Method for manufacturing leaf elements of building closures which are cuttable and versatile with adjoining wooden strips by tonguing and grooving with a central bearing surface

摘要

The invention relates to the manufacture of building closure elements (leaves) made up of adjoining wooden strips 2 by tonguing and grooving with a central bearing surface 3 with largely clear joints 4 hiding the dimensional variations in the strips and providing perfect removal of trickling water. These strips 2, joined together by bars, wooden keys or wooden pegs, form elements (leaves) which can be cut heightwise and widthwise making it possible to make up building closure assemblies with one or more leaves to the user's dimensions. The method of tonguing and grooving with the central bearing surface 3 and its variants according to the invention is particularly intended for the manufacture of building closures using cuttable and versatile elements according to the invention, but also for the manufacture of made-to-measure assemblies.
