Definitions

  • the present invention relates to machines for producing nonwovens and, more particularly to machines for producing nonwovens comprising a tower or more spun-bonds and possibly one or more melt-blown heads depositing filaments or filaments and fibers (melt layers -blown) in a sheet on an upper strand of a conveyor.
  • the tablecloth thus deposited and still fragile is sent to consolidation by water jets.
  • These machines for producing nonwovens allow only one quality of nonwovens to be obtained for a given supply of the spun-bond tower.
  • the invention remedies this drawback by a machine for producing nonwovens which allows, for the same supply of the spun-bond tower, to obtain nonwovens of different qualities.
  • the invention therefore relates to a machine for producing nonwovens comprising a spun-bond tower depositing filaments in a sheet on an upper strand of a first conveyor, characterized in that a first means of sending is provided.
  • the sheet of the first conveyor to a first consolidation by jets of water on a trajectory having a direction other than that of the upper strand of the first conveyor, and there is provided, downstream in the direction of the upper strand of the first conveyor, a calender and , downstream of this calender, a means of deflecting the calendered sheet of choice either directly towards a unit for applying a product to the sheet, or indirectly, with the interposition of a second consolidation by water jets, to the unit for applying a product to the sheet and a second means is provided for sending the sheet leaving the first consolidation to the second consolidation.
  • the same machine can thus subject the web either to a simple calendering followed by a treatment by the application unit, this treatment being able to consist of an application of surfactants, binders, lubricating agents, blowing agents. , dyes, in a printing, then in a drying and in a winding, either of sending the tablecloth to the calendering then, to the second consolidation and finally to the unit of application, either of sending the tablecloth to the first consolidation, then 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 soften the sheet after it has been calendered or, if it is not calendered, to obtain a complement of a solidification or a perforation or the creation of logos or three-dimensional structures.
  • Each consolidation can be carried out 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 water jets.
  • the deflection means may simply comprise a roller which deflects the sheet bypassing the second consolidation or by passing it there according to whether the sheet is passed around this roll in an arc turning its concavity downwards or downwards. high.
  • the second means of sending the sheet leaving the first consolidation to the second consolidation can be constituted by a second conveyor.
  • the alternative of bypass is obtained or the second consolidation is carried out by not putting, for the bypass, the water jet injectors in operation.
  • This means of expression can 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.
  • the figure is a schematic sectional representation of a machine according to the invention. It comprises a spun-bond tower comprising an extruder of a molten organic polymer supplying a die 1 making it possible to produce a curtain of filaments F, a cooling zone 2 making it possible to obtain at least superficial solidification of the extruded filaments, a device 3 suction in the form of a chamber inside which the curtain of filaments is subjected to the action of high speed air streams which cause the drawing of the filaments, and a diffuser 4 allowing at the outlet of the suction device for deflecting and slowing down the air flow and distributing the filaments F randomly in a sheet deposited on the upper strand 5 of a first endless conveyor 6.
  • the filaments are in the form of a bundle of filaments F, extending perpendicular to the plane of the figure.
  • a horizontal drum 7 is mounted with a device symbolized by the letter A of 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 onto the lateral face of the drum, the sheet of filaments being able to pass in the form of the sheet Ni between the drum 7 and the injectors 8 and thus be consolidated.
  • the jets can have a diameter between 80 and 170 microns.
  • the number of jets per meter can be between 1,000 and 5,000 and the water pressure in the injectors can be between 10 and 400 bar, while the vacuum in the drum 7 can be between minus 20 millibars and less 500 millibars and the drum 7 can be driven at a speed between 1 and 800 m / min.
  • the ply N1 then passes over the upper strand 9 of a second conveyor 10 to go to a second drum 11 of the same structure and the same operation as the drum 7. From the drum 11, the ply passes over a drum 12 fitted like the drum 11 with injectors.
  • the drum 12 is similar to the drum 11 in its structure and in its operation.
  • a deflection roller 14 is provided which, depending on whether the sheet N 2 is passed over the upper part of the roll 14 or on the lower part of this roller 14, deflects the sheet into a sheet 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 expressing humidity, namely a device giving a vacuum of 600 millibar bypassing the drums 11 and 12, while the sheet N 4 passes on these drums 11 and 12 before going like the other sheets Ni and N 3 on the conveyor 15 and from there to an application unit, which may include a station 18 for applying a surfactant and a binder, a drying station 19 and a winding station.
  • an application unit which may include a station 18 for applying a surfactant and a binder, a drying station 19 and a winding station.
  • the dotted lines in the figure show that all the layers Ni to N 4 pass through the application unit.
