  • the first Counter roller 10, which cooperates with the first pressure roller 8, is mounted on a further carriage 12 which is movably held on the base body 2, wherein the two carriages 5,12 include a right angle.
  • the second counter-roller 11 is rotatably mounted directly at the end of a leg of the base body 2. Furthermore, a force-receiving roller 13 is provided on the base body 2.
  • a second roller-folding head which corresponds to the roller-folding head shown in FIG.
  • the second Rollfalzkopf carries a third and a fourth pressure roller 20,21 and a third and fourth counter-roller 22,23, although the fourth counter-roller 23 is held immovably on the base body 2.
  • the further carriage 12 is replaced by a wedge-shaped holder.
  • a Rollfalzkopf can be used according to Figure 2.
  • FIGS 3a to 3d show the connection of a roof 30 with the frame 31 of a sliding roof.
  • an opening is recessed, wherein the opening edge is placed to a flange 32 which extends approximately perpendicular to the surface of the roof 30.
  • the frame 31 terminates in a web 33 which is parallel to the flange 32.
  • the flange 32 is higher than the web 33, whereby a connection between the roof 30 and frame 31 can be made by the protruding part of the flange 32 is bent by 180 ° around the web 33 around. This is done in four folding operations, which are shown in the figures 3a to 3d gradually.
  • the protruding part of the flange 32 is bent by about 45 °.
  • a pair of roles is provided.
  • the first pressure roller 8 interacts with the first counter roller 10.
  • the first pressure roller 8 has a conically widening folding section 34, the conicity of which corresponds to the intended bending of the flange 32.
  • a cylindrical portion of the first pressure roller 8 abuts against the flange 32.
  • the first counter roller 10 runs along the web 33 on the inside. Thus, no forces are introduced into the frame 31 or into the roof 30.
  • the second pressure roller 9 cooperates with a second counter roller 11.
  • the second pressure roller 9 is a cylinder without a conical section.
  • the slightly inclined second counter roller 11, also called folding roller, pushes the flange 32 by a further 45 °.
  • a fourth pressure roller 21 or a fourth counter roller 23 is used;
  • the fourth pair of rollers is either formed according to Figure 1 at a second Rollfalzkopf or is generated by rotation of the turret 24 according to Figure 2, wherein the fourth pressure roller 21 is again represented by the second pressure roller 9.
  • the individual positions are achieved by always the entire Rollfalzkopf 1 is rotated and the carrier 4 is guided by means of the carriage 5 in the respective folding position.
  • the invention therefore also relates to a method for folding the flange about the other, parallel thereto flange in at least two successive Steps, wherein at least in the first step, the mutually parallel flanges 32, 33 by moving a movable carriage 5 and arranged on the carriage 5 pressure roller 8, 9 or 20, 21 of the pressure roller 8, 9 or 20, 21 and a counter-roller against each other are pressed and the flange 32 is partially flanged, wherein in at least one subsequent step, the flange 32 is further crimped by a correspondingly aligned counter-roll.
  • a tapered portion of the pressure roller takes care of the partial edging of the first step.
  • the pressure roller essentially has the task to guide the Rollfalzkopf the flange, it may be a single cylindrical body which rests against the unrebated portion of the flange and rolls it. Each provided with a conical section counter rollers are aligned in each case according to the desired progress in the flanging to the flange.
