Abstract

A device for driving fastening elements into a substrate comprises a setting channel; an energy transmission element, which can be moved in a fastening direction in the setting channel, for transmitting energy to one of the fastening elements at a time; and a magazine for transporting the fastening elements to the setting channel in a transport direction. The magazine is suitable for transporting multiple rows of fastening elements at once. Additionally, a fastening element strip comprises a plurality of rows of receptacles for fastening elements aligned in a transport direction and fastening elements which are housed in the receptacles and define a fastening direction, wherein the rows of receptacles are arranged one behind the other in a transverse direction oriented perpendicular to the transport direction and perpendicular to the fastening direction.

First claim

The invention claimed is:

1. A fastening element strip, having a plurality of rows of receptacles for fastening elements, oriented in a transport direction, and fastening elements which are received in the receptacles and which define a fastening direction, wherein the rows of receptacles are arranged one behind the other in a transverse direction which is perpendicular to the transport direction and perpendicular to the fastening direction, and having a connecting web which connects a receptacle of a first row of the plurality of rows to a receptacle of a second row of the plurality of rows.

2. The fastening element strip according to claim 1 , wherein each receptacle is offset in the transport direction relative to all other receptacles of the plurality of rows of receptacles.

3. The fastening element strip according to claim 2 , wherein the offset measured in the transport direction between two receptacles which are adjacent in the transport direction is substantially the same for all receptacles.

4. The fastening element strip according to claim 1 , wherein each receptacle of the first row is directly connected to an adjacent receptacle of a second row via a connecting web.

5. The fastening element strip according to claim 1 , wherein the connecting web has a predetermined breaking point for separating at least one of the receptacles in an apparatus for driving fastening elements into a substrate, the apparatus comprising a setting channel; an energy transmitting element which can move in the setting channel in a fastening direction to transmit energy to each of the fastening elements; and a magazine for transporting the fastening elements to the setting channel in a transport direction, wherein the magazine is suitable for transporting, at the same time, a plurality of rows of fastening elements arranged one behind the other in a transverse direction oriented perpendicular to the transport direction and perpendicular to the fastening direction, to alternately transport fastening elements of different rows of the plurality of fastening element rows into the setting channel.

6. The fastening element strip according to claim 1 , wherein the fastening element strip has a support projection with a contact surface for the fastening element strip to contact a guide channel of a magazine of an apparatus for driving fastening elements into a substrate, the apparatus comprising a setting channel; an energy transmitting element which can move in the setting channel in a fastening direction to transmit energy to each of the fastening elements; and a magazine for transporting the fastening elements to the setting channel in a transport direction, wherein the magazine is suitable for transporting, at the same time, a plurality of rows of fastening elements arranged one behind the other in a transverse direction oriented perpendicular to the transport direction and perpendicular to the fastening direction, to alternately transport fastening elements of different rows of the plurality of fastening element rows into the setting channel, wherein the support projection protrudes from a receptacle of an outermost row of the plurality of rows and is offset in the transport direction from a fastening element received in the receptacle.
