Abstract
The present invention relates to a process for laminating components with sheets, in which an adhesive is applied to the surface of the laminating sheet and/or of the component in a grid-like manner, so that, after the sheet and the component are joined, the adhesive is arranged between the sheet and the component, and the regions between the applied adhesive form a channel system that enables the removal of the air that is present between the component and the sheet. The invention further relates to a laminated molded part obtainable by the above-outlined process. The use of an adhesive grid provided between a component and a laminating sheet results in a reduction or prevention of air inclusions when the component is laminated with a laminating sheet.
Claims16
A process for preparing a laminated molded part from a component and a laminating sheet, comprising:
- applying an adhesive in a grid-like manner to a surface of at least one of the laminating sheet and the component, wherein channels are formed on the surface from the grid-like application of the adhesive;
- joining the component and the laminating sheet in such a way that the layer of the adhesive applied in a grid-like manner is arranged between the laminating sheet and the component;
- and
- bonding the laminating sheet with the component by extracting air present between the component and the laminating sheet through the channels by applying a reduced pressure between the component and the laminating sheet.
-15. (canceled)
The process according to claim 11, wherein the step of applying the adhesive includes applying the adhesive as dots or stripes in a form selected from truncated-pyramid-shaped, polygonal, diamond-shaped, rectangular, oval, L-shaped, round and irregularly-shaped adhesive deposits.
