Abstract

The invention is directed to a nail driving device, comprising a driving ram having a drive unit and a feed mechanism for a nail strip that is transportable in a transporting direction, wherein a guide member and/or a transporting member of the feed mechanism acts in operation on the receiving ribbon. It is proposed that the guide member and/or transporting member is formed to operate on receiving ribbons of different widths.

First claim

The invention claimed is:

1. A nail driving device, comprising a driving ram having a drive unit and a feed mechanism for a nail strip that is transportable in a transporting direction,
wherein the nail strip comprises a receiving ribbon of a first type, which holds nails and has a first width measured in a driving direction of the nails, and
wherein a guide member and/or a transporting member of the feed mechanism acts in operation on the receiving ribbon,
wherein
the guide member and/or transporting member is additionally formed to act during operation on a nail strip having a receiving ribbon of a second type, wherein a width of the receiving ribbon of the second type has a second defined width which is different from the first width, wherein, in operation, top edges of the receiving ribbons of the first type and the second type are in different positions in the feed mechanism with respect to the driving direction,
the transporting member comprises a driver that is moved in the transporting direction,
the driver has a first driver claw and at least one second driver claw, wherein in particular the driver claws are spaced apart in a width direction, and
the receiving ribbons have transporting openings, wherein both driver claws engage in the transporting opening of the receiving ribbon of the first type, and wherein only one of the driver claws engages in the transporting opening of the receiving ribbon of the second type.

2. The nail driving device as claimed in claim 1 , wherein bottom edges of the receiving ribbons of the first type and the second type are in identical positions with respect to the driving direction.

3. The nail driving device as claimed in claim 1 , wherein the second width is at least 20%, smaller or larger than the first width.

4. The nail driving device as claimed in claim 1 , wherein the guide member comprises a mask extending in particular transversely to the transporting direction, preferably in that the receiving ribbon emerges without held nails from the mask downstream of a driving position in the transporting direction.

5. The nail driving device as claimed in claim 4 , wherein a first mask opening serves only for guiding the receiving ribbon of the first type and a second mask opening serves only for guiding the receiving ribbon of the second type.

6. The nail driving device as claimed in claim 5 , wherein the first mask opening and second mask opening, preferably together with at least a portion of a third mask opening, form substantially L-shaped mask opening regions of the first type and second type for the emergence of the receiving ribbons corresponding to the first type and second type.

7. The nail driving device as claimed in claim 6 , wherein the receiving ribbons of the first type and second type are in substantially form-fitting engagement with the corresponding L-shaped mask opening region.

8. The nail driving device as claimed in claim 6 , wherein the L-shaped mask opening regions each have a limb extending substantially parallel to the driving direction, the length of said limb corresponding substantially to the length of the limb, that emerges there, of the associated receiving ribbon.

9. The nail driving device as claimed in claim 4 , wherein the receiving ribbons each comprise a central part having laterally adjoining bent-up tabs for holding the nails.

10. The nail driving device as claimed in claim 1 , wherein the driver is formed in an elastically resilient manner at least during a part of its movement.

11. The nail driving device as claimed in claim 1 , wherein the second width is at least 30% smaller or larger than the first width.

12. An assembly, comprising:
a nail driving device, including:
a driving ram having a drive unit and a feed mechanism for a nail strip that is transportable in a transporting direction, wherein the nail strip comprises a receiving ribbon of a first type, which holds nails and has a first width measured in a driving direction of the nails, and wherein the nail driving device is configured to receive the receiving ribbon of the first type,

wherein the feed mechanism includes a guide member and a transporting member, and
wherein at least one of the guide member or the transporting member is configured to act in operation on the receiving ribbon,

wherein
at least one of the guide member or the transporting member is further configured to act during operation on a nail strip having a receiving ribbon of a second type, wherein a width of the receiving ribbon of the second type has a second defined width which is different from the first width, wherein, the nail driving device is configured such that, in operation, top edges of the receiving ribbons of the first type and the second type are in different positions in the feed mechanism with respect to the driving direction,
the transporting member comprises a driver that is moved in the transporting direction,
the driver has a first driver claw and at least one second driver claw, wherein in particular the driver claws are spaced apart in a width direction, and
the receiving ribbons have transporting openings, wherein both driver claws engage in the transporting opening of the receiving ribbon of the first type, and wherein only one of the driver claws engages in the transporting opening of the receiving ribbon of the second type.

13. The assembly of claim 12 , further comprising:
the receiving ribbon of the second type, wherein the receiving ribbon of the second type is loaded into the nail driving device and is interfacing with at least one of guide member or the transporting member.

14. The assembly as claimed in claim 13 , wherein bottom edges of the receiving ribbons of the first type and the second type are in identical positions with respect to the driving direction.

15. The assembly as claimed in claim 13 , wherein the second width is at least 20%-smaller or larger than the first width.

16. The assembly as claimed in claim 13 , wherein the guide member comprises a mask extending in transversely to the transporting direction, and is configured such that the receiving ribbon emerges without held nails from the mask downstream of a driving position in the transporting direction during operation.

17. The assembly claimed in claim 16 wherein a first mask opening serves only for guiding the receiving ribbon of the first type and a second mask opening serves only for guiding the receiving ribbon of the second type.

18. The assembly as claimed in claim 17 , wherein the first mask opening and second mask opening, preferably together with at least a portion of a third mask opening, form substantially L-shaped mask opening regions of the first type and second type for the emergence of the receiving ribbons corresponding to the first type and second type.

19. The assembly as claimed in claim 17 , wherein the receiving ribbons of the first type and second type are in substantially form-fitting engagement with the corresponding L-shaped mask opening region.

20. The assembly as claimed in claim 17 , wherein the L-shaped mask opening regions each have a limb extending substantially parallel to the driving direction, the length of said limb corresponding substantially to the length of the limb, that emerges there, of the associated receiving ribbon.

21. The assembly as claimed in claim 16 , wherein the receiving ribbons each comprise a central part having laterally adjoining bent-up tabs for holding the nails.

22. The assembly as claimed in c
