  • the mixing device has for the supply of the respective components inlet openings, via which the components are added into the mixing chamber of a mixing device.
  • the components are stored in upstream receptacles, such as can-shaped containers or cartridges, the mixing device being part of a means for providing putties.

  • the mixing chamber is formed from a tube section of a flexible tube, on the outside of which press rollers engage, which compress the tube section and simultaneously drive around a longitudinal axis.
  • the components Due to the friction occurring and the adhesion of the components to the inner wall of the tube, the components are mixed together. After the mix has passed through the tube section, it arrives at a hose provided on the tube Outlet opening, where it emerges continuously from the hose.
  • the tube wall is made of an airtight plastic, so that the air surrounding the tube during the mixing process does not get into the mix and can be trapped in this in the form of pores or voids.
  • the mixing components are mixed together so that the mix cures reliably.
  • this is achieved by having two storage containers and by connecting these storage containers to the mixing chamber via separate feed channels.

  • the supply channel 32b in the region of its end portion 32'b for the hardener component B in the device plate 30 has a diameter of preferably 1.5 mm to 1.6 mm and that the mixing device 1 on the device plate 30 in Area whose outlet openings 31a, 32a for the two components A and B is arranged such that the outlet opening 32a for the hardener component B in the device plate 30 at the inlet opening 17b and inlet hole for the hardener component B of the mixing chamber 14 abuts and with this is congruent, wherein the distance of the outlet opening 32b to the inlet opening 17b of the mixing chamber 14 of the wall thickness of the mixing chamber wall 14a is preferably 1 mm.
  • the diameter of the feed channel 32b is sized larger than the diameter of the feed channel section 32b, as the Fig. 44 shows.
  • the distance between the outlet opening 32a for the hardener component B and the inlet opening 17b of the mixing chamber 14 corresponds to the thickness of the mixing chamber wall 14a, preferably 2 mm, the path length for the flow of the curing agent component B from the outlet opening 32a to to the inlet opening 17b or until it enters the mixing chamber 14 very briefly with the result that the infiltrating in the mixing chamber 14 hardener component B meets the simultaneously flowing binder component A.
  • the mixing teeth 23, 24 are then used to mix the two components A and B to form the ready-to-use filler SM, which is dispensed or deposited on a spatula S (FIG. Fig. 43 . 44 ).
  • the hardener component B Since the hardener component B has a lower viscosity compared to the viscosity of the binder component A, the hardener mass when pressed out of its cartridge-like container 91 and when passing through the supply channel 32b in the device plate 30 due to the fact that micro in the hardener - Air bubbles are compressed. Becomes the pressure on the hardener mass taken back, then there is an expansion of the hardener mass, with the result that a backflow of hardener mass takes place.
  • a check valve 110 is arranged in the supply channel 32b for the hardener component B, whose arrangement in the supply channel 32b and its configuration in the Fig. 45 . 46 . 47 and 48 is shown.
  • the check valve 110 is disposed in the supply passage section 32'b.
  • a check valve 110 from a spring-loaded ball and check valves otherwise designed differently.
  • the check valve 110 is set so that at a minimum pressure on the check valve by flowing back hardener mass, the check valve is closed, so that a reflux is prevented.
