Abstract

A method and device for inserting a tongue in an insertion groove in a panel. The method includes displacing a first tongue to an end position of a tongue queue, which comprises tongues under compression, in a tongue queue device, compressing the first tongue, displacing the tongues in the tongue queue by compression forces from the tongues under compression, displacing a second tongue, which is at a front position of the tongue queue, to an inserting device, displacing the second tongue into an insertion groove in a panel by said inserting device.

First claim

The invention claimed is:

1. A method for inserting a first tongue of a tongue queue including a plurality of tongues, in an insertion groove in a panel, wherein the method comprises:
displacing a second tongue to an end position of the tongue queue, which comprises the plurality of tongues under compression, in a tongue queue device,
compressing the second tongue while in the tongue queue device,
displacing the plurality of tongues at least partly by compression forces from the plurality of tongues under compression in a direction of a tongue queue path,
displacing the first tongue, which is at a front position of the tongue queue, to an inserting device,
displacing the first tongue into an insertion groove in the panel by said inserting device.

2. The method as claimed in claim 1 , comprising separating the second tongue from a tongue blank by a separating device.

3. The method as claimed in claim 2 , comprising performing said compressing by the separating device.

4. The method as claimed in claim 3 , comprising performing said separating and compressing by rotating a tool.

5. The method as claimed in claim 1 , comprising displacing the second tongue from the end position to the front position.

6. The method as claimed in claim 5 , comprising rotating the second tongue during said displacing of the second tongue from the end position to the front position.

7. The method as claimed in claim 5 , comprising displacing the second tongue in a first direction and in a second direction, which is perpendicular to the first direction, during said displacing of the second tongue from the end position to the front position.
