Abstract

The present disclosure relates to a method for filling a joint with an adhesive and/or sealing material. The method can include: a) positioning a first part, such as an insert, and a second part, such as a frame, so that the first and second parts form the joint; b) introducing a movable spacer into the joint; c) positioning a nozzle element over the joint; d) displacing the nozzle element along the joint such that the nozzle element strikes against the spacer and moves the latter forwards; and e) discharging the adhesive and/or sealing material out of an exit nozzle of the nozzle element during step d).

First claim

1 . A method for filling a joint with an adhesive and/or sealant, comprising:
a) positioning a first part, and a second part, such that the first and second parts form the joint; b) inserting a movable spacer into the joint; c) positioning a nozzle element over the joint; d) displacing the nozzle element along the joint such that the nozzle element abuts against the spacer and moves the latter forward; and e) discharging adhesive and/or sealant out of an outlet nozzle of the nozzle element during step d).

2 . The method as claimed in claim 1 ,
wherein the spacer is removed from the joint when a joint end or a joint corner is reached.

3 . The method as claimed in claim 2 wherein the spacer has a run-on bevel such that said spacer is lifted out when it abuts against a joint end or a joint corner; and/or wherein a run-on bevel is provided at a joint end or at a joint corner such that the spacer is lifted out when it runs against the joint end or the joint corner.

4 . The method as claimed in claim 1 ,
wherein multiple movable spacers are inserted into the joint, wherein at least in part, the multiple movable spacers are moved forward simultaneously by the nozzle element.

5 . The method as claimed in claim 1 , wherein
the joint comprises multiple joint segments which have an angle with respect to one another, and at least one movable spacer is inserted into each joint segment.

6 . The method as claimed in claim 1 , wherein
the joint has a rectangular shape and has four joint segments, wherein in each case two mutually adjoining joint segments are oriented perpendicular to one another, wherein at least one spacer is mounted in each joint segment, and wherein, in each case two spacers, before a displacement thereof, are inserted into in each case one corner region of the joint.

7 . The method as claimed in claim 1 , wherein
the nozzle element maintains its orientation as it passes through a joint corner.

8 . The method as claimed in claim 1 , wherein
at a joint corner, at least one of the surface sections adjoining the joint corner at an inner side, of the first or second part is covered by a covering.

9 . The method as claimed in claim 1 , wherein
the adhesive and/or sealant, in the initial state, during dispensing from the outlet nozzle, has a viscosity such that relative forces arising between frame and insert are compensated by the adhesive and/or sealant, wherein the adhesive and/or sealant has a viscosity of greater than or equal to 10 3 mPa*s.

10 . The method as claimed in claim 1 , wherein the movable spacer has a run-on bevel for setting a width of a joint between a frame as the first part and an insert as the second part, for the filling of the joint with an adhesive and/or sealant.

11 . A system for filling a joint with a sealant and/or adhesive, comprising:
a movable nozzle element with an outlet opening; at least one movable spacer; and a run-on bevel for lifting the spacer.

12 . The system as claimed in claim 11 ,
wherein the spacer has the run-on bevel configured as a convex section.

13 . The system as claimed in claim 11 ,
comprising: an adhesive and/or sealant, wherein the adhesive and/or sealant has a viscosity of greater than or equal to 10 3 mPa*s.

14 . A spacer configured for filling a joint with an adhesive and/or sealant, wherein the spacer comprises:
a run-on bevel such that the spacer is configured to be lifted upward when it abuts against an edge.

15 . The spacer as claimed in claim 14 ,
wherein the spacer has a cuboidal main body and/or a convex rib which forms the run-on bevel and which is arranged on one of the cuboid surfaces.

16 . The method as claimed in claim 1 , wherein
the joint has a rectangular shape and has four joint segments, wherein in each case two mutually adjoining joint segments are oriented perpendicular to one another, wherein in each case two spacers are mounted in each joint segment, and wherein, in each case two spacers, before a displacement thereof, are inserted into in each case one corner region of the joint.

17 . The method as claimed in claim 1 , wherein
the adhesive and/or sealant, in the initial state, during dispensing from the outlet nozzle, has a viscosity such that relative forces arising between frame and insert are compensated by the adhesive and/or sealant, wherein the adhesive and/or sealant has a viscosity of greater than or equal to 10 4 mPa*s.

18 . The method as claimed in claim 1 , wherein
the adhesive and/or sealant, in the initial state, during dispensing from the outlet nozzle, has a viscosity such that relative forces arising between frame and insert are compensated by the adhesive and/or sealant, wherein the adhesive and/or sealant has a viscosity of greater than or equal to 10 5 mPa*s.

19 . The system as claimed in claim 11 ,
comprising: an adhesive and/or sealant, wherein the adhesive and/or sealant has a viscosity of greater than or equal to 10 4 mPa*s.

20 . The system as claimed in claim 11 ,
comprising: an adhesive and/or sealant, wherein the adhesive and/or sealant has a viscosity of greater than or equal to 10 5 mPa*s.
