<p>A jointing machine for the folding of seams in manufacturing of seamed metal sheets made of segments of metal sheets is disclosed, wherein the machine includes a locking wheel pivotably positioned in a recess of a resiliently disposed locking wheel carriage. The seam during formation is supported from below by a support roller, and is held from the sides by an adjustment roller together with the locking wheel. The locking wheel carriage is positioned diagonally relative to the surface of the support roller, which enables the machine to manufacture folded seams in very small metal sheet segments, and to utilize thick or hard metal sheets. The particular arrangement of the jointing machine of the present invention which respect to the locking wheel carriage diagonal positioning enables the locking wheel to penetrate even restricted spaces, and the folding of the seam can be accomplished in several steps wherein the use of the locking wheel carriage ensures the transmission to the seam of sufficient force to form a strong folded joint.</p> |
