The two flat strips 5 and 6 made of metal are increasingly formed from flat bodies into a tubular body, which possesses a right-angled cross-section. The strips are entered at one end of the machine and exited in the form of a continuous, right-angled pipe body or channel at the other end of the machine. The body manufactured in this way can ^ Assume any predetermined position if the roll storing the strips 5 and 6 is dimensioned accordingly.

The mechanism used for the introduction and the beginning of the folding ; mus C (Fig. 3) is controlled by a handle 93, which on a rotatably mounted, transversely extending shaft 94 is fixed. A control body 95 is located at each end of the shaft 94 13 of the drawings. The control body 95 are attached to the shaft 94 and have an irregularly shaped Control surface, which is used to control the relative movement of the * rollers 17 and 28 in the direction of the rotatable rollers 18 and 29 and is provided in this direction. this happens by means of rollers or control runners 96 which are arranged at each end of the rollers 17 and 28.

An electrical switch is also closed, which activates the drive motor of the machine and rotates the rollers 17, 18, 28 and 29 around the strips 5 and 6 to be carried out by the machine.

If a flat seam is desired, the frame F can be constructed long enough to accommodate the in FIGS. 3o-32 shown Bear Mechanism. The description of this structure follows after the explanation of the FIGS. 17-29 shown - leadership.

An exception is that the die body and rollers are so constructed and arranged that they form the seams of f the corners of the rectangular tube. The same racks can be used if desired. As shown, strips of various widths are used in this embodiment. The same embodiment of initiating and initial folding mechanism can be used, the only exception being that the rolls are of different construction. In Fig. 17 of the drawings, the station No, 1 is shown, in which the vertically movable roller Ho is made considerably shorter, by one
