Claim Text:
1. A method of manufacturing glue-coated elements which are ultimately to be glued together to form a panel, comprising the steps of: providing a plurality of panel elements comprising at least a first panel element and a second panel element, each panel element having a profiled edge for engaging with another panel element, wherein the plurality of panel elements define the panel when engaged with each other; wherein the profiled edge comprises a tongue on the first panel element and a groove on the second panel element, wherein the tongue and the groove engage each other when the first and second panel elements are engaged with each other; and a mechanical draw-out resistance element on at least one of the tongue and the groove, wherein the tongue and the groove have substantially parallel surfaces, and wherein the draw-out resistance element comprises a separate element extending from one of the tongue and the groove toward the other of the tongue and the groove and angled in a direction of insertion of the other of the tongue and the groove relative to the one; applying a one-component adhesive to at least a portion of the profiled edge; and before the elements are joined together, reducing moisture content of the adhesive on the elements to a point of moisture content equilibrium to form a dried adhesive film on the profiled edges such that, when the elements are joined, dried adhesive films on the profiled edges of the elements bond together and wherein the mechanical draw-out resistance element comprises positively engaging sections defined on the tongue and the groove, wherein the positively engaging sections have a height less than the thickness of the film.
