Definitions

  • the present invention relates to a spreader-spreader device intended to cover a web of fibers, in particular non-woven fibers, in particular at the exit of a card device, as well as to a method for controlling a crosslapper this genre.
  • a crosslapper disposed at the exit of a card device producing a fleece of nonwoven fibers comprises a front mat bringing the web of fibers into the spreader-lapper to a moving storage trolley according to a movement back and forth, a rear carpet bringing the accumulated veil by the accumulator carriage to a lapper carriage also movable in a back and forth motion and an exit apron, the accumulator carriage being arranged to send the veil of fibers accumulated towards the lapper carriage and the latter being arranged to deposit the accumulated veil on the apron to obtain a ply composed of layers which are obliquely, alternately in one direction and in the other with respect to the direction in length of the tablecloth.
  • the present invention aims to overcome the drawbacks of the prior art by proposing a spreader-spreader device, in particular arranged at the outlet of a card device producing a web of fibers, in particular of non-woven fabric, comprising a front mat bringing the fiber web in the crosslapper up to an accumulator truck, a rear carpet bringing the accumulated web to a lapper carriage and an exit apron, the storage trolley being arranged to send the fiber web to the trolley lapper, and the latter being arranged to deposit the accumulated veil and returned by the accumulator carriage on the slantwise deck, alternately in one direction and the other, with respect to the lengthwise direction of the sheet, characterized in that the lapper carriage and / or the accumulator carriage is or are driven (s) by respectively a lapper carriage belt and / or accumulator carriage, whose two front and rear ends re are respectively fixed to a front and rear side of the respective carriage.
  • the belt respectively of the lapper carriage and / or the accumulator carriage is driven by a plurality of pulleys, a first pulley of the plurality of pulleys being driven by a first driving motor and a second pulley of the plurality of pulleys being driven by a second motor, the first and second pulleys being mounted on one front side and the other rear side of the lapper carriage and / or the accumulator carriage, in particular the lapper carriage belt is driven by a plurality of pulleys, a first pulley of the plurality of pulleys being driven by a first drive motor and that there is provided a second motor driving a second drive pulley of the plurality of pulleys, different from the first pulley, both first and second pulleys being mounted on either side of the lapper carriage.
  • the belt respectively of the lapper carriage and / or the accumulator carriage is driven by a plurality of pulleys, a first pulley of the plurality of pulleys being driven by a first drive motor and a second pulley of the plurality of pulleys.
  • the drive being driven by a second motor, the first and second pulleys being mounted on one front side and the other rear side of the lapper carriage and / or the accumulator carriage.
  • the storage trolley is driven by an accumulator trolley belt, the two front and rear ends of which are respectively fixed to a front and rear side of the storage trolley.
  • the arrangement according to the invention allows an absorption of the over-lengths which appear in the endless belts forming the front and / or rear mats, in particular by securing, for example by hooking, a respective auxiliary trolley disposed along the synchronous belt of the lapper carriage and / or the storage trolley to a driving roller of the rear carpet and / or the front carpet, in particular by a system of toothed plates acting as a stirrup, instead of stopping the belt or belts (s) on the respective auxiliary carriage to return to the respective lapper or accumulator carriage with a cable, as was the case in the prior art.
  • a respective auxiliary carriage disposed along the respective synchronous belt of the lapper carriage and / or the accumulator carriage is secured to the axis of a drive roller of the rear carpet and / or the front carpet, by a serrated stirrup system for adjusting the attachment position of the axis of the rollers of the auxiliary carriages on the drive belt so as to adjust the travel length of the endless belt.
  • a spreader-lapper 1 according to one embodiment of the invention.
  • This spreader-lapper is arranged downstream of a card producing a veil of non-woven that arrives on a carpet 2 before endless.
  • the front endless belt 2 comprises a section 21 rising slope followed by a horizontal section extending to a trolley 12 accumulator.
  • a simple 2d detour roll around which the front mat 2 performs a half-turn, the back mat 5 recovering the veil 4 after turning the veil to transport it to the lapper carriage 9.
  • the respective movement and / or displacement of the carriages 9 and 12 and the belts 2 and 5 are controlled by a central unit which controls their respective motors according to the kinematic data (position, speed, acceleration) desired for each, these settings defining the parameters (in particular length, orientation of the folds in bias and density density) desired for the final tablecloth.
  • the two carpets 2 and 5 are endless carpets that run in opposite directions from each other.
  • the entrance mat 2 is guided along its travel path by rollers 2a to 2m.
  • the back carpet 5 is guided along its path by rollers 5a to 5m.
  • the rollers are freely rotatable, except those coupled to motor means, as described in the present application.
  • the two mats are driven so as to have in the area of mutual overlap of the web (between the two carriages 9 and 12 and up to deck 3), especially in the vertical passage 17 just before the site 11 of deposit on the water table. in the deck 3, equal speeds corresponding to the desired speed of feeding of the Sail 4 to the site 11 deposition.
  • the front carpet 2 is an endless carpet driven by rollers 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i, 2j, 2k, 21 and 2m. Between the different rollers, sections 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32 and 33 extend which form the carpet 2 as a whole. The sections 21 and 22 bring the veil exiting the cards to the accumulator truck 12.
  • the rear mat extends by being driven by rollers 5b, 5c, 5d, 5e, 5f, 5g, 5h, 5i, 5j, 5k, 5l and 5m.
  • Sections 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61 and 62 extend between two successive rolls and form the backing as a whole.
  • the backing mat 5 supports the fiber web from roll 5e to the deposition site 11.
  • the fiber web is sandwiched between the section 24 of the front carpet and the section 55 of the rear carpet.
  • the accumulator carriage 12 is driven by a belt 80, which extends in a loop from a front end 81 to a rear end 82.
  • the forward end 81 of the belt 80 is attached to the front side of the accumulator carriage 12 while the rear end 82 of the belt 80 is attached to the rear side of the accumulator carriage 12.
  • the belt is driven by pulleys 83, 84, 85, 86 and 87. Between the pulleys 85 and 86, there is disposed along the belt an element 14 forming an auxiliary carriage, which is secured in translation by a toothed plate 70 stirrup office with the axis of roll 2l detour of the carpet 2 before.
  • the driving pulley 84 is rotated by a motor 102.
