Abstract

A device for producing an edging of a flat extended panel has: a molding tool; a material dispenser which is movable in relation to the molding tool, for dispensing a material for the edging, wherein the molding tool has: a first mold body having a holding region for the panel; a second mold body having a holding region for the panel such that the panel is capable of being held by the first mold body and by the second mold body; a third mold body which with the first mold body shares a common contact region, wherein the first mold body, the second mold body, and the third mold body are configured such that they conjointly with the panel surround a space in which the edging is configurable; an access duct to the space, the former being configured between the second mold body and the third mold body.

Claims

1. A device for producing an edging of a flat extended panel, the device having:

a molding tool;

a material dispenser which is movable in relation to the molding tool, for dispensing a material for the edging, wherein the molding tool has;

a first mold body having a holding region for the panel;

a second mold body having a holding region for the panel such that the panel is capable of being held by the first mold body and by the second mold body;

a third mold body which with the first mold body shares a common contact region, wherein the first mold body, the second mold body, and the third mold body are configured such that they conjointly with the panel surround a space in which the edging is configurable; and

an access duct to the space, the former being configured between the second mold body and the third mold body;

wherein an elastic lip seal is fixed to the second mold body and/or to the third mold body, so as to close and temporarily unblock the access duct.

2. The device according to claim 1, wherein the second mold body and the third mold body are disposed so as to be movable in relation to one another.

3. The device according to claim 1, further comprising a separate closure element which is introducible into the access duct, so as to close the access duct in order for the space to be a closed space.

4. A method for producing an edging of a flat extended panel, the method comprising:

providing the panel;

providing a first mold body;

laying the panel onto the first mold body;

disposing a second mold body on the panel;

disposing a third mold body such that the third mold body contacts the first mold body, wherein a space between the first mold body, the second mold body, and the third mold body, having an access duct between the second mold body and the third mold body, is configured; and

introducing a material for the edging through the access duct into the space;

the method further comprising;

moving an elastic lip seal which is fixed to the second mold body and/or to the third mold body, on account thereof unblocking the access duct;

introducing the material through the unblocked access duct; and

closing the access duct.

5. The method according to claim 4, the method further comprising:

installing a separate closure element in the access duct after the material has been introduced into the space, so as to close the access duct, on account thereof closing the space.

6. The method according to claim 5, the method further comprising:

installing a flexible sealing tape in the access duct.
