ABSTRACT:
A no-crush roll system for attaining zero crush across the double backer in a corrugator is disclosed which is retrofittable to most existing machines. The no-crush roll system includes a series of pairs of bearing adapters each formed with a pin received in an overhead support frame with a bearing support cup located at inwardly extending ends of the pin to receive a bearing mounted to opposite ends of the roller. Each bearing is received in an elongate cavity facing the roller which permits the height of the roller to self adjust in response to changes in thickness of the cardboard material being conveyed along a hot plate as the weight of the rollers pressing against the top surface of the cardboard ensure even glue distribution and curing contact without crushing the material. A method of eliminating crush in a double backer of a corrugator is also disclosed.
