An apparatus for severing a web at a reversing winder comprises a cutter bar provided with a cutter blade and a roller engageable with a currently empty core tube in the winder. It is desired to provide such an apparatus which can be used in conjunction with core tubes having different diameters. This is accomplished by mounting the cutter bar carrying the cutter blade and the roller in such a manner on a traversing frame, which is movable relative to the core tubes, that the position of the cutter bar and of the roller relative to the core tubes is adjustable by a movement of the traversing frame.
