Abstract

The invention relates to a method for introducing a media outlet (6) into a hollow profiled section (1), in which method a first media outlet passage (7), via which a medium can flow out of a cavity (2) in the hollow profiled section (1), is introduced by means of a first tool into an outer wall (5) of the hollow profiled section (1), and in which method a second tool is introduced into the cavity (2) in the hollow profiled section (1) via the first media outlet passage (7), and by means of said second tool at least one second media outlet passage (8) is introduced into an inner profiled section web (4) of the hollow profiled section (1). The invention further relates to a method for providing a hollow profiled section (1), in which the hollow profiled section (1) is extruded and a media passage (6) is introduced into the hollow profiled section (1) in a method according to any of the preceding claims, a geometry of the profiled section web (4) being selected depending on a position of the first media outlet passage (7) and the hollow profiled section (1) being extruded with the selected geometry of the profiled section web (4).

First claim

What is claimed is:

1. A method for forming a media outlet in a hollow profile, comprising:
forming a first media-outlet passage in an outer wall of the hollow profile with a first tool, wherein a medium can flow out of a cavity of the hollow profile via the first media-outlet passage, and
introducing a second tool into the cavity of the hollow profile via the first media-outlet passage, wherein at least one second media-outlet passage is formed in an inner profile web of the hollow profile by the second tool.

2. The method according to claim 1 , wherein
the first media-outlet passage is formed in the outer wall in a lowermost region of the outer wall, and wherein
the at least one second media-outlet passage is formed in the profile web in a lowermost region of the profile web.

3. The method according to claim 1 , wherein
the first media-outlet passage and the at least one second media-outlet passage are formed in the hollow profile with their respective central axes oblique to one another.

4. The method according to claim 1 , wherein the at least one second media-outlet passage is formed in the profile web with a smaller cross section than a cross section of the first media-outlet passage in the outer wall.

5. The method according to claim 1 , wherein multiple second media-outlet passages are formed in the profile web.

6. The method according to claim 1 , wherein the at least one second media-outlet passage is formed in the profile web via four-axis machining or five-axis machining with the second tool.

7. The method according to claim 1 , wherein a cross section of the first media-outlet passage is selected according to a tool geometry of the second tool and/or a relative position of the first media-outlet passage with respect to the at least one second media-outlet passage.

8. The method according to claim 1 , further comprising: extruding the hollow profile, wherein a geometry of the profile web is selected according to a position of the first media-outlet passage and the hollow profile is extruded with the selected geometry of the profile web.
