Abstract
Flowable loose packing dunnage is formed from paperboard into three dimensional particles of various shapes. Also, an apparatus for forming the dunnage employs two vertically aligned arrays of toothed, untoothed and/or cutting wheels through the nip of which paperboard segments pass and by which they are shaped into dunnage particles. Further, in a method of forming the dunnage particles, strips of paperboard are cut into segments which are formed into three dimensional shapes. A method of protecting a packed object surrounds it with the flowable loose packing dunnage made of paperboard in accordance with the present invention.
