Definitions

  • the present invention relates to jet projection machines of water on a tablecloth.
  • Machines of this kind can be used for produce woven and knitted textile products, especially non woven.
  • the machine includes a cylindrical box which has at least one slot extending longitudinally, preferably substantially over the entire generator.
  • the interior of the cylindrical body communicates with means of creating a depression.
  • Training means lead to a perforated support cylinder surrounding the body at a distance from it.
  • a micro-hole sleeve is threaded onto the cylinder and means are provided preventing the sleeve from moving along the cylinder.
  • the sleeve is secured in rotation and in translation of the support cylinder by via a screw connection (holding the sleeve from the outside), by a system of inflatable seals (holding the sleeve from the inside).
  • a injector projects jets of water under pressure towards the face outside of the sleeve.
  • Means are provided for passing a tablecloth on the outside of the sleeve where the water jets are directed there.
  • the invention relates to a machine of the type mentioned above in which the life of the sleeve is greater.
  • the mounting of the sleeve is simplified and it can be made with larger tolerances inside diameter.
  • the sleeve is mounted with the possibility of turning freely on the support cylinder and the means intended to prevent sleeve to move along the support cylinder are means limiting the displacement of the sleeve along the support cylinder, but allowing the rotation of the sleeve on the support cylinder.
  • These latter means may be in particular two radial stops fixed to the support cylinder on the one hand and on the other side of the sleeve.
  • the vacuum in the cylindrical body is in generally between 50 and 500 millibar.
  • the cylindrical box can be in general from 1 to 4 slots which extend over an entire generator.
  • the width of the suction slots is general between 5 and 30 mm.
  • the support cylinder can be a honeycomb, sheet metal cylinder perforated rolled in perforated tube and the support cylinder can be made of steel stainless, bronze, plastic.
  • the sleeve has a percentage of holes which represents from 3% to 25% of its lateral surface. It has a microperforated structure and can be made a thin perforated tube covered with a coarse drainage fabric and a fine surface canvas.
  • the machine shown schematically in Figure 1 includes a cylindrical body 1 driven in rotation by a device 2 for driving belt 3.
  • a perforated support cylinder 4 surrounds the body 1 while being distance from it and is integral in rotation.
  • a 5-hole sleeve is threaded onto the support cylinder 4.
  • a pipe 7 for extracting air and water is connected to a vacuum pump and allows the interior of box 1 to be depression.
  • Two injectors 8 and 9 send water jets respectively under pressure towards the outer face of the sleeve 5.
  • the body 1 has a slot 10 extending following its lower generator. While the support cylinder 4 is returned integral in rotation with the body 1 by shims 11, the sleeve 5 is mounted free to rotate on the support cylinder 4. The inner face of the sleeve 5 can roll freely on the outside of the support cylinder 4. But as shown in Figure 3, stops 12 fixed to the support cylinder 4 prevent the sleeve 5 from moving along the support cylinder 4. A roller 13 makes it possible to pass a sheet N of nonwoven to be consolidated on the outer face of the sleeve 2 at the point where the water jets are directed there.
