  • 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 mixture has passed through the tube section, it arrives at an outlet opening provided on the tube, where it emerges continuously from the tube.
  • 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 Lunkem.

  • the invention is based on the fact that the filling heights of the hardener component B and the binder component A are different in their reservoir, resulting in that mixing ratios between the two components are obtained at the beginning of the tapping, the one Contain greater amount of hardener components, so that a predetermined and required mixing ratio is not obtained.

In a 10 kg reservoir for the binder component A, a pressure of 0.15 bar is exerted on the binder component A. Of course, this is not enough to transport Binder Component A, as that would require 400kg of traction. This is not achievable.

  • the cold insulating layer 158 extends into the outlet channel 207 for the binder component A or into the mixing device 1 of the device 100 (FIG. Fig. 9 ).
  • the channel system 157 is provided with a feed channel 157 'and a drain channel 157.
  • the coolant is filled at 159.
  • the channel section 157a which interconnects the two channel sections 157b, 157c, is provided with a closable opening at 159 ,
  • cold air can be used in addition to water or other suitable cooling fluid.
  • the cooling device 155 is formed in a manner known per se. Thermoelectric coolers can also be used.
  • the support and base plate 104 'and the cold transport plate 104 "for the reservoir 90 is formed according to the support plate 104' and ensures a secure mounting of the reservoir 90 on the base plate 156, which is provided with corresponding through holes, so that the binder component A for the mixing operation of the mixing device 1 can be supplied.
  • suitable materials are used with the task that the filling head 104 is cooled altogether, because the task of cooling should be to cool the support and base plate 104 'for the reservoir 90 so that the container contents, especially in the bottom region of the Reservoir 90, compared to the warm ambient air is cooled down and that to the particular desired and predetermined temperature.
  • the temperature of the support and base plate 104 'or of the cold transport plate 104 "can be measured at predetermined time intervals and compared with a predetermined temperature value has the desired and required temperature.
  • Fig. 11 shows, the support and base plate 104 'for the reservoir 90 for the binder component A, a cold transport plate 104 ", which is provided with a channel system 157 with a number of channels for the cooling liquid, z. As cooling water is provided, which are formed in the plate material.
  • This cooling transport plate 104 is cooled by the coolant flowing through the channels, so that the reservoir 90 is cooled in its bottom region and preferably in the region of its outlet opening 90 'and the binder component A located in this region or to the predetermined temperature If the temperature of the binder component A should be above the predetermined and required temperature, the channel system 157 has a supply channel 157 'and a discharge channel 157 "running parallel thereto, which extend over the Whole of the size of the bottom of the reservoir 90 predetermined area of the support and base plate 104 'and the refrigerant transport plate 104 "extend and are arranged so that the two channels 157', 157" formed on both sides of the bottom of the reservoir 90 Outlet opening 90 'for the binder component A lost.
  • the storage container 90 is then placed on this cold transport plate 104 ", in which the channel system 157 is designed such that the entire plate and in particular the region which lies in the region of the outlet opening 90 'in the bottom plate of the storage container 90 is cooled "is then provided with a through hole which is congruent with the inlet opening in the support and base plate 104 'which communicates with an outlet channel 160 which leads to the outlet opening 161 for the binder component A in the mixing device 1 ( Fig. 11 ).
  • Another way of cooling the binder component A after Fig. 11 consists in that the carrying and standing plate 104 'or the cold transport plate 104 ", on which, for example, the reservoir 90 formed as a tin can for the binder component A, is cooled with chilled water 165 cooled, which is in a refrigerator 166.
  • the water tank 165 is connected to the two channels 157 ', 157" of the cold transport plate 104 ".
  • a pump 167 for supplying the cooled water to the cold transfer plate 104 "
  • the cold transfer plate 104" is provided with a downwardly directed metal tube 168.
  • the cold transport plate 104 " is insulated from the filling head 104 of the device 100 so that no cold can be transferred from the cooled cold transport plate 104" to the filling head 104.
  • the mixing nozzle made of plastic of the mixing device 1 in the refrigerator 166 is stored. If such a pre-cooled mixing nozzle is used, the part of the binder component A entering the mixing nozzle is also cooled down, so that a uniformly cooled and mixed putty material emerges, whereby the processing of the putty mass is positively influenced.
