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

The invention claimed is:

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 spacer; and
e) discharging adhesive and/or sealant out of an outlet nozzle of the nozzle element during step d), wherein:
the spacer is removed from the joint when a joint end or a joint corner is reached, and
the spacer has a run-on bevel such that said spacer is lifted out when the spacer is further moved after the spacer initially abuts against the joint end or the joint corner; and/or a run-on bevel is provided at the joint end or at the joint corner such that the spacer is lifted out when the spacer is further moved after the spacer initially runs against the joint end or the joint corner.

2. The method as claimed in claim 1 ,
wherein multiple movable spacers are inserted into the joint, and
wherein at least some of the multiple movable spacers are moved simultaneously by the nozzle element.

3. 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.

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

5. The method as claimed in claim 1 ,
wherein an orientation of the nozzle element is maintained as the nozzle element passes through the joint corner.

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

7. The method as claimed in claim 1 ,
wherein the adhesive and/or sealant, in an initial state, during dispensing from the outlet nozzle, has a viscosity such that relative forces arising between the first part and the second part 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.

8. The method as claimed in claim 1 ,
wherein the movable spacer has a run-on bevel for setting a width of the 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.

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

10. The method as claimed in claim 1 ,
wherein the adhesive and/or sealant, in an initial state, during dispensing from the outlet nozzle, has a viscosity such that relative forces arising between the first part and the second part 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.

11. The method as claimed in claim 1 ,
wherein the adhesive and/or sealant, in an initial state, during dispensing from the outlet nozzle, has a viscosity such that relative forces arising between the first part and the second part 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.
