Abstract

Cette invention concerne un appareil de séchage et son procédé de fonctionnement, cet appareil étant notamment adapté pour les dépôts collants contenant de l'eau laissés sur des chaussures et/ou la semelle de celles-ci (201) au cours de leur fabrication. Ce procédé comprend principalement deux étapes: au cours de la première étape, la chaussure (201), placée dans une chambre de séchage (110), est exposée, d'une part, aux écoulements d'air dirigés sur une surface supportant le dépôt et, d'autre part, à la chaleur infrarouge diffusée, lors de son passage dans ladite chambre de séchage (110), afin d'éliminer le solvant (eau) du dépôt sans former de peau ou de croûte; au cours de la seconde étape, le dépôt est chauffé au moyen d'un autre élément chauffant infrarouge dans une station de post-séchage (116) située après la chambre de séchage (110) et où ne circule aucun écoulement d'air afin de laisser le dépôt à l'état collant. La chambre de séchage (110) comporte une pluralité de tubes infrarouges (202), convenablement espacés, générant un flux infrarouge uniforme, approximativement plan décalé par rapport au support sur lequel les corps (chaussures) (201) sont transporté(e)s.
