Abstract
Disclosed is a method for producing a strip for fastening elements, said strip comprising a plurality of interconnected holders, each of which accommodates a shaft of a fastening element. The holders define a fastening direction in which the fastening element can be driven from the holder into a support by a fastening device. The disclosed method comprises the following steps: a) producing a continuous strip defining a longitudinal direction of the strip; b) making the holders from the strip material by means of a deep-drawing process; c) accommodating the fastening elements in the holders.
Claims14
Method for the production of a strip for fastening elements with a plurality of interconnected holders for a shaft of a fastening element, wherein the holders define a fastening direction, in which the fastening element can be driven by a fastening device from the holder into a support, wherein the method comprises the following steps:
- a) production of a continuous strip, which defines a longitudinal direction of a strip;
- b) production of the holders from the material of the strip;
- c) incorporation of the fastening elements into the holders,
- wherein during step b), the holders are produced by a deep-drawing process, transverse to the fastening direction.
Method according to one of the preceding claims, wherein the deep-drawing process takes place perpendicular to the longitudinal direction of the strip.
Method according to one of the preceding claims, wherein during step b), that strip material which forms a holder leaves behind an opening in the strip.
Method according to one of the preceding claims, wherein during or after step b), the holders are provided with a slit, which extends, in particular, along the fastening direction.
Method according to one of the preceding claims, wherein during step c), the fastening elements are snapped into the holder, in particular, through the pertinent slit.
Method according to one of the preceding claims, wherein during step c), the fastening elements in the fastening direction are introduced into the holder, in particular, are inserted or screwed in.
Method according to one of the preceding claims, wherein the shaft has a thread, which is suitable, in particular, for cutting a counter-thread into the holder, if the fastening element is incorporated into the holder or is driven from the holder into the support.
Method according to one of the preceding claims, wherein during or after step b), the holders are provided with a predetermined breaking point, which extends, in particular, along the fastening direction.
Method according to one of the preceding claims, wherein the fastening element has a head on the end of the shaft, contrary to the fastening direction, and a funnel-shaped, in particular, conical expansion section between the head and the shaft, whose outside dimensions, transverse to the fastening direction, exceed the inside dimensions of the holder.
Method according to one of the preceding claims, wherein the holder can be expanded, in particular, can be bent open, through the head or the expansion section with the movement of the fastening element in the fastening direction.
