Apparatus is disclosed for use in the process of automated cutting of flexible sheet products (12) and includes a slotted trough (10) positioned in a provided section of an endless belt (11) conveyor, means (47, 45, 46) to fully attenuate and trap the energy of the cutting beam (1) within the slotted trough assembly (10), means (20) for maintaining upward position of the slotted trough (10) in the provided section (14, 15) of the endless conveyor belt (11), means (28) to provide vertical and transversal alignment of the cutting beam (1) in relation to an elongated slot (16) provided in the top surface of the slotted trough (10), generator means (23) to secure the cutting beam delivery system assembly above the top surface of the sheet product (12) laid on the endless belt conveyor (11), means (29, 30, 34 - 40F) to produce a fully correlated, reciprocal movement of the slotted trough (10) in relation to the direction of the endless belt conveyor and means (29 - 40F) to cause fully correlated relative movement of the cutting beam delivery system assembly in the plane of the conveyor belt (X-Y) with the movement of the slotted trough and the movement of the endless belt conveyor. The sheet product (12) is cut in accordance with predetermined geometrical pattern by means of LASER beam, plasma or water jet or other cutting beam. The cutting beam (1) generated in the cutting beam source assembly penetrates the thickness of the sheet product and passes through the slot (16) in the slotted trough (10) where its energy is dissipated without causing upward flashback of the cutting beam, which might damage the bottom surface of the sheet product (12). |
