ABSTRACT:
A machine for forming a packing material by positioning a paper material on or adjacent to a die member and forcing a multitude of cutting blades completely through the paper material and into the die member at a multitude of spaced apart locations to form a multitude of slits in the paper material. These slits allow the paper material to be pulled or expanded into a three dimensional shape that is both load bearing and resilient. In a first embodiment, the forming of the packing material is carried out in a flat die press, including upper and lower die members and with the cutting blades secured to the upper die member. In a second embodiment, the forming of the packing material is carried out in a rotary press including upper and lower rotatable rollers and with the cutting blades secured to the upper roller.
