Title: Process and apparatus for producing vehicle interior linings or the like from multi-component plastics
Inventor: REISINGER GERHARD
IPC: B29C44/12
Filed: 1993-05-18
Abstract: The process according to the invention for producing vehicle interior linings is preferably carried out in an open mould (2, 3). A support part (1), produced in advance, is fastened on the upper mould half. Then the top layer of material is sprayed into the other, lower mould half (3). After reacting of the top layer (5) is complete, the multi-component material is filled onto the top layer. During closing of the mould, the top film is sheared off at its edge (5a) and the remaining edge is bent around inwards before the foaming of the multi-component plastic. The adhesive bonding between bent-around top layer and support part is performed with the aid of the foaming multi-component plastic material. The finished part, produced virtually in one operation, can then be removed. Thus, the trimming and bending around take place in one operation in the mould in which the foam-backing also takes place. <IMAGE>
