Definitions

  • the invention relates to a laboratory device for coating flexible webs, in particular textiles, with a heatable housing and a coating device connected upstream of the housing.
  • Laboratory devices of this type are used to examine coated fabrics.
  • the fabrics are clamped in a frame that is previously moved out of an oven.
  • the coating material is placed on the textile surface and evenly distributed by a coating device, which is located on the housing wall of the furnace, when the frame is pushed into the furnace.
  • the oven temperature and residence time can be regulated. After the heating process, the frame is pulled out of the oven and either a new sheet to be coated is clamped into it or the already coated sheet is again provided with coating material and pushed into the oven.
  • the object of the invention is to develop a laboratory device which allows continuous operation, which enables multiple coating and the examination of coatings under conditions close to production.
  • the housing has both a development and a winding for the flexible web (s) on the outside.
  • the web to be coated is unwound from this unwinding, coated with coating material, passed through the housing and rewound on the rewinder.
  • Such an arrangement enables the flexible web to be coated several times without having to change the wrap, since the flexible web can be rolled up from the rewinder through the housing back onto the unwind. A new coating process can then be carried out.
  • Heating elements are arranged within the housing. The flexible webs to be treated are passed through the housing and are thereby subjected to heat treatment.
  • At least one deflection roller can be provided in the interior of the housing and the unwinding and winding can be arranged on one side of the housing. Such guidance of the flexible webs extends the dwell time of the coating Tracks within the housing. To further reduce the device dimensions, the unwinding and winding can be arranged one above the other.
  • the laboratory device can have a coating device between the unwinder and the housing and a cooling roller between the housing and the winder.
  • the flexible web is provided with a coating material on the coating device before the flexible web now provided with coating material is drawn into the heatable housing.
  • the hot and coated web emerging from the housing is cooled on a chill roll and rolled up on the rewinder.
  • At least one revolving chain can run through the housing between the unwinding and the winding and the chain can have clips for receiving the flexible web.
  • the clips attached to the chains engage the edges of the flexible web and on the one hand cause the flexible web to be pulled through the housing for winding up and on the other hand cause the flexible web not to contract in width.
  • a laminating device with an upstream unwinding roller and a separating device with a downstream winding roller can be arranged between the coating device and the housing.
  • a heating element can be arranged within the housing at least on the upper side and / or on the lower side of the flexible web (s).
  • These heating elements can be designed as nozzle boxes which are connected to an air supply duct.
  • This air supply duct can be connected to an air heating device.
  • Such an air heating device heats the air which is supplied to the nozzle boxes via the air supply duct.
  • the flexible web (s) emerging from the one laboratory device can be guided via an additional roller into a subsequent laboratory device.
  • An additional roller enables the flexible web (s) to be able to be guided via this additional roller into the coating device of the subsequent laboratory device after leaving the first laboratory device.
  • several laboratory devices can be connected in series, the track (s) z. B. coated several times and / or can be subjected to several heat treatments with subsequent cooling.
  • FIG. 1 shows a laboratory device 1 for coating flexible webs 2, consisting of a housing 3 and an unwinder 4 and a winder 5.
  • the unwinder 4 is arranged above the winder 5 on one side of the housing 3.
  • the flexible web 2 is unwound from the unwinder 4 and passed over a reversing roller 6 before it is fed into a coating device 7.
  • the coating device 7 consists of a coating cylinder 8, over which a doctor holder 9 with doctor blades 10 is arranged. At the coating device 7, the coating material is applied to the flexible web 2 and evenly distributed on the flexible web 2 by the doctor blade 10.
  • the coating device 7 is followed by a laminating device 11, which consists of an upper laminating roller 12 and a lower laminating roller 13.
  • a laminating device 11 which consists of an upper laminating roller 12 and a lower laminating roller 13.
  • the coated flexible web 2 After passing through the laminating device 11, the coated flexible web 2 enters the housing 3, where it is deflected in the direction of the winding 5 by a deflecting roller 14.
  • the flexible web 2 is cooled and deflected by a cooling roller 15 and fed to a separating device 16.
  • This separating device 16 consists of an upper separating roller 17 and a lower separating roller 18.
  • the winding 5 is connected to the separating device 16.
  • nozzle boxes 19 are arranged as heating elements both on the top and on the underside of the flexible web.
  • the nozzle boxes 19 are connected to an air warming device 21 via an air supply duct 20.
  • the heated air is supplied to the nozzle boxes 19 by the fan 22 via the air supply duct 20.
  • an adjusting device 24 is arranged between each nozzle box 19 and the air supply duct 20 and is operated from outside the housing 3.
  • the ratio of fresh air supplied to the recirculated air is set via fresh air flaps 25 and a recirculated air flap 26. For example, only fresh air is heated in the open position of the fresh air flaps 25 and closed position of the recirculated air flap 26, while in the opposite case only recirculated air is heated up again.
  • the exhaust air leaves the housing 3 via an exhaust air flap 27.
  • the laboratory device is controlled via an operating panel 28, which is arranged on the outside of the housing 3.
  • the laboratory device 1 is suitable for both direct and indirect coating.
  • the flexible web 2 is unwound from the unwinder 4 and rolled up on the winder 5.
  • Chains 29 are guided around the deflection roller 14, a closer chain wheel 30 and an opener chain wheel 31.
  • the closer chain wheel 30 is located in the running direction of the flexible web 2 between the laminating device 11 and the entry of the flexible web 2 into the housing 3.
  • the opener chain wheel 31 is arranged between the exit of the flexible web 2 from the housing 3 and the cooling roller 15.
  • the chains 29 have brackets which through the closer chain wheel 30 in the edge of the flexible web 2 can be hooked. Only when the housing 3 of the flexible web 2 leaves the clips of the chains 29 on the opener sprocket 31.
  • a chain tensioner 32 is arranged on the outside of the housing 3.
  • a flexible web 2 is rolled up on the unwind 4, which has a high strength.
  • a paper web can be used as the flexible web 2.
  • the paper web 2 assumes the function of the chains 29, so that the chains 29 are not used.
  • the coating material is applied to this paper web 2 in the coating device 7 and distributed by the doctor blade 10.
  • the laminating device 11 follows.
  • a further flexible web 2 which is unwound from an unwinding roller 33 and deflected by a roller 34, is placed on the paper web 2 already provided with coating material.
  • Both flexible webs 2 pass through the housing 3 and are deflected by the deflecting roller 14.
  • the flexible webs 2 After exiting the housing 3, the flexible webs 2 are cooled on the cooling roller 15 and separated in the subsequent separating device 16.
  • the flexible web 2 designed as a paper web is rolled up on a winding roller 35 and the further coated flexible web 2 on the winding 5.
  • FIG. 2 shows the arrangement of two laboratory devices 1, 1 'connected in series for indirect coating.
  • the flexible webs 2 emerge from the housing 3 after the unwinding 4 and the heat treatment off, are cooled on the cooling roller 15 and pass through the separating device 16.
  • the flexible webs 2 are deflected only around the winding 5 in the direction of the laboratory device 1 'and pass through the additional roller 36 of the laboratory device 1' to the coating device 7. Then pass through the flexible webs 2 the laboratory device 1 'according to the embodiment of FIG. 1 for indirect coating.
