ABSTRACT:
A method and apparatus for removing a section of a sheet of material being wound on a roll. The apparatus removes the section and then positions the lengths preceding and following the removed section in overlapping relationship with one another so that the overlapped lengths can be wound onto the roll. In the preferred embodiment, the preceding length of the sheet is temporarily displaced from the travel path by a vacuum plate and, during the temporary displacement, the section to be removed is moved downstream to a discharge position and the following length is moved into overlapping relationship with the displaced preceding length. Additional winding assemblies for winding the sheet onto other rolls can be used to provide a substantially continuous winding operation.
