Definitions

  • the present invention relates to machines for producing nonwovens comprising one or more spun-bond towers and possibly one or more melt-blown heads depositing filaments and possibly fibers in a web on a conveyor.
  • the tablecloth thus deposited and still fragile is then sent to consolidation by water jets.
  • a disadvantage of these machines is that the sheet that comes out can not be sent continuously to a product application unit.
  • the invention overcomes this disadvantage.
  • the subject of the invention is therefore a machine for producing a continuous nonwoven, comprising a spun-bond tower depositing filaments in a sheet on a conveyor and a device for consolidating the sheet, characterized by a means for expressing the moisture downstream, in the direction of movement of the web, the consolidation device and by a device for applying a product to the web downstream of the squeezing means.
  • the expressing means is constituted simply by a second conveyor on which the web passes and between the upper and lower strands of which is formed a vacuum device, giving in particular a vacuum of between 40 and 700 millibar, subjecting the web to an effect of suction.
  • the upper run of the second conveyor is given such length, depending on the speed of passage of the sheet, that the moisture content of the sheet becomes less than 70% by weight, and better still less than 50% and even better still less than 20% at the exit of the second conveyor.
  • This moisture content is in general between 10% and 70% by weight. Unlike what a drying would give, it is greater than 10%.
  • the residence time of the web on the second conveyor can be less than 2 seconds for a conveyor whose upper run has a length of 2 m for example.
  • the machine may comprise, downstream of the device for applying a product, a device for drying the sheet, this drying device being able to be made less consequent by the fact that a good part of the moisture has already been expressed in the means of expression.
  • the product application device is preferably a device for applying to the foam, or to the nap roller or by spraying which accommodate a residual moisture content of the web.
  • the application is made by longitudinal strips, which creates an alternation of longitudinal hydrophilic and hydrophobic zones for example.
  • the figure is a schematic representation in section of a machine according to the invention.
  • a spun-bond tower comprising an extruder of a molten organic polymer feeding a die 1 for producing a curtain of filaments F, a cooling zone 2 for obtaining the at least superficial solidification of the extruded filaments, a device 3 in the form of a chamber inside which the curtain of filaments is subjected to the action of high velocity air streams which cause the drawing of the filaments, and a diffuser 4 allowing the exit of the suction device to deflect and slow down the flow of air and to distribute the filaments F randomly in a web depositing on the upper strand of a first conveyor 6 endless.
  • the filaments are in the form of a bundle of filaments F, extending perpendicular to the plane of the figure.
  • a horizontal drum 7 with a device symbolized by the letter A depression inside.
  • the lateral surface of the drum 7 is perforated.
  • the drum is rotated relative to its axis.
  • the drum is surrounded by a perforated sleeve.
  • Two injectors 8 project jets of water under pressure on the lateral face of the drum, the sheet of filaments can pass between the drum 7 and the injectors 8 and be consolidated.
  • the jets can have a diameter of between 80 and 170 microns.
  • the number of jets per meter can be between 1000 and 5000 and the water pressure in the injectors can be between 10 and 400 bar, while the depression in the drum 7 can be between minus 20 millibar and less.
  • the drum 7 can be driven at a speed between 1 and 400 m / min.
  • the sheet then passes on the upper strand 9 of a second conveyor 10 to go to a second drum 11 of the same structure and operation as the drum 7. From the drum 11, the sheet passes over a drum 12 provided as the drum 11 injectors.
  • the drum 12 is similar to the drum 11 in its structure and in its operation.
  • the web is sent directly to a second conveyor 15 provided with a device 16 for the expression of moisture, namely a box in which there is a vacuum of 600 millibar and interposed between the upper and the lower side.
  • a device 16 for the expression of moisture namely a box in which there is a vacuum of 600 millibar and interposed between the upper and the lower side.
  • the upper face of the box has a slot extending transversely facing the entire sheet passing over the conveyor and through which the moisture thereof is sucked.
  • the upper strand has a length of 3 m.
  • the sheet passes there at a speed of 200 m per minute.
  • a device 17 for applying a product of ennoblement which comprises a station 18 proper application of the product, a drying station 19 and a post 20 of winding.
