  • the operating arms are also with each one of these bolts in the curve of the cam.
  • the actuating arms, guide disks and cam disks are preferably on both sides of the Drum arranged. This results in a more even distribution of the force.
  • the cam disc can be designed to be motor-adjustable in relation to the guide disc his.
  • the adjustment of the distance between the boundary surfaces of the dwelling compartment can be set in a particularly simple way.
  • a treatment medium is applied to the web and then by a dwelling compartment formed between two spaced-apart boundary surfaces guided. For setting the dwell time of the goods in the dwelling compartment this distance is set depending on the goods to be treated.
  • a drum having a surface with a variable radius provided at the surface as described above is trained.
  • drums can also be used in a different context can be used advantageously with an indwelling compartment. Areas of application arise everywhere wherever drums with surfaces with variable radius are to be used.
