Title (EN) ON-LINE SIZING OF CORRUGATED PAPER
(FR) COLLAGE DIRECT POUR PAPIER ONDULE
Abstract:
(EN) A process and apparatus for sizing corrugating material (30) for use between a pair of spaced apart linerboards (91, 92) to produce a corrugated containerboard (39) whereby corrugating material (30) is wetted on one or both sides with a coating of an environmentally friendly sizing curable sizing agent prior to application of an adhesive for gluing the linerboard (91, 92) onto the material. The sizing agent is subsequently cured and migrates through the corrugated medium structure.
(FR) L'invention concerne un procédé et un dispositif pour le collage de matériau de cannelure (30) destiné à être utilisé entre une paire de cartonnettes espacées (91, 92) dans la fabrication d'une caisse en carton ondulé (39). Le matériau de cannelure (30) est mouillé sur l'un des deux côtés au moyen d'un revêtement à base d'agent de collage durcissable sans danger pour l'environnement, avant l'application d'un adhésif pour le collage des cartonnettes (91, 92) sur le matériau proprement dit. L'agent de collage est ensuite durci et migre à travers la structure du matériau ondulé.
