Abstract

A strapped fastener assemblage for an automatic fastener driver includes a pair of connecting straps made of paper, each of which has a plastic film laminated onto one surface of the connecting strap. The plastic-film-side surfaces of the connecting straps are in contact with each other. A plurality of pin-like fasteners are arranged in parallel to one another with a predetermined spacing and each of the fasteners extend transversely of and between the connecting straps; and a plurality of fastener retainers are defined by a pair of heat-sealed portions in the connecting straps extending transversely of the connecting straps, and the fastener retainer will retain a corresponding one of the fasteners.

Claims

1. A strapped fastener assemblage, comprising:

a pair of connecting straps made of paper, a plastic film is laminated onto one surface of each of the connecting straps, the plastic-film-side surfaces of the connecting straps being in contact with each other;

a plurality of pin-like fasteners arranged generally parallel to one another with a predetermined spacing therebetween, each of said fasteners extending transversely of and between the connecting straps;

a plurality of fastener retainers each of which is defined by a pair of heat-sealed portions of the connecting straps extending transversely of the connecting straps, said fastener retainer retaining a corresponding one of said fasteners; and

separation means provided on only one connecting strap of each fastener retainer for facilitating removal of the pin-like fastener from the fastener retainer.

2. The strapped fastener assemblage as set forth in claim 1, wherein the pin-like fasteners are nails.

3. The strapped fastener assemblage as set forth in claim 1, wherein each of said plurality of fastener retainers are tubular, said portions of the connecting straps defining the fastener retainers each being generally cylindrical and said separation means for each fastener retainer being located on one semicylindrical connecting strap of the pair of connecting straps defining that fastener retainer.

4. The strapped fastener assemblage as set forth in claim 1, wherein said separation means comprises sewing perforations extending transversely of the one connecting strap.

5. The strapped fastener assemblage as set forth in claim 4, wherein the sewing perforations extend between each edge of the one connecting strap.

6. The strapped fastener assemblage as set forth in claim 1, wherein a transverse width is generally the same for each of the connecting straps.

7. The strapped fastener assemblage as set forth in claim 4, wherein each of the pin-like fasteners has a head and an elongated portion, and wherein only one of the pair of connecting straps extends over at least the heads of each of the pin-like fasteners.

8. The strapped fastener assemblage as set forth in claim 7, wherein the connecting strap extending over the heads of each of the pin-like fasteners is different from the connecting strap having the separation means.

9. The strapped fastener assemblage as set forth in claim 1, wherein each of the pin-like fasteners has a head and an elongated portion, and wherein only one of the pair of connecting straps extends over at least the heads of each of the pin-like fasteners.

10. The strapped fastener assemblage as set forth in claim 9, wherein the connecting strap extending over the heads of each of the pin-like fasteners is different from the connecting strap having the separation means.

11. The strapped fastener assemblage as set forth in claim 1, wherein said separation means comprises at least one slot extending transversely of the one connecting strap for each of the fastener retainers.

12. The strapped fastener assemblage as set forth in claim 11, wherein each of the slots is provided between edges of the one connecting strap.

13. The strapped fastener assemblage as set forth in claim 11, wherein two slots are provided for each fastener retainer, said two slots being opposed and being located at edges of the one connecting strap.

14. The strapped fastener assemblage as set forth in claim 13, wherein each slot is generally V-shaped.

15. The strapped fastener assemblage as set forth in claim 14, wherein each slot is generally U-shaped.

16. The strapped fastener assemblage as set forth in claim 1, wherein the pin-like fasteners are screws.
