ABSTRACT:
A method and apparatus for rewinding and severing a web delivered to a winding core and then transferring the leading end of the remaining web to an empty core while the winding core is being filled. The web to be rewound and severed is passed between a vacuum transfer roll and a knife roll prior to reaching the winding core with the vacuum transfer roll being spaced from the winding core while the web is delivered thereto until such winding core is almost filled. The vacuum transfer roll is moved toward engagement with the empty core and the knife roll is moved toward the vacuum transfer roll when the winding core is almost filled. The web is severed at a location spaced forwardly of the empty core as it passes between the vacuum transfer roll and the knife roll with the vacuum transfer roll being adjacent the empty core to force the leading end of the remaining web onto the empty core.
