| 20100320307 | Enveloper Assembly for Winding Webs - In a winding assembly for winding web rolls, an enveloper assembly is used to initiate winding of a web stream onto a pre-formed core or to initiate winding of a core-forming substrate into an in-line core. The enveloper assembly comprises a first support arm operatively coupled to a second support arm; a third support arm operatively coupled to the second support arm; and an enveloper roller operatively coupled to the third support arm. The enveloper roller is movable along a cylindrical surface from a first position to a second position. The enveloper assembly accommodates a wide range of core diameters. For winding non-adhesive web streams, a tail tucker can be used in conjunction with the enveloper assembly to initiate winding. In conjunction with apparatus for inserting core-forming substrates or adhesive tabs onto a web, the winding assembly can perform high-volume, streaming production of wound web rolls. | 12-23-2010 |
| 20100320302 | In-Line Formed Core Supporting a Wound Web - A web is wound onto an in-line core instead of a separate core. At the start of the winding process, a core-forming substrate attached to the leading edge of the web is wound into an in-line core. The web is wound around the in-line core. For streaming operation, a composite substrate-web stream comprising an alternating sequence of attached core-forming substrate segments and web segments is produced. The first core-forming substrate segment is wound into a first in-line core, and the first web segment is wound around the first in-line core. The composite substrate-web stream is cut. The second core-forming substrate segment is wound into a second in-line core, and the second web segment is wound around the second in-line core. The composite substrate-web stream can be slit longitudinally to produce multiple composite substrate-web stream strips. Multiple composite substrate-web stream strips can be wound in parallel on a single mandrel. | 12-23-2010 |
