METHOD AND DEVICE FOR MAKING A WEB OF CORRUGATED BOARD

摘要

A process for producing a strip (4) of corrugated cardboard by gluing one or more sheets (8, 10) of single-face corrugated cardboard and a sheet (6) of covering paper. At least the corrugations of the upper sheet (10) are heated by means of an infra-red radiation panel (40), after the glue has been deposited on them in the gluer (1) and before the sheets come in contact with one another in the double-face machine (2).
