Abstract

Claims (19)

1. An apparatus for converting sheeting material for making a cushioning product, comprising:

a first roller connected to a drive mechanism;

a second roller disposed adjacent said first roller wherein said sheeting material travels between the first roller and the second roller and further wherein the second roller pushes said sheeting material against said first roller to engage the sheeting material with the first roller; and

a magnet having a magnetic force for holding said second roller adjacent said first roller, the magnet and second roller being configured for allowing the second roller to automatically move away from said first roller to disengage the sheeting material from the first roller when the sheeting material overloads between the first roller and second roller and creates a force that exceeds a magnetic force of the magnet.

2. The apparatus of claim 1 , wherein the first and second rollers are associated to engage the sheeting material and convert the sheeting material for making the cushioning product.

3. The apparatus of claim 1 , further comprising a handle which assists in moving said second roller away from said first roller.

4. The apparatus of claim 1 , wherein said second roller is configured for changing the tension applied to the sheeting material as the sheeting material travels between the first roller and the second roller.

5. The apparatus of claim 1 , further comprising a first arm attached to a pivot point wherein said second roller is attached to said arm, wherein said second roller is magnetically held adjacent said first roller.

6. The apparatus of claim 5 , further comprising a second arm attached to said pivot point wherein said first arm is magnetically held to said second arm for holding said second roller adjacent said first roller.

7. The apparatus of claim 5 , further comprising:

a pivotable door attached to said pivot point and a third roller attached to said pivotable door, said first arm magnetically held to said pivotable door for holding said second roller adjacent said first roller, wherein said sheeting material traverses under said third roller causing upward pressure on said third roller; and

said pivotable door interconnected with said first arm at said pivot point, wherein upward pressure on said third roller causes tension applied against said first roller by said second roller to increase.

8. The apparatus of claim 1 , further comprising a neck at disposed for feeding the sheeting material to the first and second rollers and configured reducing the lateral width of sheeting material fed to the first and second rollers.

9. The apparatus of claim 1 , wherein the feeder comprises a guide having a plurality of longitudinally disposed tines for guiding said sheeting material and disposing a wave pattern in said sheeting material, wherein the tines are curved longitudinally.

10. The apparatus of claim 9 , wherein the tines are arranged to define an imaginary surface disposed over said tines, over which the sheeting material is directed, that is curved laterally and longitudinally.

11. The apparatus of claim 1 , wherein:

the apparatus is a crumpling apparatus configured for crumpling the sheeting material for making the cushioning product;

the first and second rollers are disposed in a crumpling zone configured to crumple the sheeting material, the first roller comprising a drive roller, and the second roller comprising a pinch roller, the drive roller and pinch roller associated for cooperatively pulling and crumpling the sheeting material.

12. The apparatus of claim 11 , further comprising a cutting mechanism configured for cutting the crumpled sheeting material.
