Definitions

  • the drying of the running web is rather important if the web is coated with a coating substance, which includes water as the fluency element.
  • a coating substance which includes water as the fluency element.
  • water maintains the fluency property of the substance and, hence, faciliates an incomplicated and easy working phase.
  • a commonly used substance concentration includes about 40% of water, which must be removed from the levelled coating layer and the running web, in which a portion of the water amount has penetrated.
  • a typical method to dry the web is to blow air streams either against or parallel to the web so, that the web is maintained contactless from air stream supply boxes, and preferably at a predetermined fixed distance from them.
  • Unit 8 can also be in co-operation with a reflector 14 so that web 3 is running between unit 8 and reflector 14.
  • web 3 is pre- and posttreated with a measure, which accelerates the vapour motion away from the vicinity of the web, which in turn decreases the saturation level near the web.

Abstract

L'agencement décrit sert à sécher une bande de papier en mouvement (3) par traitement thermique. Le traitement est effectué au moyen de sources émettrices de chaleur qui comprennent des unités thermiques séparées (8) pour l'émission de longueurs d'onde comprises dans des spectres de lumière infrarouge. L'unité thermique (8) est munie d'éléments réflecteurs de lumière. Cette unité thermique (8) comprend un élément de corps fermé en forme de boîte (18), qui s'étend sur la longueur transversale de la bande. L'unité de lampe (1) émettant des rayons infrarouges est placée dans cet élément de corps (18), tout comme les éléments d'admission (7) et d'émission d'air ainsi que les éléments de guidage (24; 6) qui servent à faire circuler les flux d'air à travers l'unité thermique (8) et à guider les flux d'air chauffés dans un espace situé entre l'unité thermique (8) et la bande en mouvement (3). L'élément d'admission (7) est relié à une source d'alimentation en air. L'élément de corps (18) comprend un élément en forme de plaque (6) faisant obstacle et placé entre la bande et l'unité de lampe émettrice (1). L'élément faisant obstacle (6) sert à empêcher l'air de s'écouler depuis l'intérieur (23) du corps en direction de la bande et laisse passer les longueurs d'onde de lumière infrarouge. La source d'alimentation en air, les éléments de guidage (24; 6) et l'élément faisant obstacle (6) sont disposés de façon à coopérer les uns avec les autres, permettant ainsi à l'air qui s'écoule entre la bande en mouvement (3) et l'élément obstacle (6) de produire un effet de coussin d'air, un effet Coanda ou similaire.
