Title
(EN) VACUUM ASSISTED WEB DRIVE FOR CORRUGATOR DOUBLE BACKER
(FR) ENTRAINEMENT DE BANDES SOUS VIDE DANS UNE MACHINE A CARTON ONDULE DOUBLE FACE
Abstract
(EN)
A double backer (10) for curing the web bonding adhesive and drying the corrugated paperboard web (11) utilizes a web holddown apparatus for maintaining the web in intimate drying contact with the lower heating units which does not require the use of a driven holddown belt. The web is pulled through the double backer (10) by a downstream vacuum conveyor section (23) comprising a single full width belt (92) to the upper surfaces of which a vacuum is applied. The vacuum drive belt (92) has low friction strips (2, 7) on the underside by which the belt is supported on vacuum plenum support surfaces (97) and a unique pattern of vacuum distribution channels (105) on the other side of the belt which together reduce friction and drive power requirements.
(FR)
L'invention concerne une machine à carton ondulé double face (10) assurant le durcissement de l'adhésif de liaison entre les bandes et le séchage de la bande de carton ondulé (11) à l'aide d'un système de maintien qui met la bande en contact étroit avec les unités de séchage à chaud situées au niveau inférieur, sans recourir à une courroie de maintien entraînée. La bande passe dans la machine (10) par une section transporteuse sous vide (23), montée en aval comportant une courroie unique pleine largeur (92) dont la surface supérieure est soumise à une dépression. Le dessous de cette courroie d'entraînement (92) présente des bandelettes à faible frottement (2,7) qui reposent elles-mêmes sur les surfaces d'appui du répartiteur de vide (97). Ces surfaces, combinées à un réseau unique de voies sous vide (105), de l'autre côté de la courroie, réduisent à la fois le frottement et les besoins en puissance d'entraînement.
