Definitions

  • the invention relates to a device for the continuous production of multilayer, flat materials, in which the layered materials are guided between two press belts forming a reaction zone, heated there and pressure is exerted on the layered materials by at least one press belt, this press belt being applied in the reaction zone the side facing away from the layer is assigned at least one pressure chamber which is charged with a gaseous or liquid pressure medium and which cooperates with a pressure plate on the side facing away from the press belt.
  • Continuously operating presses are known (DE-PS 33 13 406), which are provided with at least one endlessly rotating belt which is pressed onto the workpiece by a pressure medium, in which the pressure medium flows into a rectangular pressure chamber adjacent to the pressure belt and sealed by means of a rotating sealing strip can be introduced on the side of the pressure plate facing the press belt, the sealing strip being connected to a correspondingly rectangular mounting frame which is guided in a groove of the pressure plate, is movably mounted inwards and outwards of the groove and is pressure-loaded in the direction of the press strip which slides along the sealing strip.
  • the gap sealed by the sealing strip with respect to the circumferential press belt can, 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 in the width of the workpiece or the like. lead to a loss of pressure medium, which can result in surface defects in the product.
  • pressure medium can flow out through the gap between the sealing strip and the press belt in the event of a malfunction during operation.
  • the invention has for its object to design a device of the type mentioned so that a delimitation of the pressure chamber directly by the press belt and thus a sealing gap between the rotating press belt and the lateral boundary of the pressure chamber is eliminated.
  • the pressure spaces are formed as juxtaposed elastic hoses, which are acted upon with a pressure medium on the inside and which are connected to one another at the end by distributor channels.
  • the pressure chamber can also be on the press belt facing Side be bounded by an elastic membrane, which is fixed at its free edge against the atmosphere absolutely close to the pressure plate. Since the pressure chamber or the pressure chambers are formed by these tightly closed cushions acted upon by the pressure medium, a format change can be carried out on the device on the device without this having an adverse effect on the tightness of the pressure cushions.
  • slide film is arranged as a separate functional part between the pressure pad and the endlessly circulating belt, this slide film, which is a wearing part, can be exchanged in a simple manner.
  • the heat generated due to the friction between the wear foil and the endlessly rotating belt can be used as process heat.
  • the double belt press according to FIG. 1 has endlessly rotating press belts 1, the working strands of which in the reaction zone 2 limit a press nip for the workpiece 3, which passes through the double belt press in the direction of arrow 4.
  • the reaction zone is formed on each side by a pressure plate 5 and a pressure iron 6.
  • the pressure plate 5 is composed of an insulating plate 7 and a heating plate 8.
  • the pressure pad 6 is formed in the exemplary embodiment according to FIGS. 1 to 4 and according to FIG. 6 by self-elastic hoses 10 which extend transversely to the press belts 1, are arranged next to one another and are acted upon on the inside with a pressure medium.
  • This pressure medium can be gaseous or liquid or hydropneumatic.
  • the pressure pad 6 is shown in plan.
  • the interiors of the hoses 10 lying next to one another are connected to one another on the longitudinal sides of the pressure pad by distributor channels 11, so that the pressure medium is introduced into one of these distributor channels, which can be formed by metal parts.
  • the pressure medium can be designed to be standing or to run all round.
  • a sliding film 12 is arranged between the pressure pad 6 and the circumferential press belt 1, which can consist of polytetrafluoroethylene and is fixed on the front end 13 of the pressure plate 5, which extends transversely to the press belt.
  • the setting 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 strand of the press belt 1.
  • FIG. 6 shows an exemplary embodiment in which the sliding film 12 arranged between the pressure pad formed by tubes 10 and the press belt 1 is detachably fastened to both end faces 15, 16 of the pressure plate 17.
  • the sliding film can also be designed as an endless belt that runs around the printing plate.
  • FIG 3 shows a partial section of a double belt press in idle mode, in which the inner spaces of the tubes 10 are filled with a pressure medium, but the tubes 10 are not deformed, and thus limit the press nip.
  • FIG. 4 shows the part of the double belt press according to FIG. 3 in production operation. Due to the thickness of the workpiece 3, which passes through the reaction zone of the double belt press, the inherently elastic hoses 10 are deformed elliptically.
  • Any format of a workpiece can be passed through the reaction zone without leakage and pressure medium flowing into the atmosphere in the area of the pressure pads.
  • FIG. 5 shows an exemplary embodiment in which the pressure space 18 is delimited by an elastic membrane 19, which is at its free edge 20 is fixed close to the pressure plate 5.
  • the working pressure is built up by a pressure medium which is introduced through the pressure plate and which can be gaseous or liquid.
  • a slide film 21 is also arranged between the membrane 19 and the press belt 1 of the belt press.
  • this slide film is releasably attached exclusively to the end face 13 of the pressure plate 5 by means of screws 14.
  • the sliding film can also be designed as an outer layer of the membrane. It can also form an inner coating of the press belt interacting with the pressure chamber.
  • the tubes 10 can also be provided with a sliding layer on the outside, so that the sliding film 12 is omitted.
  • the pressure pad 6 assigned to each press belt 1 and the pressure plate 17 consist of several mutually independent structural units 22, so that the production operation can continue even if a structural unit has to be replaced.
  • the pressure plates 17 have horizontal guide tracks 23 which extend transversely to the press belt and are slidably mounted and lockable on guide tracks 24 fixed to the frame.
  • the pressure range of the working pressure in the sealed pressure cushions 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 of a double belt press, specifically in FIG. 7 in idle mode and in FIG. 8 in press mode.
  • a pressure pad consisting of tubes 26 is arranged between the pressure plate 5 and the pressure frame 25, in which the pressure in the tubes 26 is higher than the pressure in the tubes 10, which form a pressure pad between the pressure plate 5 and the press belt 1 .
  • the pressurized hoses 26 form an elastic abutment between the pressure plate 5 and the pressure frame 25, which serves as additional thermal insulation and compensates for deflections of the pressure frame.
  • a roller carpet 27 is provided between the pressure plate 5 and the press belt 1 and is guided continuously all the way round.
  • a pressure pad Arranged between the pressure plate 5 and the pressure frame 25 is a pressure pad consisting of juxtaposed elastic hoses 26, in which a pressure medium is applied to the inside of the elastic hoses 26. At the end, the hoses 26 are connected via distribution channels for the pressure medium.
