Abstract

A method for penetrating a material with a fastener dispensing needle includes the steps of partially penetrating the material using a first penetration stroke, partially withdrawing the needle from the material using a first withdrawal stroke and, in turn, fully penetrating the material using a second penetration stroke. Once fully penetrated, a plastic fastener is dispensed from the fastener dispensing needle. Thereafter, the fastener dispensing needle is fully withdrawn from the material. Additional partial penetration and withdrawal strokes could be incorporated into the needle penetration cycle in a repeating pattern, as needed, with each penetration stroke preferably having a stroke length which is twice the length of each withdrawal stroke. The use of an oscillating, back-and-forth, linear needle penetration cycle serves to minimize the risk of lateral needle deflection which can result in bending or breakage of the needle as well as damage to the penetrated material.

First claim

What is claimed is:

1. A method for penetrating a material with a fastener dispensing needle, the material having a first surface and an opposing second surface, the fastener dispensing needle having a leading end with a sharpened tip, the method comprising the steps of:
(a) partially penetrating the material with the fastener dispensing needle using a first penetration stroke;
(b) after the partial penetration step, partially withdrawing the fastener dispensing needle from the material using a first withdrawal stroke; and
(c) after the partial withdrawal step, fully penetrating the material with the fastener dispensing needle using a second penetration stroke.

2. The method as claimed in claim 1 wherein the first penetration stroke extends from the first surface of the material to a first location in the material between the first surface and the second surface.

3. The method as claimed in claim 2 wherein the first withdrawal stroke extends from the first location in the material to a second location in the material between the first surface and the first location.

4. The method as claimed in claim 3 wherein the second penetration stroke extends from the second location in the material to beyond the second surface.

5. The method as claimed in claim 1 further comprising the step of, between the partial withdrawal step using the first withdrawal stroke and the full penetration step using the second penetrations stroke, partially penetrating the material with the fastener dispensing needle using a third penetration stroke.

6. The method as claimed in claim 5 further comprising the step of, between the partial penetration step using the third penetration stroke and the full penetration step using the second penetration stroke, partially withdrawing the fastener dispensing needle from the material using a second withdrawal stroke.

7. The method as claimed in claim 6 wherein the full penetration step occurs immediately after the partial withdrawal step using a second withdrawal stroke.

8. The method as claimed in 1 wherein each of the first penetration stroke and the first withdrawal stroke has a length, the length of the first penetration stroke being approximately twice the length of the first withdrawal stroke.

9. The method as claimed in claim 8 wherein the first penetration stroke has a length of approximately 0.25 inches.

10. The method as claimed in claim 9 wherein the first withdrawal stroke has a length of approximately 0.12 inches.

11. The method as claimed in claim 1 wherein the fastener dispensing needle penetrates the material during the first penetration stroke along a first linear path.

12. The method as claimed in claim 11 wherein the fastener dispensing needle withdraws from the material during the first withdrawal stroke along the first linear path.

13. The method as claimed in claim 12 wherein the fastener dispensing needle penetrates the material during the second penetration stroke along the first linear path.

14. The method as claimed in claim 1 wherein, after the full penetration stroke, a fastener is dispensed from the fastener dispensing needle.

15. The method as claimed in claim 14 wherein, after the fastener dispensing step, the fastener dispensing needle is fully withdrawn from the material.
