IN-LINE FORMED CORE SUPPORTING A WOUND WEB

摘要

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.
