Abstract
A method and apparatus for winding an elongate web into a convolutely wound roll either on a core ensleeved on a mandrel or on the mandrel itself and which include providing a center wind rewinder defining an upstream to downstream path having in sequence a web direction changer and a turret indexably rotatable about a first axis and equipped with a plurality of orbiting circumferentially spaced rotatable mandrels. The rewinder has an articulatable arm member indexably rotatable about a second axis outside the orbit of the mandrels. The method includes advancing a web at a predetermined speed in the path from the changer onto a first mandrel and winding the web thereon, moving a second mandrel into confronting relation with the web upstream of the first mandrel while continuing to wind the web on the first mandrel, moving an articulatable part of the arm member into contact with the web to press the web toward the second mandrel, and rotating both the arm member and articulable part to achieve a resultant speed at least as great as the web predetermined speed to sever the web and start winding the web about the second mandrel.
