US 2002/0117575 A1 · Apparatus and method for severing or separating a web

Abstract

An apparatus, system and method are disclosed for separating and/or winding a web. A web is adhered by vacuum force to a rotating transfer roll. A turret is provided that is capable of indexing about a longitudinal axis, the turret having a plurality of mandrels rotatably affixed to the turret. A web passes to the transfer roll and to winding position of the turret. A severing means, such as an air knife, water knife, interference device, or severing roll is configured to separate the web. The web may be synthetic, textile, or paper. The web may be perforated at periodic intervals so that the web sections may be separated at pre-existing perforations and then wound upon mandrels of the turret in a continuous operation.
