  • Machine for producing a corrugated cardboard sheet and process for calibrating the glue gap of such a machine
    Patent number: 6692602
    Abstract: A machine for producing corrugated cardboard incorporates a corrugating roll and a glue roll extending parallel to the former in such a way that a glue gap is formed between the two. To adjust the glue gap, the bearing of the glue roll is pushed against the bearing of the corrugating roll with a contact-pressure force A. By means of an adjusting unit the distance of the two bearings is reduced until the force of the bearing contact pressure, which is measured by a force measuring unit, decreases due to a contact occuring between the glue roll and the corrugating roll. The glue roll may have stop rings at its ends to prevent a direct contact between the glue roll and the corrugating roll.
