<p>For joining the edges (33, 37) of two flat elements (31, 35) which lie approximately in parallel along a common section, the common edge has at least one grabbing element (39) whose shape in the direction of edges accurately meshes with the cutout (43) on the edge (37). At least one protrusion (47, 49) on the edge (33), which is with respect to the grabbing element disaligned on both sides in the direction of meshing, leans in the direction of edges accurately against the element (35) with a cutout. In an analogue way, for joining the contacting edges (33, 37) of the open ends of a ring-shaped belt, a grabbing tongue (39) is positioned preferably in the centre of the edge (33) with two clips (40, 41) protruding on both sides of the tongue. The tongue accurately meshes with the cutout (43) with an approximately the same overlapping surface and is placed approximately in the middle of the other edge (37). On the edge (33) on each side of the tongue (39) is positioned a protrusion (47, 49), preferably on each end of the edge. In the direction of the edge towards the cutout each of these protrusions mesh accurately with the shape of the belt element (35) with the cutout (43).</p> |
