INVENTION: METHOD AND APPARATUS FOR ELIMINATING CUTTING BEAM FLASHBACK IN THE PROCESS OF AUTOMATED CUTTING OF FLEXIBLE SHEET PRODUCTS Inventor: Al Owen Author (Inventor): Al Owen Patent Assignee: WENDON 2000 MANUFACTURING INC. ABSTRACT Apparatus and method are described for use in the process of automated cutting of flexible sheet products and includes a slotted trough positioned in a provided section of an endless belt conveyor, means to fully attenuate and trap the energy of the cutting beam within the slotted trough assembly, means for maintaining upward position of the slotted trough in the provided section of the endless conveyor belt, means to provide vertical and transversal alignment of the cutting beam in relation to an elongated slot provided in the top surface of the slotted trough, means to secure the cutting beam delivery system assembly above the top surface of the sheet product laid on the endless belt conveyor, means to produce a fully synchronized, reciprocal movement of the slotted trough in relation to the speed of the endless belt conveyor and means to cause fully synchronized relative movement of the cutting beam delivery system assembly in X-Y plane with the movement of the slotted trough and the movement of the endless belt conveyor. - 1 - The sheet product is cut in accordance with predetermined geometrical pattern by means of LASER beam, plasma or water jet or other cutting beam. The cutting beam generated in the cutting beam source assembly penetrates the thickness of the sheet product and passes through the slot in the slotted trough where its energy is dissipated without causing upward flashback of the cutting beam, damaging the bottom surface of the sheet product.
