Definitions

  • the invention relates to a press according to the preamble of the main claim.
  • a press is known from US-A-3 215 065.
  • a continuous press is known (DE-OS 2511 878), in which the belt is deflected into a press nip by means of a roller of large diameter.
  • This press can be designed as a preliminary or finished press.
  • the belt is stretched from the large diameter roller to a deflection roller.
  • an abutment is provided on the back of the belt to support it, which abutment can additionally be provided with a sliding film, with a lubricant being additionally fed and removed between the belt and the sliding film by arrow-shaped grooves.
  • press known (DE-OS 19 38 280).
  • This has press rollers at the inlet end of the press, around which the endless belts are guided.
  • Each of these belts comprises a further, endlessly rotating plate belt, which is also deflected by means of two deflecting rollers.
  • the front of these two deflecting rollers deflecting the plate belts determine the beginning of a further pressing zone; in this area the steel strips run parallel to each other.
  • the press nip is formed from the front press roll of the steel strip to the start of the plate belts.
  • the steel strip is arranged practically in a single plane in this front pressing area and is supported on the back by means of an abutment which is provided with a sliding coating made of a plastic. At right angles to the direction of transport, individual areas of the sliding surface are separated from one another with a transverse joint. In addition, a strip running transversely to the direction of transport is provided in the area of each joint. A liquid lubricant under pressure is supplied to the joint through openings.
  • the sliding surface of this known press also has joints extending perpendicular to the direction of transport and across the entire width of the surface, to which a liquid lubricant is supplied via longitudinal channels.
  • the invention has for its object to form a press with a small size and good efficiency with excellent quality of the processed plate web.
  • the openings provided in the sliding lining not only make it possible to reliably lubricate the entire pressing area, but also to exert a lower pressure of the lubricant with an optimal lubricant throughput, in order to achieve significantly lower friction values and in this way to enable high throughput rates and a reduction in the drive energy required for the press.
  • the invention are also pockets located in the area around each opening of the sliding lining, which move along as a result of the transport speed of the endlessly rotating belt, which surprisingly leads to an extremely extremely low coefficient of friction.
  • the transversely arranged strips are intended to prevent the lubricant from being transported away from the belt, so that, in contrast to the teaching of the invention, the lubricant there is only under a static pressure in the region of the groove, but this does not result in a throughput of one certain amount is achievable.
  • Another advantage is that, because of the higher lubricant throughput, a sufficiently large amount of heat can easily be transferred if the lubricant is previously heated to a certain temperature, so that the amount of heat emitted via the belt is heated and / or set in the fleece to be pressed of the binder, what the goodness and
  • the dimensional accuracy of the plate to be manufactured is influenced favorably. It is even particularly advantageous to construct the sliding pads and abutments modularly and retrofittable; In this case, a butt joint, but not a joint, can occur (if the uninterrupted sliding surface of the press area is formed by lining up the individual modular parts), which would cause the slidability in the press nip to be discontinued abruptly and to a certain extent.
  • a butt joint, but not a joint can occur (if the uninterrupted sliding surface of the press area is formed by lining up the individual modular parts), which would cause the slidability in the press nip to be discontinued abruptly and to a certain extent.
  • the teaching according to the invention forms such a stable sliding film or sliding printing film which, in contrast to the knowledge
  • each groove is assigned a rear opening in the transport direction and a front opening in the transport direction through which the lubricant can be supplied or removed, so that with sufficient pressure not only a stable sliding film between the side of the groove and the edges adjacent projections and the back of the endless belt, but at the same time a sufficient amount of heat transported by the lubricant can be provided for the fleece to be pressed; in the latter case, the lubricant is circulated at a high conveying speed.
  • the width and depth of the groove are dimensioned with regard to the conveying speed of the lubricant, but are preferably substantially wider than deep, so that the lubricant flowing through each groove flows past a relatively large area on the back of the belt for the purpose of heat transfer.
  • the invention thus ensures a high throughput with, at the same time, almost ideally uniform surface pressure on the nonwoven with a simpler and uncomplicated construction of the press, and at the same time the plates produced have good to very good thickness tolerances.
  • the press according to the invention is therefore less expensive to produce and, because of its greater efficiency, results in lower operating costs.
  • the continuously operating press shown in FIG. 1 has an upper, continuously rotating belt 5 and a further, continuously rotating lower belt 6, between which the fleece 7 (FIGS. 3 and 4) is transported according to arrow 8 with simultaneous preliminary and main pressing and calibration .
  • On the back 9 of the belts 5, 6 facing away from the fleece there is a sliding coating 13 in the entire pressing area 10, which consists of a pre-pressing area 11 and a main pressing area as well as a calibration area 12, which is, for example, a rubber vulcanized onto the abutment 14 in the pressing area 10 can.
  • the sliding linings 13 in the pre-pressing area are arranged at an angle to one another to form the press nip, as is shown schematically in FIG.
  • modular sliding lining units can be used, which follow one another angularly offset in the transport direction 8 of the belt until they run parallel to one another in the main pressing area. It is also possible that the sliding coating 13 in the pre-pressing area is continuously and continuously curved up to the beginning of the main pressing area 12.
  • the sliding coating 13 is shown in more detail in FIG. 2. It extends over the entire width 15 and length of the entire press area, of which only the finished press area and calibration area 12 are shown.
  • An opening 16 is provided in the area at the front with respect to the transport direction 8, and an opening 20 is provided in the area at the rear in relation to the transport direction 8, which are located diagonally opposite one another. Both openings 16, 20 each open into a groove 19. Between these two outer grooves, however, a large number of mutually parallel further grooves are provided, two mutually adjacent grooves being connected to one another via a connecting groove 21.
  • a seal surrounding the entire pressing area is not shown for better illustration and for easier understanding.
  • the two openings 16, 20 are arranged at a distance from the lateral boundary of the sliding coating 13 and do not extend there either. Via the openings 16, 20, 22, the lubricant is then fed to the sliding surface 13, which at least in regions has a microfine or greater porosity.
  • a group 19 ′ of a plurality of grooves 19 running parallel to one another is provided, with 8 groups in the transport direction 8 19 'of grooves 19 can be arranged one behind the other such that they are arranged offset with respect to the transport direction 8.
  • each groove 19 is assigned a front and rear opening 16 and 20 in the transport direction 8, through which the lubricant is supplied or removed in the circuit. Front and rear openings 16, 20 are further arranged with respect to the transport direction 8 on different sides of the pressing area. Two mutually adjacent grooves 19 of a group 19 'have a connecting groove 21.
  • the two outer grooves 19 of each group 19 ' are approximately half as large apart from each other from the lateral edge of the pressing area.
  • the distance from the rearmost end of the grooves 19 in the transport direction corresponds approximately to the distance from the lateral boundary.
  • the sliding coating 13 with microfine or greater porosity is elastically shear-deformable as an elastic plastic and extends in one piece without interruption in the respective pressing area over its length viewed in the transport direction 8 of the belt (5, 6).
  • the entire, approximately rectangular press area (10, 15) or the sliding coating 13 is also surrounded by a seal 23, which is formed in one piece and surrounds the entire press area, also in a rectangular shape.
  • This seal consists of an elastic plastic and has a sealing block 24 with an opening 25 for receiving a screw 26 which is screwed into a holding block 27. The head of the screw comes into contact with a vulcanized washer or a flat iron 28 with corresponding screw holes, so that the entire seal is pressed onto the holding block 27.
  • a lip 29 with a sealing edge 30 extends from the sealing block 24 and comes to rest on the underside 9 of the band 6.
  • This lip 29 is pressed tightly against the underside 9 of the band 6 by means of a counter-pressure bearing 31 designed as a plastic band and is inserted in a groove of a holder designated overall by 32, which has a schematically indicated passage 33 to a collective groove designated overall by 34 (Fig. 4).
  • the device for retrofitting known continuous presses which according to the invention can also be configured as a modular unit, is shown in a schematic cross section. It can also be seen from this illustration that the upper belt 5 is wider than the lower belt 6 and has on its underside a wiper 36 which bears against it and wipes off oil creeping over the side edge of the belt.
  • the two abutments 14 and holding blocks 27 and 32 for the seal and the counter-pressure bearing 31 are fixed to a holding plate, designated overall by 38, the inlet and outlet connections for the lubricant to be attached laterally have been omitted for the sake of a simpler illustration.
  • the two holding plates 38 are connected to one another via connecting pieces 39, so that this unit can be used as a whole in other continuously operating presses with a minimum of time and effort as well as adaptation work.
  • FIG. 5 shows a partial section according to FIG. 2.
  • the sliding coating 13 is vulcanized onto the holding plate 38 to form the grooves 19 and the connecting grooves 21 of a group 19 ′ connecting them.
  • a special connecting piece schematically designated by 40 in FIG. 5, can be provided around the opening 16 and 20, which is not described in more detail here.
  • FIG. 6 shows an alternative embodiment to FIG. 2, which is shown in simplified form and is intended to be mirror-symmetrical with respect to the longitudinal plane.
  • grooves 19 are provided which extend parallel to the transport direction 8 and which are connected to one another by an approximately semicircular recess 41 in the front end to the transport direction 8.
