Definitions

  • the invention relates to a device for direct or indirect application of liquid to pasty suspensions, especially for color pigments or starches containing Suspensions on paper or board webs.
  • a paper or board web suspension which may be a glue or dye suspension, but also a pasty coating composition, applied from an application chamber either directly or indirectly via a mostly rubberized applicator roll on the web to be coated and subsequently by means of a roller blade or a Spreading blade metered and fed to a press nip.
  • a size press for direct coating of the paper web is described in which the glue suspension is applied from an open application chamber to the paper web and subsequently metered by means of a corrugated roller doctor blade.
  • This device is not suitable as an open system, especially when suspensions of high viscosity to be processed at the high working speeds of more than 800 m / min currently used for coating, since then no uniform film can be produced on the paper web.
  • DE 44 14 921 A1 a device for the indirect application of a liquid suspension is known, in which the liquid suspension by means of one over the entire width the web-reaching nozzle applicator applied to an applicator roll and finely dosed by means of a doctor bed. In a press nip formed between the applicator roll and a press roll, the coating of the paper web takes place. Also in this commissioned work, the disadvantages mentioned in the device according to DE 34 17 487 A1 occur. Furthermore, DE 44 32 177 A1 describes a device for direct or indirect application of a liquid to pasty suspension onto a moving material web. This device has a metering gap designed as a free-jet nozzle, to which the suspension to be applied is fed via a distributor tube.
  • the metering gap of this device is formed from two lips extending over the web width.
  • Such a device can be used for much higher operating speeds, since the suspension to be applied in this device can be supplied under pressure. However, the increased pressure causes the nozzle gap to expand, in particular in the middle region of the material web, thus leading to an increased application and thus to an uneven line pattern over the web width. This will not be completely eliminated by a downstream doctor, as a bending of the doctor bed can not be prevented.
  • adjustment elements arranged in sections at the gap lips are provided in this device, via which the gap width and thus the flow rate can be influenced.
  • servomotors are provided, which ensure via the measurement of the applied layer and a control loop that the layer remains constant over the entire web width.
  • the cost of producing such a device is very high.
  • such a control circuit with its many elements on a considerable susceptibility to interference is described in DE 198 01 140 A1, which has a complex control system for achieving a uniform line pattern.
  • the aim of the invention is to provide a simple Applicator especially for high speeds working coating systems for direct or indirect application of liquid to pasty To provide suspensions on paper or board webs, with it without complex adjustment and control devices possible, a uniform streak-free Coating also from wide paper or board webs too enable.
  • the task of the Invention solved with the features of claim 1.
  • Advantageous embodiments of the device are in the Subclaims specified.
  • the device according to the invention is a surprise good uniform line image of the applied Suspension over the entire width of the paper or Cardboard web reached without being affected by the between the individual outlet openings existing webs of the diffuser block a stripe image is recognizable in line order. Also, the suspension order across the entire width the paper or board web very evenly. A permanent one Measurement of the suspension order and subsequent corrective adjustment of the order gap or the supplied amount of suspension is unnecessary, so that the Cost of such a device according to the invention can be kept low.
  • FIG. 1 is a sectional view the device according to the invention for indirect Apply thick glue.
  • FIG. 1 In the figure is a cross section through the device shown.
  • the device is attached to the crossbeam 1, in which also the feed tube 2 for the applied Glue is arranged.
  • the feed tube 2 In the feed tube 2 are over the entire Width of the non-illustrated to be coated Paper web arranged a variety of outlets 3 which mediated by bars 4 and the Screw 5 are connected to the diffuser block 6.
  • the diffuser block 6 consists of a variety of individual diffusers whose round inlet cross-section continuously to a rectangular outlet cross-section extended. The walls between each one Diffusers run out on the output side pointed, so that on these spots no vortex generated in the glue suspension become.
  • the further guidance of the glue suspension is on the transfer roller 9 side facing the Ensures diffuser block 6 through the diffuser lip 7.
  • the glue suspension is passed to the doctor bed 10.
  • the doctor bed 10 of the roller blade 11 is arranged, which is in operative connection with the transfer roller 9.
  • a not shown corrugation is introduced in the direction of its longitudinal axis.
  • the clamping device 14 fixes the doctor bed 10 between the crossbar 1 and the hose holder 13. With the pressure hose 12, the fine pressing of the roller blade 11 and thus the thickness of the glue layer to be applied is adjustable. About a separate pivot point, not shown, the adjustment of the overflow gap 8 is possible.
