Definitions

  • a contactless bending of a dense strip material can e.g. by using a known hollow cylinder with perforation in the required arch section and through Compressed air flowing out of the perforation openings be achieved. Between the belt and the cylinder is an overpressure gap is formed which prevents contact changes.
  • dense tapes and foils of greater thickness and Rigidity can work this method satisfactorily ten.
  • the stiffness and density of a textile tape is depending but so insignificant that this procedure is locally famous tion cannot be avoided.
  • the device according to the invention works so that pressure air 7 from the row-shaped openings 9, 9 'in the through the pillars 7 and 7 'indicated directions flows out and in accordance with the laws of wall flow of curvature the arched wall 2 follows.
