Zusammenfassung:An apparatus and method for aligning a continuous web of material with an entry point of a machine that utilizes the web as a source material. The web may include pre-processed materials that may be thicker than conventional webs and/or have uneven thickness, and/or are susceptible to excessive compression forces and/or tensions which may be found in ordinary straight-wound rolls. Such pre-processed materials may be wound in traverse-wound rolls or festooned into a container forming a web source structure which is wider than the web width. The web is pulled from such web source structure by the machine through a series of guides which include surfaces having various properties and shapes to create tensions in the web and to align the web with the entry point of the machine.
