Method for producing a component provided with a multipart cover layer and said component
First Claim
1. A method for a production of a component in a tool having a cavity-forming first tool half and a second tool half including at least a first channel and a second channel, comprising:
- a) inserting at least a first skin and a second skin into the second tool half such that the first skin and the second skin overlap in their end regions and such that the first channel and the second channel of the second tool half lie across from the overlap, wherein the second skin comprises an externally situated end region, which includes at least one skin opening;
b) one of rear-foaming and rear-spraying of the first skin and the second skin with one of a foam material and a spraying material,c) exerting a first low pressure in a region of the at least one skin opening through the first channel to pressure an internally situated end region of the first skin against the externally situated end region of the second skin in one of a foam-tight manner and an injection moulding-tight manner; and
d) exerting a second low pressure in an edge region between an edge of the externally situated end region and the internally situated end region through the second channel.

Abstract
A component is produced according to the following steps: a) insertion at least of two skins into the second tool half of a tool having a cavity-forming first tool half and second tool half such that the skins overlap in their end regions; b) rear-foaming or rear-spraying of the skins with a foam material or spraying material, c) by exerting low pressure in the region of the overlap, the internally situated end region of the one skin being pressed against the externally situated end region of the other skin in a foam-tight or injection molding-tight manner.

13. A method for a production of a component in a tool having a cavity-forming first tool half and a second tool half including at least a first channel and a second channel, comprising:
-
a) inserting at least a first thermoplastic skin and a second thermoplastic skin into the second tool half such that the first thermoplastic skin and the second thermoplastic skin overlap in their end regions and such that the first channel and second channel of the second tool half lie across from the overlap; b) one of rear-foaming and rear-spraying of the first thermoplastic skin and the second thermoplastic skin with one of a foam material and a spraying material; and c) exerting a low pressure in a region of the at least one skin opening through the first channel to pressure an internally situated end region of the first thermoplastic skin against the externally situated end region of the second thermoplastic skin in one of a foam-tight manner and an injection molding-tight manner, where the internally situated end region and the externally situated end region are attached to each other by heating the second tool half. - View Dependent Claims (14)
