Abstract

A machine for feeding and cutting sheet material includes a housing and a framework pivoted on the housing to permit loading of sheet material into the machine. A feed roll is journalled in the housing. A cooperating pressure roll is journalled on the framework. A spring is adjustably carried on the framework for adjusting the pressure of the pressure roll toward the feed roll. A knife blade on the framework, and fixed to the framework cooperates with a movable knife blade in the housing for cutting predetermined lengths of sheet material. A cam follower bearing is provided in the housing to help guide movement of the knife blade in the housing. A spring adjustment is provided in the linkage connecting the cylinder driving the movable knife blade and the movable knife blade for varying the force of the movable knife blade against the cam roller bearing. A safety interlock in circuit with the drive motor for the feed roll will stop the drive motor when there is a jam of sheet material in the machine in use or if the framework is open.
