Abstract: The invention relates to a method for machining a locking groove (9) into a groove flank (5, 6) of a panel comprising an upper and a lower side, whereby the locking groove is provided in the part of the joint groove (4) surrounded by the groove flanks, whereby the locking groove is machined by means of a rotating milling tool (12), comprising a drive (14), a milling head (13), a transmission device (11) for the rotational movement and a mounting for the milling head. The milling has a free radius (r) at least on the mounting side due to the mounting and, during the machining of the locking groove, the milling head (13) has at least a significant proportion of the free radius (r) thereof, in particular, the entirety thereof located in the part of the joint groove surrounded by groove flanks.

Abstract: The invention relates to a panel having means for the detachable connection of adjacent panels by means of pivoting, the means provided comprising, on a first edge, a projecting tongue (3) with a lower and upper tongue surface (4, 5) which divides the edge into an upper and a lower edge section (7, 6), the second edge situated opposite the first edge having a groove (8) which corresponds to the tongue of an adjacent panel and which is enclosed by an upper-side and a lower-side panel section, the upper tongue surface having a projection (13) with a contact surface (14) which is directed rearwardly in the direction S of the upper edge section, and the upper-side panel section having on its lower side a recess which at least partially accommodates the projection and which has a complementary surface (16) interacting with the contact surface, the complementary surface interacting with the contact surface of an adjacent panel in the pivoted-in state.

Abstract: The invention relates to a panel, with a tongue on a longitudinal and a transverse edge, projecting beyond said longitudinal or transverse edge, with essentially parallel tongue surfaces and a groove on the opposing longitudinal or transverse edge, enclosed by lateral panel sections, corresponding to the tongue of an adjacent panel with essentially parallel groove edges. In order to lock two adjacent panels such as to run into each other, a projecting locking element is provided on at least one tongue surface at least in parts and in each region of (a) panel section(s) corresponding to said locking element(s) for connected panels a recess(es) is provided, whereby the region (B) of the tongue with the locking element and/or at least one of the regions of the tongue and the panel sections which are in contact on introducing the tongue into the groove, before the locking element clips into the recess, have an elastic embodiment such that said elasticity is greater than the elasticity of the locking element.
