Definitions

  • the layer or sheet of relatively loose fibers on the collecting conveyor is usually then transferred to an apparatus commonly known as a "heat treatment oven for the mattress", in which the latter is transported by additional perforated conveyors, which frequently include two conveyors endless with adjacent strands that are opposite and spaced and used to determine the thickness of the mattress that forms.
  • a heat treatment oven for the mattress in which the latter is transported by additional perforated conveyors, which frequently include two conveyors 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.
  • the main object of the invention is to provide heating for the hardening of the binder by means not only of a primary heating system as generally described above, but also of a second independent heating system comprising at least a pair of relatively small collectors in service in relatively small localized regions on either side of the path of the matelaa, this pair of collectors serving to pass through the mattress a gas heated under a pressure and at a temperature which are high enough to raise the temperature of the core of the mattress to a higher value than that reached by the heart in the regions adjacent to these localized regions.
  • the heated gas from this "secondary" binder curing system is preferably propelled through the mattress into a localized region located in the middle or downstream part of the path, so that the surface layers of the mattress have already been cured. and stabilized by the primary heating system. This initial stabilization of the surface layers of the mattress makes it possible to use a relatively high pressure in the secondary heating system without dislocating the fibers of the mattress.
  • the arrangement according to the invention is adaptable to the treatment of mattresses and plies of fibrous materials of great diversity, but for the reasons indicated above, it is especially advantageous for the curing of the relatively dense mattress binder, because the pressure and temperature conditions maintained in the secondary heating system according to the invention favor 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 exerted after the surface layers of the mattress have been stabilized, rapid penetration is ensured without breaking. fibers.
  • the primary heat treatment system comprises pairs of collectors or boxes of hot air circulation 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 leakage 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 during heat treatment in the localized region of the secondary collectors is very effective in quickly reaching the curing temperature of the binder at the heart of the mattress and one of the aims of The invention is to rapidly reach a curing temperature of the binder which is high enough to initiate the exothermic reaction of the lialite residue.
  • 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 perform 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 reduce short-circuiting to a minimum. and leaks and also automatically allowing the deformation of some of the sealing elements without rupture of these in the case of an accumulation of resin or other deposits on the carriers scrolling the mattress in the oven.

  • 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.

  • Suction fans 17a are connected to the suction boxes.
  • the sheet 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, as a result. between the cylinders R1-R2, the partially calendered mattress is inserted between the strands of the conveyors in the heat treatment oven.

  • the arrangement of the intake ducts and discharge is as indicated above for the pair C, and for the pair F the arrangement is the same as for the caissons D. It is obvious that these relations can be changed for a modification of the behavior of the heat treatment and that different flow conditions can be chosen for products which differ in nature, thickness and / or density, in the usual manner.

  • 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 gyatems quickly bring the temperature of the binder to the value where the exothermic reaction takes place, even at the core of the mattress, and this temperature is then maintained more conveniently even beyond the localized region occupied by the high pressure collectors .
