than the inner periphery of said axis of rotation, which inner periphery is taken in said radial direction of said roll to be packaged, ii) locating a folding member on the side more forward than said feed roller with respect to the direction, along which said wrapping material is fed, said folding member being supported such that the space between said folding member and the opposed end faces of said roll to be packaged varies periodically, iii) rotating said feed roller while it is being in contact with the side edge part of said wrapping material, said side edge part wrapping material being thereby fed while said side edge part is being imparted with tension towards the center of rotation of said roll to be packaged, and iv) folding a slack portion of said side edge part of said wrapping material, which slack portion occurs on the side forward from said feed roller with respect to the direction, along which said wrapping material is fed, by said folding member at predetermined intervals onto said opposed end faces of said roll to be packaged.
