Abstract

A heating channel unit of a folding device for folding a border of a decorative layer about a carrier part, includes a channel and a plurality of outlets from the channel, with at least a portion of the heating channel unit being produced via an additive production method.

First claim

1 . A heating channel unit of a folding device for folding a border of a decorative layer about a carrier part, comprising a channel and a plurality of outlets from said channel, wherein at least a portion of the heating channel unit is produced via an additive production method.

2 . A heating channel unit according to claim 1 , wherein at least a portion of the heating channel unit is produced in a 3D-printing method.

3 . A heating channel unit according to claim 1 , wherein at least a portion of the channel is produced via an additive production method.

4 . A heating channel unit according to claim 1 , wherein at least a portion of the outlet is provided via an additive production method.

5 . A heating channel unit according to claim 1 , wherein a plurality of hot air guiding elements configured for conducting hot air are produced at least partially via an additive production method.

6 . A heating channel unit according to one of the previous claim 1 , wherein a plurality of shoulder elements projecting from the channel towards the outside are provided for limiting the heated space between the channel and the border of the decorative layer, at least partially via an additive production process.

7 . A heating channel unit according to claim 1 , wherein a plurality of connection tube elements for introducing hot air into the channel are produced at least partially via an additive production method.

8 . A heating channel unit according to claim 1 , wherein a plurality of opening transitions are embodied like funnels between the connection tube elements and the channel.

9 . A heating channel unit according to claim 1 , wherein the channel, the outlets, and/or the connection tube elements each show different cross-sections, which are produced via an additive production method, particularly in the 3D-printing method.

10 . A heating channel unit according to claim 1 , wherein the channel, the outlets, the hot air guiding elements, the connection tube elements, and/or the laterally projecting shoulder elements are produced at least partially in one piece.

11 . A heating channel unit according to one of the previous claims 1 , wherein the heating channel unit is assembled from a plurality of parts.

12 . A method for the production of a heating channel unit for heating a border of a decorative layer, in which a channel of the heating channel unit is adjusted to a contour of a carrier part to be provided with a decorative layer, wherein the channel is produced in a generative fashion in order to adjust the channel to the progression of the contour of the carrier part.

13 . A method according to claim 12 , wherein the channel and a plurality of outlets arranged therein configured for hot air exiting are generated jointly in a generative fashion.

14 . A method according to claim 12 , wherein the heating channel unit is produced at least partially based on a single data set.

15 . A folding device for folding a border of a decorative layer about a carrier part comprising a heating channel unit for heating the border of the decorative layer, wherein a heating channel unit configured for heating the border of the decorative layer according to claim 1 .
