Definitions

  • the present invention relates to a universal method for manufacturing a sheet which is completely or incompletely perforated, that is to say in particular a sheet pierced with multiple perforations, or else a sheet having, at the end of the operation, a design with intaglio or relief patterns.
  • this new process can be used on a sheet of any material, which can be, in particular, a paper, a cardboard, a nonwoven fabric, a film, or a plastic plate, or even a sheet of wood or plywood.
  • the invention also relates to new industrial products obtained according to this method, and having original characteristics which it is not possible to obtain with known traditional methods.
  • the object of the present invention is to avoid these drawbacks by providing a practically universal machine for the production of papers, non-woven fabrics, textiles or plastic films which are perforated or have intaglio or raised patterns.
  • a device comprises a support fabric for the sheet material to be treated to be treated which advances with the material under a rotating perforated cylinder, inside which is arranged a fixed water injector oriented transversely to project pressurized water through the perforations of the cylinder in the direction of the sheet to be treated, and it is characterized in that the hydraulic injector comprises, on the one hand a high pressure water inlet chamber which discharges the water against a perforated plate whose holes define needles of water then directed opposite cylinder holes, on the other hand, under the sheet to be treated, a suction box for the water having passed through said sheet.
  • the needles are arranged opposite the holes of the cylinder, offset along one or more generatrices thereof, so as to be the most spaced from each other, on the one hand, to avoid , as much as possible, parasitic phenomena due to the reflection of water on the solid parts of the cylinder, on the other hand, to limit the water flow.
  • the diameter of the holes in the perforated plate is between 50 and 500 microns.
  • a perforated plate pierced with holes arranged according to several distinct generatrices the holes in the plate being always located opposite those of the cylinder, so that the water emitted by the injector completely covers the width of the holes in the cylinder.
  • the injector comprises a device for holding the perforated plate, making it easy to remove it from the body of the injector: the perforated plate is applied strongly against the main body of the injector thanks to the action of hydraulic cylinders which pull the plate upwards via a set of lifting beams and tie rods arranged along the injector.
  • a seal located between the perforated plate and the main injector body makes it possible to seal the assembly. It suffices to release the oil pressure in the hydraulic cylinders, to release the clamping jaws of the perforated plate which it is then possible to extract very easily, by pulling it in the longitudinal direction of the injector, c ' that is to say transversely to the direction of advancement of the sheet material.
  • the water pressure in the main body of the injector is between 2 and 500 bars depending on whether the material to be treated is more or less thick and must be perforated, or simply marked with a water jet.
  • the perforated cylinder can be in contact with the sheet to be treated or be detached from it so that its speed of rotation can be independent of the speed of movement of the sheet, the rotation being able to possibly take place in the opposite direction to that of the sheet scrolling.
  • the perforated cylinder can be of any type, stainless steel, bronze, or even nickel. This list is not exhaustive: it can also be of the same type, for example, as the well-known screen printing cylinders used in textile printing or the deposits of plastic material in relief on floor coverings: the only limit is its mechanical resistance nique to the action of the needles of water emitted by the hydraulic injector.
  • FIG. 1 shows a sheet 1, for example of a nonwoven fabric, which advances in the longitudinal direction represented by the arrow 2.
  • the fixed elongated body 3 of an injector in which a water chamber 4 is defined.
  • the lower bottom thereof is constituted by a plate 5, on which micro-perforations 6 are made, which will each define a water needle 7.
  • Two longitudinal jaws 8 and 9 are subjected to the action of hydraulic cylinders such as 10, to clamp and tighten the longitudinal edges (perpendicular to the arrow 2), of the plate 5 against the body 3 of the injector. the sealing of the mounting of the plate 5 against the injector body 3, when the assembly is in service.
  • This water chamber 4 is, for example, surmounted by a water supply chamber 12, with which it comlunique by large holes 13.
  • the hydraulic injector 3 - 5 - 8 - 9 is mounted in a fixed position inside a rotary cylinder 14, on the thin wall 15 of which are distributed orifices 16.
  • the wall 15 of the cylinder 14 can be at a certain distance 17 above the upper face of the sheet 1.
  • the tangential speed of the rotary cylinder 14 (arrow 18) is independent of the speed of advance of the sheet 1 (arrow 2).
  • An 18 g / m2 non-woven sheet obtained by the so-called "wet process” is supported by a bronze fabric of knitting type, comprising 32 threads in the warp direction, and 27 threads in the weft direction. This sheet is subjected to the action of the device shown in Figures 2 and 3.
  • the perforated cylinder 14 has holes 16 of rectangular section 0.8 mm in the axial direction (arrow 19) and 1.3 mm in the tangential direction (arrow 20), the distance between these holes being 0.8 mm in both directions.
  • the thickness of the cylinder is 0.4 mm and the section of the holes is identical inside and outside the cylinder.
  • the hydraulic injector comprises a perforated plate 0.3 mm thick comprising three rows of holes 0.28 mm in diameter spaced 1.6 mm (from axis to axis) along a generator, and 1 mm between the generators (see Figure 3).
  • the water pressure in the injector is 3.5 bars (chambers 4 and 12).
  • the cylinder is held at 0.5 mm above the sheet 1 and its tangential speed of rotation (arrow 18) is equal to the speed of advancement of the sheet 1 (arrow 2).
  • a plastic sheet 30 microns thick is subjected to the action of the above device.
  • Sheet 1 is placed on a stainless steel support fabric of the "plain" type, comprising 7 threads per cm, in the warp and weft directions.
  • the perforated plate 5 of the injector has a single row of holes 6, 0.12 mm in diameter, spaced from each other by 1.6 mm.
  • the perforated plate 5 is positioned so that the water needles 7 are located approximately in the middle of the orifices 16 of the perforated cylinder 14.
  • the water pressure in the injector is 150 bars and the treatment speed 25 meters / min.
  • the cylinder is located 1 mm above the fabric (interval 17), and its tangential speed of rotation (arrow 18) is equal to the speed of advance of the sheet 1 and its fabric (arrow 2).
  • the plastic sheet 1 is perforated in the form of thin rectangular slots, 0.8 mm in length and non-measurable width.
  • the resistance in the transverse direction of the sheet 1 is considerably reduced, and its porosity is greatly increased.
  • the sheet 1 subjected to a jet of water is no longer waterproof.
  • the same sheet 1 is subjected to a similar treatment.
  • the only difference with the previous treatment is the speed of rotation of the cylinder 14 which gives a vi tangential tesse (arrow 18) of 120 meters per minute (about five times the speed of advancement of sheet 1 (arrow 2).
  • the plastic sheet 1 is now punctured by a multitude of small holes whose dimensions are not measurable.
  • the air permeability of the sheet is excellent, and its transverse resistance is little affected.
  • the sheet subjected to a jet of water also remains waterproof. Finally, the plastic film has lost its characteristic "sound".
