  • OFF-SET GEARS AND METHODS OF USING OFF-SET GEARS FOR PRODUCING CUSHIONING MATERIAL
    Publication number: 20140162012
    Abstract: Some embodiments of the present invention comprise an off-set gear assembly for use in producing cushioning material and methods for using the same. Each gear of the off-set gear assembly has at least two sections. Each section includes a set of gear teeth. The gear teeth of the two sections can be rotationally off-set and this can result in the production of cushioning material with staggered ridges. Some embodiments of the present invention also comprising cushioning material with staggered ridges.
