Title
(EN) PRODUCTION OF MULTI-PLY CORRUGATED PAPERBOARD
(FR) PRODUCTION DE CARTON ONDULE MULTICOUCHE
Abstract
(EN)
Method and apparatus for producing a multi-ply corrugated paperboard (105) by repeatedly laminating multi-ply corrugated mediums (102, 103) with different pitches and widths between top and bottom liners is disclosed. This invention thins the paperboard and improves the compressive strength of the paperboard so as to substantially reduce the package volume. In the process for producing the multi-ply corrugated paperboard, a first corrugated medium (102) is continuously laminated to a liner (101), thereby forming a single-ply paperboard. The first corrugated medium (102) has predetermined flute pitch and flute peak height. Thereafter, a second corrugated medium (103) is continuously laminated to the single-ply paperboard, thereby forming the multi-ply corrugated paperboard (105) having improved shock absorptivity and compressive strength against a vertical load. The second corrugated medium has optionally selected flute pitch and flute peak height.
(FR)
Cette invention concerne un procédé et un appareil permettant de fabriquer un carton ondulé multicouche (105) en laminant de manière répétée des éléments ondulés multicouches (102, 103) ayant des écartements et des largeurs différents, entre la couche supérieure et la couche inférieure. Cette invention permet d'amincir le carton et d'améliorer sa résistance à la compression de manière à réduire sensiblement le volume de l'emballage. Lors du processus de fabrication de ce carton ondulé multicouche, un premier élément ondulé (102) est laminé de manière continue contre une couche (101), formant ainsi un carton à une seule couche. Le premier élément ondulé (102) possède un écartement entre les cannelures et une hauteur maximale desdites cannelures prédéterminés. Un second élément ondulé (103) est ensuite laminé de manière continue contre le carton à une seule couche, formant ainsi un carton ondulé multicouche (105) possédant de meilleures qualités d'absorption des chocs et de résistance à la compression exercée verticalement par une charge. L'écartement entre les cannelures et la hauteur maximale de celles-ci dans le second élément ondulé peuvent également être choisis.
