Method for the production of profiled floor elements from a timber material

Abstract

A method is described for the production of profiled floor elements from a timber material, comprising at least one covering flange protruding from a footing and having a rounded longitudinal edge, with the method proceeding on the basis of a pre-profiled floor element consisting of profiled floor elements connected along a longitudinal edge by means of a connecting land and the profiled floor elements being separated from each other by machining the connecting land on the profiled side opposing the visible side once a covering layer has been adhesively bonded to the pre-profiled floor element in the region of the visible sides of the subsequent profiled floor elements. In order to ensure advantageous production conditions, it is proposed that the strips of the covering layer corresponding to the individual profiled floor elements are adhesively bonded to the pre-profiled floor element, which forms a connecting land bridging the wedge-shaped recess between the rounded longitudinal edges on the side of the covering flange facing away from the visible side, and that the edge sections of the strips, which face each other and protrude into the wedge-shaped recess, are bent into the wedge-shaped recess between the rounded longitudinal edges of the covering flange and are adhesively bonded to the longitudinal edges before the connecting land is machined away on the underside of the covering flange.

Description

1. FIELD OF THE INVENTION[0001]The invention relates to a method for the production of profiled floor elements from a timber material. Said elements are provided with at least one covering flange that has a rounded longitudinal edge and projects from a footing. Said method commences with a pre-profiled element consisting of profiled floor elements connected to each other along a longitudinal edge by means of a connecting land. The profiled floor elements are separated from each other after a covering layer is adhesively bonded to the pre-profiled element in the area of the visible sides of the subsequent profiled floor elements by machining the connecting land on the side of the profiled element facing away from the visible side.2. DESCRIPTION OF THE PRIOR ART[0002]In order to reduce the production effort for the manufacture of profiled covering strips coated on the visible side, a method is known (EP 0 862 976 A1) which proceeds on the basis of a pre-profiled element that correspon...

Benefits of technology

[0003]Consequently, the object of the invention is to create a method for producing at least two profiled floor elements of the kind described at the outset such that a covering layer can be adhesively bonded to the pre-profiled element in a simple manner despite the wedge-shaped recess produced between the abutting longitudinal edges of the subsequent profiled floor elements such that the visible side of the profiled floor elements obtained from the coated pre-profiled element are completely coated.

[0006]For this purpose, provision can be made for the connecting land of the pre-profiled element to connect the spatially separated longitudinal edges of the covering flange and for the covering layer extending across and beyond the wedge-shaped recess between the rounded longitudinal edges of the covering flange to be adhesively bonded to the pre-profiled element before the covering layer is severed in the wedge-shaped recess to form strips and is pressed against and adhesively bonded to the rounded longitudinal edges in a stripwise manner. Adhesively bonding a covering layer which is common to the profiled floor elements to be created onto the pre-profiled element in a bridging manner provides simpler conditions for attaching the covering layer. However, provision must be made for a gap between the sides of the abutting longitudinal edges by widening the connecting land accordingly to ensure a sufficiently wide edge area between these longitudinal edges for the individual strips produced so that each of the individual longitudinal edge curvatures is covered after the covering layer has been severed in the area of the wedge-shaped recess. However, widening the connecting land increases the volume to be machined away.

[0008]Provision for a pre-profiled element from which two or more profiled floor elements can be obtained results in advantageous conditions for automated production in series because, among other things, the pre-profiled element has a greater inherent strength than individual profiled elements and can also be conveyed better, especially if the pre-profiled element is provided with at least one guide groove in the area of the connecting land between the profiled floor elements because in this case the pre-profiled element can be conveyed along the guide groove immediately before the connecting land is machined away, something which not only improves production precision, but also allows an increase in the processing speed.
