Problems solved by technology

[0013] The ever-new and complexly designed functional assemblies, especially in the interior of motor vehicles, make the production of suitably shaped heating channel units or channels considerably more difficult, thereby making the production of the associated channeling units more and more complicated. ground design
This results in significant additional costs when providing bending equipment

Embodiment Construction

[0078] according to figure 1 and 2 The illustration of the channel 3 of the heating channel unit shows the presence of the bending device 2 which is not further shown here figure 1 The heating channel unit 1 shown in , wherein the bending device is used to bend the edge of the decorative layer around the carrier, and the channel is used to guide air heated at an air heater (not shown) or hot air (not shown here) marked in detail).

[0079] The channel 3 is substantially U-shaped and here has a contour that is three-dimensionally multiple times in space over the longitudinal extension 6 of the channel 3 from the first end 4 of the channel 3 to the second end 5 of the channel 3 bent, if able to figure 2 as seen in the .

[0080] At this point, the channels 3 of the heating unit 1 already have a somewhat complexly shaped channel course.

[0081] This channel 3 is thus an essential part 7 of the heating channel unit 1 .

[0082] as in the same figure 2 As can be clearly s...

Abstract

To simplify a structure and a method in a complex geometrical outline, the invention accurately provides a heating channel unit for a folding device. The invention provides a heating channel unit of a folding device for folding a border of a decorative layer about a carrier part, which 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.

Description

technical field [0001] The invention relates to a heating channel unit for a bending device for bending the edge of a decorative layer around a carrier, having a channel and a plurality of outlets leading from the channel. [0002] The invention also relates to a method for producing a heating channel unit for heating the edge of a decorative layer, wherein the channels of the heating channel unit are provided with a plurality of outlets for the discharge of hot air. [0003] The invention also relates to a bending device for bending a decorative layer edge around a carrier, having a heating channel unit for heating the decorative layer edge. Background technique [0004] Bending devices of this type with a heating channel unit for heating at least one edge region of the decorative layer have long been known in the prior art, for example from the automotive industry. [0005] In the adhesive bending process, for example for bending the edges of decorative layers for automot...
