Definitions

  • the present invention relates to a process for the manufacture of wet stationery felts in which a web consisting of one or more fiber veils is fixed on at least one of the sides of a canvas.
  • successive layers of fiber veils emerging from a card are deposited directly on the base stretched over the needling machine.
  • the canvas is in continuous motion and passes under the head of needles so that the tablecloth deposited is needled in the canvas immediately.
  • a sheet is prefabricated which will then be deposited on the base and needled on it.
  • the veil of fibers emerging from the card is deposited on a moving carpet which brings the sheet formed of successive layers under the needle head of a pre-needling machine which gives a cohesion making it possible to form a roll of sheets which will be then unrolled on the canvas in the needling machine to form the felt.
  • the method according to the invention making it possible to avoid the use of a deep needling is characterized in that said webs obtained by carding the fibers and possibly pre-needled by a passage through a pre-needling machine having a low needle density are densified by at least three passages in a needling machine with a high density of needles, at least one of the passages ensuring needling in the opposite direction to the others, said ply thus formed being then fixed to the canvas.
  • the sheets thus densified have a very high resistance in the direction of the length and the width.
  • the invention also relates to a machine for densifying the plies, characterized in that it comprises a needling machine with a head with a high density of needles, means for receiving the needled ply at the outlet of the needling machine, comprising a removable roller driven in rotation on which is wound the web leaving the needling machine, means for feeding the needling machine comprising a removable roller identical to the roller disposed at the outlet on which the already needled web can be wound and means in translation to bring this sheet under the head of the needling machine, said output roller can be driven in both directions of rotation.
  • Figure 1 shows a tablecloth densification machine which comprises a needling machine 1, provided with a head 2 of high density needles. This 40 cm wide head will have approximately 3,000 needles per meter of length. Note that in the low density pre-needling machines there are only 1000 needles per meter in length for a head 40 cm wide.
  • the head 2 is arranged above a matrix 3.
  • a mat 4 is used to bring the sheet 5 between head 2 and matrix 3.
  • a roller 6 is arranged driven by motor rollers 7.
  • the needled web 5 is wound around the roller 6.
  • rollers 6 and 8 are removable and identical and the rollers 7 can change the direction of rotation.
  • rollers 9 are also provided at the entrance above the carpet.
  • a pre-needled ply 5 is placed around the roller 8.
  • This ply 5 is unwound between the head 2 and the matrix 3 of the needling machine which also needles, for example the location of the ply.
  • This ply 5 is wound around the roller 6.
  • the roller 6 is dismantled and put in place of the roller 8, the roller 8 which is empty takes the place of the roller 6.
  • a new passage of the tablecloth is made through the needling machine 1 needling this time the reverse side of the tablecloth.
  • the output roller is rotated in the opposite direction (see FIG. 2) so that the third and last pass will allow needling of the reverse side of the web like the second pass.
  • this ply or plies are fixed to a canvas (10) by needling or possibly gluing.
