  • the dividing walls 43 and 44 may be formed in various manners, for example, by welds of the parts extending over two parts of the mangle roll 12, the partitions 43, 44 arise by welding seams for connecting these parts to their parallel to the longitudinal central axis 14 of the ironer roller 12 extending transverse edges.
  • the cavity 39 extends from the gap 23 between the deflection drums 20, so the beginning of the inlet region 21.

  • a discharge line 53 leads to a further steam trap 54 and from there through a discharge line 56 to an outflow.
  • condensate expansion device 52 In the condensate expansion device 52, re-evaporation of the cooled fresh steam originating from the first cavity 39 takes place. This creates relaxation steam, which is also referred to in the jargon as Brüdendampf.

It is therefore sufficient if steam with less energy, in particular a lower energy density, is used for heating the flattening surface in the cavity 40 associated with the rear portion of the flattening surface.

It is also conceivable to form braided bands of two or more than two consecutive and preferably the same mangle rolls 12. These can be 10 driven circumferentially as in the ligament deficiency, preferably resting at variable speed or 38 according to the ligament deficiency. The heating of the individual successive mangle rolls 12 of such ribbon mangles can be carried out as well as the ribbon mangles 10 and 38.
