MAG Industrial Automation Systems (Hebron, Ky.) has introduced its Fiber Cut Unit, a system designed to receive from creels and then chop glass, carbon, polyester, aramid or natural fibers. Fiber tows are supplied to the cutting modules (pat. pend.) by two feeding units that can be operated at different velocities. The cutting unit has a modular design and consists of two or more spindle modules, allowing four cuts per rotation and module. After they are cut, the fibers drop onto a velocity-controlled conveyor belt, creating a defined, homogenous spread pattern for a fiber mat. The system can cut and dose various fiber types and two lengths simultaneously, depending on the fiber feed rate and the spindle speed, each of which can be adjusted individually.
