  • Patent number: 5910079
    Abstract: A method and apparatus for manufacturing paper cushioning members in which work paper is inserted between a pair of intermittent-cutting roller members to process multiple rows of thin bands with link portion. Waste-collecting members are provided at a discharge side of the rollers to separate the work paper from the roller members and to feed the processed work paper into a wave-forming guide. The wave-forming guide includes an upper pressing member that rotates about a hinge positioned at an end nearest to the discharge side of the rollers and a counterweight positioned at a distal end of said upper pressing member such that the upper pressing member is biased toward the interior of the wave-forming guide. The wave-forming guide is designed to forcibly compress the processed work paper into finely crumpled thin bands and to discharge the crumpled thin bands in a wavy form.
