Definitions

  • the invention relates to a device for the continuous production of multi-layer flat materials or other workpieces in which the Layer materials between two endless press belts forming a reaction zone led, heated or cooled there and by at least one press belt on the Layer materials a pressure is exerted, this press belt in the reaction zone on the side facing away from the workpiece at least one with a gaseous one or pressurized liquid medium on the side facing away from the press belt Side with a pressure plate cooperating pressure chamber is assigned.
  • the one sealed by the sealing strip against the rotating press belt Gap can occur in the event of malfunctions due to uneven wear of the sealing strips, a clamping of the frame in the groove of the pressure plate, a change the width of the workpiece or the like. lead to loss of print media, causing Surface defects in the product can occur.
  • a continuously operating plate press is also known (DE-A-22 22 419), at the one opened to the working strand of the endless press belts and through the working strand limited, pressurized pressure chambers in sliding press parts are arranged.
  • the endless press belts must be used associated pressure chambers are provided with circumferential seals, the width of the pressure chamber being matched to the format width of the workpiece must become.
  • the invention has for its object a device of the aforementioned Art to design so that a limitation of the pressure space directly through the Press belt and thus a sealing gap between the rotating press belt and the lateral limitation of the printing space is eliminated and a format change for the Workpieces can be made without this adversely affecting the Tightness of the pressure pad could affect.
  • this slide film as a separate functional part between the pressure pad and the endless belt is arranged, this slide film is a wearing part represents exchangeable in a simple manner.
  • the due to the friction between the wear film and the endless rotating Strip heat can be used as process heat.
  • the reaction zone is on each side by a pressure plate 5 and a pressure iron 6 formed.
  • the pressure plate 5 is composed of an insulating plate 7 and a heating plate 8 together.
  • the pressure pad 6 is in the embodiment of FIGS. 1 to 4 and according to FIG. 6 formed by self-elastic hoses 10 which extend transversely to the press belts 1, arranged side by side and are pressurized on the inside.
  • This Pressure medium can be gaseous or liquid or hydropneumatic be.
  • the pressure pad 6 is shown in plan.
  • the interiors of the adjacent tubes 10 are on the long sides of the pressure pad connected to one another by distribution channels 11, so that the pressure medium into one of these distribution channels through metal parts can be formed, is introduced.
  • the print medium can be designed standing or be guided all round.
  • a sliding film 12 is arranged can consist of polytetrafluoroethylene and on the front, across Press band extending end 13 of the pressure plate 5 is fixed is.
  • the fixing can be done by screws 14 so that the sliding film can be replaced as a wearing part in a simple manner.
  • the other end of the slide film lies freely on the working side of the press belt 1 on.
  • Fig. 6 shows an embodiment in which the between Hoses 10 formed pressure pad and the press belt 1 arranged slide film 12 releasably attached to both ends 15, 16 of the pressure plate 17 is.
  • the slide film can also be used as an endless band running around the printing plate be executed.
  • FIG 3 shows a partial section of a double belt press in idle mode, in which the interior of the tubes 10 with a pressure medium filled, but the tubes 10 are not deformed, and thus limit the press nip.
  • Fig. 4 the part of the double belt press according to Fig. 3 is in production shown. Due to the thickness of the workpiece 3, the Reaction zone of the double belt press passes through, the self-elastic Hoses 10 deformed elliptically.
  • Any format of a workpiece can be passed through the reaction zone without leakage and leakage in the area of the pressure pads of pressure medium can occur in the atmosphere.
  • FIG. 5 While in the described embodiment, the pressure pad through Self-elastic extending transversely to the transport direction of the workpiece 3 Hoses is formed, is an embodiment in FIG. 5 shown, in which the pressure chamber 18 through an elastic membrane 19 is limited, the free edge 20 close to the pressure plate 5 is set.
  • the working pressure is generated by the pressure plate introduced pressure medium built up, which can be gaseous or liquid.
  • a slide film 21 is arranged between the membrane 19 and the press belt 1 of the belt press.
  • this slide film exclusively on the Face 13 of the pressure plate 5 releasably attached by means of screws 14.
  • the sliding film can also be designed as an outer layer of the membrane. You can also an inner coating of the interacting with the pressure chamber Form press belt.
  • the hoses 10 can also be provided with a sliding layer on the outside, so that the slide film 12 is omitted.
  • this consists of each press belt 1 assigned pressure pad 6 and the pressure plate 17 from several mutually independent units 22, so that the production operation can continue to run even if a unit is replaced got to.
  • the pressure plates 17 point across to the press belt extending, horizontal guideways 23 on Slidably mounted and lockable on guideways 24 fixed to the frame are.
  • the pressure range of the working pressure in the sealed pressure pads extends up to 20 bar and the temperature range up to 250 ° C.
  • the device operates quietly and is easy to maintain.
  • FIG. 7 and 8 show the reaction zone of a further embodiment a double belt press, specifically in FIG. 7 in idle mode and in Fig. 8 in the press operation.
  • a pressure pad consisting of tubes 26, in which the pressure in the tubes 26 is higher than the pressure in the Hoses 10, which is a pressure pad between the pressure plate 5 and the Form press belt 1.
  • the pressurized hoses 26 make an elastic abutment formed between the printing plate 5 and the printing frame 25, which as an additional Thermal insulation is used and deflections of the printing frame are compensated.
  • the elastic hoses 26, which act on the inside with a pressure medium are, like the tubes 10 extend transversely to the direction of transport 4 of the workpieces and are at the ends through distribution channels connected for the print medium.
  • a roller carpet 27 is provided is endlessly circulating.
  • a elastic hoses 26 existing pressure pad arranged, in which the elastic hoses 26 inside with a pressure medium are acted upon. At the end, the hoses 26 are via distribution channels connected for the print medium.
