Abstract

Claims (21)

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

a first roller connected to a drive mechanism;

a pinch element disposed adjacent the first roller wherein the sheeting material travels between the first roller and the pinch element, and further wherein the pinch element pushes the sheeting material against the first roller to engage the sheeting material with the first roller; and

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

2. The apparatus of claim 1 , wherein the first roller and pinch element 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 the pinch element away from the first roller.

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

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

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

7. The apparatus of claim 5 , further comprising:

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

the pivotable door interconnected with the first arm at the pivot point, wherein upward pressure on the guide element causes tension applied against the first roller by the pinch element to increase.

8. The apparatus of claim 7 , wherein the guide element comprises another roller.

9. The apparatus of claim 5 , wherein the pinch element comprises a pinch roller.

10. The apparatus of claim 1 , further comprising a neck at disposed for feeding the sheeting material to the first roller and pinch element and configured for reducing the lateral width of sheeting material fed to the first roller and pinch element.

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

12. The apparatus of claim 11 , wherein the tines are arranged to define an imaginary surface disposed over the tines, over which the sheeting material is directed, that is curved laterally and longitudinally.

13. The apparatus of claim 1 , wherein:

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

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

14. The apparatus of claim 13 , further comprising a cutting mechanism configured for cutting the crumpled sheeting material.
