Sliding dovetail joint element e.g. profile board or profile strip, has ridge collar formed as hollow-cylindrical ridge groove, which includes ridge groove leg for partially limiting ridge groove and ends at recess of ridge collar

摘要

The element (1) has a cylindrical ridge part (3) provided in a longitudinal edge of the element and with a ridge collar that is formed in deep-round shape. The ridge collar is formed as a hollow-cylindrical ridge groove (2) in another longitudinal edge of the element. The ridge groove includes a ridge groove leg (4) for partially limiting the ridge groove, and includes ends at a recess of the ridge collar, where the element is formed with a closed circular cross-section and an arbitrarily curved-shape mold and made of an inorganic material or plastic material.
