- a drive shaft 37 leads from the universal joint 36 against a fixed wheel drive (not shown).
- the press wheel and / or the fixed wheel drive is preferably designed as a hydraulic motor.
- these can preferably be driven in series by a common pump and the drive speed is set via a flow controller. So that the hydraulic motors operated at the fixed and press wheels 3 and 4 lead to essentially the same circumferential speeds, the motor volumes are preferably adapted to the different circumferential lengths of the two wheels 3, 4.
- FIG. 4 schematically shows a pipe bend 38 with three segments 38a, which are connected to one another via fold connections 39. To close the fold connection, the interaction of the fixed wheel 3 located in the pipe bend 38 with the press wheel 4 and the closing disk 5 is required.
- FIG. 5 shows how, around a single rim 40 of the upper tube segment 38a, the upstanding edge of a double rim 41 of the lower tube segment 38a can be folded over by the closing disk 5 by its swiveling feed and pressed against the pressing wheel 4.
- the guide device between the first and the second bearing part 14, 28 is not restricted to an arrangement in which guide grooves 17 are formed on the second bearing part 28 or the guide blocks 16 connected thereto. Rather, embodiments are also possible in which bearing rollers are provided on the second bearing part and guide grooves are provided on the first bearing part. Instead of the combination of grooves and rollers, a combination of webs and rollers running on both sides of the webs would also be conceivable. The mirror-symmetrical arrangement of pairs of grooves and rollers is also not absolutely necessary, since one-sided guides could also be made sufficiently stable. In addition, the first bearing part 14 could also be guided on the machine stand. In principle, any guide known to the person skilled in the art that can pivot the closing roller can be used.
