Definitions

  • the present invention relates to machines for the production of nonwovens and, more particularly to nonwovens production machines comprising a tower or several spun-bonds and possibly one or more melt-blown heads depositing filaments or filaments and fibers (tablecloths -blown) in a sheet on an upper strand of a conveyor.
  • the tablecloth thus deposited and still fragile is sent to a consolidation by jets of water.
  • the invention overcomes this disadvantage by a machine for producing nonwovens which makes it possible, for the same supply of the spun-bond tower, to obtain nonwovens of different qualities.
  • the subject of the invention is therefore a machine for producing nonwovens comprising a spun-bond tower depositing filaments in a ply on an upper strand of a first conveyor, characterized in that a first means for sending the web of the first conveyor to a first consolidation by jets of water on a path having a direction other than that of the upper run of the first conveyor, and there is provided, downstream in the direction of the upper run of the first conveyor, a calender and downstream of this calender, a means of deflection of the calendered fleece to choose either directly to a unit of application of a product to the sheet, or indirectly, with the interposition of a second consolidation by jets of water, to the unit of application of a product to the web and there is provided a second means for sending the sheet emerging from the first consolidation to the second consolidation.
  • the same machine can thus subject the web to a simple calendering followed by a treatment by the application unit, this treatment may consist of an application of surfactants, binders, lubricating agents, blowing agents , dyes, printing, then drying and winding, or sending the sheet to the calendering and then to the second consolidation and finally to the application unit, or sending the sheet to the first consolidation, then to the second consolidation and finally to the application unit.
  • the first consolidation by water jets is carried out with pressures between 20 and 400 bar
  • the second is carried out with pressures between 50 and 600 bar so as to achieve a softening of the sheet after it has been calendered or, if it is not calendered to obtain a complement a solidification or perforation or creating logos or three-dimensional structures.
  • Each consolidation can be done for example using a drum or a conveyor, with projection of water jets.
  • the first sending means comprises a drum forming part of the device making it possible to carry out the first consolidation by jets of water.
  • the deflection means may simply comprise a roller which deflects the web by bypassing the second consolidation or by passing it through as the web is passed around the roller in an arc turning its concavity downwards or downwards. high.
  • the second means of sending the web leaving the first consolidation to the second consolidation may be constituted by a second conveyor. According to another possibility, one obtains the alternative of bypass or to perform the second consolidation by not putting, for the bypass, the jet injectors of water in operation.
  • a means for expressing the moisture contained in the sheet may be constituted in particular by a third conveyor provided with a device giving a vacuum, giving in particular a vacuum of between 400 and 700 millibar.
  • This expressing means may be constituted in particular by a third conveyor provided with a device giving a vacuum, giving in particular a vacuum of between 400 and 700 millibar.
  • 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 side face of the drum, the sheet of filaments can pass in the form of the sheet N 1 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 less than 20 millibars and less 500 millibars and the drum 7 can be driven at a speed between 1 and 800 m / min.
  • the sheet N1 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 drum 11, the web passes over a drum 12 provided as the drum 11 of injectors.
  • the drum 12 is similar to the drum 11 in its structure and in its operation.
  • a sheet N 1 can be cut and make it go to a sheet N 2 in the same direction as the upper 5 of the conveyor 6 and pass it in a calender 13
  • a deflection roll 14 which, according to whether the sheet N 2 is passed over the upper part of the roll 14 or on the lower part of this roll 14, deflects the sheet into a tablecloth N 3 or in one tablecloth N 4 .
  • the sheet N 3 is sent directly to a third conveyor 15 provided with a device 16 for the expression of moisture, namely a device giving a vacuum of 600 millibar thus bypassing the drums 11 and 12, while the sheet N 4 passes on these drums 11 and 12 before going like the other sheets N 1 and N 3 on the conveyor 15 and thence to an application unit, which may comprise a station 18 for applying a surfactant and a binder, a drying station 19 and a winding station.
  • a device 16 for the expression of moisture namely a device giving a vacuum of 600 millibar thus bypassing the drums 11 and 12, while the sheet N 4 passes on these drums 11 and 12 before going like the other sheets N 1 and N 3 on the conveyor 15 and thence to an application unit, which may comprise a station 18 for applying a surfactant and a binder, a drying station 19 and a winding station.
