  • Method For Automatic Setting Of the Rider Roll/Glue Applicator Roll Gap On A Glue Machine
    Publication number: 20140030424
    Abstract: A method for automatically setting the rider roll/glue applicator roll gap for the single face web on a glue machine senses a forward drag that the single face web, operating at corrugator speed, exerts on the glue applicator roll, driven at an underspeed, after bringing the flute tips of the single face web into contact with the glue applicator roll by adjusting the position of the rider roll. Changes in forward drag exerted on the glue applicator roll are monitored and related directly to glue applicator roll drive current to provide a slight compression of the single face web between the rider roll and the glue applicator roll. Preferably, the glue applicator roll uses a regenerative drive and the target drive current command in a feedback control system to cause the gap to be adjusted to achieve the desired slight compression of the web flutes and to maintain the glue applicator roll under speed.
