Abstract (en)
[origin: WO9507225A2] An expanded paper cylinder formed from a spiral is disclosed as a void fill. A delivery system is provided for manual and automatic delivery of the expanded paper from a continuous, unextended wound roll of an extendible sheet material. The cushioning material formed by the expander can be used as an expanded sheet around an article or as void fill, or can be formed into spiral cylinders for use as void fill. The manual dispensing system includes a support member supporting a rotatable feed roll. A restraining device slows the free delivery of the wound feed roll of unextended sheet material, so that the sheet material expands while it is being drawn, under tension from the feed roll. An automatic system uses expander rollers to expand the slit paper and can be coordinated with apparatus which cuts and forms the spiral cylinders.
