Abstract
Official abstract text for this publication.
Described is the use of synthetic adhesives in the manufacture of corrugated fiberboard at relatively low temperatures and high lineal speeds. The corrugated fiberboard includes a corrugated sheet of paper and a flat linerboard and the corrugation of the corrugated sheet of paper is produced at paper temperatures below 95° C. and at a lineal speed above 150 m/min. The production of the corrugation of a corrugated sheet of paper is immediately followed by a continuous operation in which a preferably unheated corrugated board adhesive is applied and the corrugated sheet of paper is adhered to at least one first linerboard. The corrugated board adhesive used is an aqueous adhesive dispersion based on at least one synthetic, dispersed polymer having preferably more than 40% by weight solids content, selected from acrylate copolymers, copolymers of vinylaromatics and conjugated aliphatic dienes and vinyl acetate-alkylene copolymers, wherein the glass transition temperatures of the polymers are above 20° C. and (preferably at least 5° C.) below the surface temperature of the corrugated sheet of paper to which they are applied.
First claim
Opening claim text (preview).
We claim: 1. A method of manufacturing a corrugated fiberboard wherein the corrugated fiberboard includes at least one corrugated sheet of paper and at least one flat linerboard, said method comprising corrugating a sheet of paper at paper temperatures below 95° C. and at a lineal speed of above 150 m/min; applying a corrugated board adhesive to the corrugated sheet of paper in a continuous operation immediately after production of the corrugation of the corrugated sheet of pape…
