Definitions

  • the layer or layer of relatively loose fibers on the collecting conveyor is usually then transferred to an apparatus commonly known as an "oven for heat treatment of the mattress", in which the latter is transported by additional perforated transporters, which frequently include two transporters endless with adjacent strands that are opposite and spaced and used to determine the thickness of the mattress that forms.
  • an apparatus commonly known as an "oven for heat treatment of the mattress”
  • the latter is transported by additional perforated transporters, which frequently include two transporters endless with adjacent strands that are opposite and spaced and used to determine the thickness of the mattress that forms.
  • Such a mattress can be more or less dense depending on the degree of compression exerted by the two carriers in the oven.
  • the mattress is subjected to a heat treatment which causes the binder for the fibers to harden and thus stabilize the mattress at the desired thickness.
  • ovens such as those described in American patent 3 096 161, include, in addition to some of the elements described in American patent 2 997 096, dielectrically heated plates, whose action combines with that of air currents hot to evacuate from the mattress kept in form the excess moisture of the binder, prior to the complete hardening of the latter.
  • the invention consists, over a small part of the total distance of the treatment of the mattress in the oven, in adding to the general forced circulation of gases from one face to the other of the product, or primary circulation, a second forced circulation , under relatively high pressure, therefore at a higher specific flow rate, or secondary circulation, by locally aspirating the gases on one face of the mattress inside the enclosure to reinject them on its opposite face, preferably opposite the area suction.
  • This high-speed recycling takes place in a well-defined region, for example that where the reactions of the curing of the binder are already sufficiently advanced for the mattress to have acquired sufficient surface resistance, this in order to accelerate the heat exchanges and in particular to modify the temperature within the product to speed up the treatment.
  • the arrangement according to the invention is adaptable to the treatment of mattresses and plies of fibrous materials of great diversity, but it is especially advantageous for the curing of the binder of relatively dense mattresses, because the conditions of pressure and temperature maintained in the secondary heating system according to the invention promote rapid penetration of heat inside a fibrous product, even relatively dense and thick, and the fact that the effect of secondary air under high pressure is exercised after the surface layers of the mattress have been stabilized, rapid penetration is ensured without breaking the fibers.
  • the primary heat treatment system comprises pairs of collectors or hot air circulation boxes arranged in succession along the path in the oven
  • the heated air of the secondary system operating in the localized region is under a pressure higher than that of the air used in the primary system.
  • the primary air circulation system serves not only to provide the heat necessary for the curing of the binder, but also as a means to prevent leaks or dissipation to the atmosphere of the air escaping from the secondary system operating under higher pressure.
  • the rapid penetration of heat inside the mattress being treated thermal in the localized region of the secondary collectors is very effective in quickly reaching the curing temperature of the binder at the core of the mattress and one of the aims of the invention is to quickly reach a curing temperature of the binder which is sufficiently high initiating the exothermic reaction of the binder resin.
  • the establishment of this exothermic temperature causes the hardening of the binder to continue, even if the subsequent zones of the oven are not maintained at this same high temperature. Consequently, for the whole of the heat treatment, the use of the secondary high-pressure system in the localized regions of heat treatment downstream leads to an overall saving on the total amount of fuel spent to carry out the heat treatment.
  • Another object of the invention is to provide new arrangements for introducing the high pressure manifolds of the secondary system into the localized regions of the circulation boxes of the primary system, these arrangements making it possible to minimize short-circuiting and leaks and also automatically allowing the deformation of some of the sealing elements without breaking them in the event of an accumulation of resin or other deposits on the conveyors running the mattress through the oven.

  • Each of the conveyors is constituted by a number of pallets which are articulated with one another and carry rollers 12 suitable for running on the rolling tracks 13. The pallets carry transverse ribs 11. Transporters of this kind are driven by sprockets.
  • the gypsies 9, as well as the raceways 13 for the upper conveyor, are mounted in a chassis 14 made of side members and cross members assembled, so that the position of the upper conveyor can be adjusted relative to that of the lower conveyor.
  • This adjustment can be made using screw jacks 15 in a conventional manner which does not therefore fall within the scope of the invention.
  • the distance between the strands 8a and 10a of the conveyors, which are the strands in contact with the fiber mat, can be modified to impose the desired density or thickness on the product being manufacturing.

  • Suction boxes, as illustrated in 17, can be used to promote the collection of fibers and their retention in place on the conveyor.
  • Suction fans 17a are connected to the suction boxes.
  • the layer of fibers carried by the conveyor 16 is brought to the calender cylinders R1-R2, which are preferably adjustable so that it is possible to impose the thickness of the mattress entering the oven and, at the exit between the cylinders Rl-R2, the partially calendered mattress fits between the strands of the conveyors in the heat treatment oven.

It should be noted that, in the first pair of boxes A, the inlet flue 20 is formed in the lower box 18 on the upstream side of the box relative to the direction of travel of the product in the oven and that the discharge flue is formed in the upper box 19 of this pair, near the downstream end.

Pivots and similar stops are provided for the lower partitions 48, but due to the fact that they are driven back downwards by obstacles encountered when the conveyor strand passes into the high pressure system, the return of the partitions 48 to their normal service position is ensured by the springs rather than gravity.

  • the use according to the invention of a high pressure air circulation system and a low pressure air circulation system is particularly effective in various respects, in particular because the hardening of a binder determined can be performed in a smaller number of treatment zones and on a significantly shorter path in the oven. This is due to the fact that high pressure systems are particularly effective in bringing the core of the mattress to the heat treatment temperature in a short time. Another advantage is that high pressure systems quickly bring the temperature of the binder to the value where the exothermic reaction takes place, even at the heart of the mattress, and this temperature is then maintained more conveniently even beyond the occupied localized region. by high pressure collectors.
