Abstract
A device for manufacturing inner trim elements which are formed by a rigid carrier and a cover layer, between which elements a polymer foam layer is arranged. The carrier is fixable on a first molding tool element, and the cover layer is fixable between the outer edge of the first molding tool element and the outer edge of a second molding tool element. In the molding tool, a cavity is formed between the carrier and the cover layer, wherein a foamable polymer is introducible into the cavity via at least one through-hole which is formed in the carrier and the first molding tool element. The distance between the first and the second molding tool element is enlargeable during the foaming process. At least one through-hole for an escape of air and reactively formed gases out of the cavity is formed in the carrier and in the first molding tool element.
