Abstract

L'invention a pour objet : - un procédé de séchage et de polymérisation des liants de bandes continues constituées de nappes ou matelas de fibres isolantes entre deux convoyeurs à bandes perforées placés dans une étuve à l'intérieur de laquelle on fait circuler à faible vitesse des gaz à température voulue, dans lequel on ajoute à cette circulation lente une circulation complémentaire forcée ou circulation rapide, en aspirant localement les gaz sur une face du matelas à l'intérieur de l'enceinte pour les réinjecter sur sa face opposée sous une différence de pression relativement élevée; - une étuve de chauffage constituée de caissons pressurisés traversés par au moins deux convoyeurs complémentaires de transport et de calibrage à palettes perforées entre lesquels on fait circuler à faible vitesse des gaz à température voulue, comprenant deux caissons auxiliaires 40 placés à l'intérieur des caissons principaux 21 à 26 et disposés transversalement à la direction d'avancement des convoyeurs 1 de part et d'autre de la trajectoire de ces derniers, le long de la face arrière des palettes 9, ces caissons étant reliés l'un à l'admission, l'autre à la sortie d'un ventilateur de recyclage.The subject of the invention is: a process for drying and polymerizing the binders of continuous bands made up of sheets or mattresses of insulating fibers between two conveyors with perforated bands placed in an oven inside which is circulated at low speed gases at the desired temperature, in which is added to this slow circulation a complementary forced circulation or rapid circulation, by locally sucking the gases on one face of the mattress inside the chamber to reinject them on its opposite face under a difference relatively high pressure; a heating oven consisting of pressurized boxes crossed by at least two complementary transport and calibration conveyors with perforated pallets between which gases are circulated at low speed at the desired temperature, comprising two auxiliary boxes 40 placed inside the boxes main 21 to 26 and arranged transversely to the direction of advance of the conveyors 1 on either side of the path of the latter, along the rear face of the pallets 9, these boxes being connected one to the inlet , the other at the outlet of a recycling fan.
