Abstract
A method for applying a seal onto a plate, including, providing a tool containing at least one support element made of solid material including a recess, a support element made of flexible material including a first part and a second part where said support element made of flexible material is arranged at least partially in said recess, and a means for exerting a pressure in a compensation chamber of said recess, where said compensation chamber is delimited at least partially by said second part of said support element made of flexible material.
Claims12
1:
- A method for applying a seal onto a plate, comprising:
- providing a tool, comprising:
- at least one support element made of solid material comprising a recess,
- a support element made of flexible material comprising a first part and a second part wherein said support element made of flexible material is arranged at least partially in said recess, and
- a means for exerting pressure in a compensation chamber of said recess, wherein said compensation chamber is delimited at least partially by said second part of said support element made of flexible material;
- delimiting an edge of interest on a portion of the plate on which the seal is to be applied,
- placing the plate on the tool such that the edge of interest rests at least on said support element made of flexible material,
- holding the plate on the tool in a predetermined reference position,
- applying said seal on the edge of interest, and
- removing the plate and the seal thereof applied from the tool,
- wherein the first part of the support element made of flexible material is a fixed part and the second part is a mobile part of the support element made of flexible material, and
- wherein the edge of interest of the plate rests at least on said mobile part of said support element made of flexible material and that the support element made of flexible material is made in one piece and encompasses the edge of interest of the plate along a contour of the plate.

2:
- The method according to claim 1, wherein a spacer is provided in the recess between the fixed part of the support element made of flexible material and means to maintain in place the fixed part of the support element made of flexible material.
3:
- The method according to claim 1, wherein said support element made of flexible material is made of an elastic material having a Shore A hardness of less than 90.
4:
- The method according to claim 1, wherein the means for exerting pressure is a means wherein air is injected.
5:
- The method according to claim 2, wherein said spacer is part of the support element made of solid material.
6:
- The method according to claim 1, wherein said plate is a glass plate.
7:
- The method according to claim 1, wherein said plate is an automotive glazing selected from a roof n a windshield.
8:
- The method according to claim 1, wherein said support element made of flexible material is configured to fit with edges of the plate along a periphery of the plate.
9:
- The method according to claim 1, wherein the seal is a reactive mixture containing polyurethane, formulated to produce an elastomer material containing polyurethane and having a density greater than 400 kg/m3, applied as a hardenable composition.
10:
- The method according to claim 1, wherein an elastic material having a Shore A hardness of less than 90 is used on at least a surface of the support element made of flexible material,
- and wherein the plate rests on the elastic material.
11:
- The method according to claim 1, wherein the seal is flush with the edge of interest on a portion of the plate on which the seal is to be applied.
12:
- A tool for performing a method for applying a seal onto a plate, comprising:
- at least one support element made of solid material comprising a recess,
- a support element made of flexible material comprising a first part and a second part wherein said support element made of flexible material is arranged at least partially in said recess, and
- a means for exerting pressure in a compensation chamber of said recess, wherein said compensation chamber is delimited at least partially by said second part of said support element made of flexible material;
- wherein the first part of the support element made of flexible material is a fixed part and the second part is a mobile part of the support element made of flexible material and
- wherein an edge of interest of the plate rests at least on said mobile part of said support element made of flexible material.
