Abstract
This apparatus uses laser beams in place of existing standard glass chopper units affixed to resin mix heads. Conventional glass choppers use steel blades that eventually wear out or break, adding to maintenance costs. The laser device operates in a manner that allows one to set the pulse rate for the specific purpose of varying the fiber length. During the injection operation, intensity of the laser may be adjusted to accommodate cutting or different sizes and kinds of fibers. The laser apparatus preferably produces long fiber reinforced urethane substrates such as interior door panels for automobile doors.
