Method for producing at least two-layer components, and component
View Patent ↗The invention relates to a method for producing at least two-layer components and correspondingly produced components per se as absorptive lining in the interior and/or boot or for floor coverings of motor vehicles, comprising a top material and an absorber.
1. A method for producing at least two-layer components as an absorptive lining in the interior and/or trunk or for floor coverings of motor vehicles, comprising a top material and an absorber, characterized in that:
(a) an absorber material molded on one side in a flock box is introduced into a steam/vacuum mold;
(b) the top material cut into blanks is introduced into the mold with its flow-closed side facing towards the material of the absorber, which contains a binder, according to step (a);
(c) the mold is closed;
(d) by applying steam from the lower side of the bottom material, the top material is deformed, the binder in the bottom material is activated, and the top and bottom materials are bonded to one another;
(e) the steam pressure is reduced by a lower pressure on the upper side as compared to the pressure on the lower side of the bottom material; and
(f) the component is subsequently cooled in a calibrating mold or deposit tray.
2. The method according to claim 1 , characterized in that said top material is in a cold or heated state when introduced into said mold.
3. The method according to claim 1 , characterized in that said introducing of the top material into the mold is effected by means of a tenter device that is provided outside the mold.
4. The method according to claim 1 , characterized in that a textile top material is employed, optionally with a mixed fiber web or a recycling sandwich web.
