Abstract: Coils for use as cushioning, such as dunnage, made from spiral coils of paper that are recyclable and biodegradable, or from other thin, flexible, resilient strips. The coils are cylindrical or cylindrical with a transverse fold, and when used as dunnage are randomly oriented to provide cushioning for packaged articles.
Abstract: Apparatus and methods for making improved dunnage from a length of flexible material, such as paper. Strips are formed from the material and modified to form spiral coils by feeding the strips between a fixed rigid forming blade and a rotated roller having a resilient surface. The roller carries peripherally spaced cutting blades that act against the forming blade to periodically sever coiled portions of the strips. The coils are preferably then creased between their ends and are randomly oriented in a container to provide cushioning for packaged articles. The coils are formed at the time of use by the apparatus and methods disclosed.
Abstract: Improved dunnage made from spiral coils of paper that are recyclable and biodegradable, or from other thin, flexible, resilient strips. The coils are cylindrical or cylindrical with a transverse fold, and are randomly oriented in a container to provide cushioning for packaged articles. The coils are formed at the time of use by modifying the material used to cause it to coil and forming strips from the material. This eliminates the need for storage of bulky dunnage. Paper used to form the coils is stretched to cause it to coil. Apparatus concurrently forms plural coils from a web.
