Abstract

A method for providing a laminate film with adhesive as a step in the preparatory process for manufacturing a laminate mold part using a support part, a method for applying a hot melt to a laminate film, a method for manufacturing a laminate mold part, using a method, a system for laminating a support part as well as a method for such a system produces especially high quality lamination and even if the support part, where the laminate film should be laminated, is not porous by applying the adhesive to the support part for bonding the macroscopically structured laminate film, so that there is a duct system. The air can flow through the duct system between the laminate film and the support part during the lamination process.

First claim

What is claimed is:

1. A method for producing a laminate mold part comprising a vehicle interior panel or a vehicle interior panel part, comprising conducting a preparatory process whereby an adhesive is bonded to a B-side of a laminate film and a support part surface area of a support part by the following steps:
a. applying the adhesive to the B-side;
b. subsequently, reforming the adhesive by embossing it in a grid, so that grid ducts are formed before the adhesive is bonded to the surface of the support part; and
c. producing the laminate mold part.

2. A method for producing a laminate mold part comprising a vehicle interior panel or a vehicle interior panel part, comprising conducting a preparatory process whereby an adhesive is bonded to a B-side of a laminate film and a support part surface area of a support part by the following steps:
a. introducing indentations into the B-side of the laminate film;
b. introducing the adhesive into the indentations and/or between the indentations; and
c. producing the laminate mold part.

3. A method for producing a laminate mold part comprising a vehicle interior panel or a vehicle interior panel part, comprising conducting a preparatory process whereby an adhesive is bonded to a B-side of a laminate film and a support part surface area of a support part by the following steps:
a. applying the adhesive through a slot die;
b. whereby emission of the adhesive is prevented by the slot die through local resistance at an outlet, and thereby forming a grid.

4. The method according to claim 1 , wherein the adhesive is a hot melt is applied to the laminate film.

5. The method according to claim 4 , wherein the hot melt is applied to duct forming structures, so that air from a film surface can be drawn along form ducts between the duct formation surveys.

6. The method in accordance with claim 4 further comprising the following steps:
a. applying a grid-shaped coating of the adhesive to the B-side of the laminate film and/or onto the surface area of the support part, wherein ducts are formed by the grid-shaped coating of the adhesive;
b. bringing together the support part and the laminate film so that a layer of the adhesive applied is arranged between the laminate film and the support part; and
c. connecting the laminate film to the support part by (i) removal of air located between the support part and the laminate film though the ducts by applying a vacuum and/or by (ii) squeezing out the air located between the support part and channels by applying a compacting pressure
wherein
the laminate film is pulled from a roll
and/or
the adhesive is applied around a roller during the circulation of the laminate film
and/or
the adhesive is applied using a slot die on the laminate film
and/or
the adhesive is applied in an internal recess.

7. The method claimed in claim 1 , wherein the laminate film is guided around an embossed roller, wherein the surface of the embossed roller has structured protrusions and is arranged so that a duct pattern is adapted for embossing.

8. The method claimed in claim 1 , wherein the laminate film is guided around an embossed roller, wherein the surface of the embossed roller has structured protrusions and is arranged so that a number of indentations are impressing into the laminate film.

9. The method claimed in claim 1 , wherein the laminate film is guided around a pressure roller and, in one rotation, the pressure roller is guided around to a slot die.

10. The method claimed in claim 1 , wherein the adhesive is introduced into macroscopic indentations of the laminate film.

11. The method claimed in claim 1 , wherein indentations in an initial laminate film are filled with adhesive and then the indentations are flattened, so that the adhesive raises from the indentations, there-by forming a grid-like structure.

12. The method in accordance with claim 11 , wherein to flatten the indentations, the laminate film is actively heated, using lighting with heat lamps.

13. The method in accordance with claim 12 , wherein the indentations are flattened in the laminate film through a memory effect in a synthetic material without any external mechanical action.

14. The method in accordance with claim 12 , wherein the identations are flattened in the laminating film through a mechanical action from the A-side.

15. The method in accordance with claim 1 , wherein an extended surface of a panel is provided by means of an embossing roll and an area of a panel with a surface structure,
wherein a recess area is provided in the applying of adhesive.

16. The method in accordance with claim 1 , for manufacturing a motor vehicle interior panel part.

17. A method for producing a laminate mold part comprising a vehicle interior panel or a vehicle interior panel part, comprising conducting a preparatory process whereby an adhesive is bonded to a B-side of a laminate film and a support part surface area of a support part by the following steps:
a. introducing the adhesive into the B-side of the laminate film;
b. introducing indentations into the B-side of the laminate film; and
c. producing the laminate mold part.

18. The method according to claim 4 , wherein the hot melt is applied to duct forming structures, so that air from a film surface can be drawn along form ducts between duct formation surveys, generating a diamond pattern.

19. The method according to claim 1 , wherein the laminate film is guided around a pressure roller to contact an embossing roller and, in one rotation, the pressure roller is guided around to a slot die.

20. The method claimed in claim 1 , wherein the adhesive is introduced into laminate film macroscopic indentations level with the surface connected to the B-side of the laminate film or through a surface application above the indentations.
