Mechanical locking of floor panels with a glued tongue

摘要

A tongue with edge sections that are used to glue the tongue into a groove of panel. A tongue for connection of a building panel, said tongue is of an elongated shape and made of molded plastic, the tongue including at least two protrusions at a first long edge of the tongue, wherein the protrusions are bendable in a plane parallel to the upper surface of the tongue and extending essentially in the parallel plane and, wherein the tongue has a second long edge, which is essentially straight over substantially the whole length of the tongue and the tongue includes a gluing part configured to be glued into a groove at an edge of the building panel.

1. A tongue for connection of a building panel, said tongue is of an elongated shape and made of moulded plastic, the tongue comprising at least two protrusions located at different positions along a first long edge of the tongue,
wherein the protrusions are bendable in a plane parallel to the upper surface of the tongue and extend essentially in the parallel plane, wherein the tongue has a second long edge, which is essentially straight over substantially the whole length of the tongue, the tongue further comprising a gluing part configured to be glued into a groove at an edge of the building panel, wherein the gluing part comprises a gluing strip extending in the longitudinal direction of the tongue, and wherein the gluing strip is attached to outer ends of at least some of the protrusions so that there is a gap between the gluing strip and each of the protrusions in a direction extending from the first long edge to the second long edge.
