Abstract

This computer-controlled cloth cutter uses an endless abrasive-coated wire saw 5 which permits omnidirectional and continuous cutting at high lineal saw speeds with low heat generation. Drawing A shows a cutaway end view taken along line A-A in drawing B. Polyurethane foam layer 2, resting on base plate 3, provides a depressible support table for the layers of material 1. Pulleys 12 and 13, supporting wire saw 5 in a vertical plane, are driven by motors 19 and 20 respectively. V-shaped roller configuration 6 depresses layer 2 to form a trough to allow displacement of motor 20 and pulley 13 beneath material 1 and provide a return path for wire saw 5.

Cloth Cutter

This computer-controlled cloth cutter uses an endless abrasive-coated wire saw 5 which permits omnidirectional and continuous cutting at high lineal saw speeds with low heat generation. Drawing A shows a cutaway end view taken along line A-A in drawing B. Polyurethane foam layer 2, resting on base plate 3, provides a depressible support table for the layers of material 1. Pulleys 12 and 13, supporting wire saw 5 in a vertical plane, are driven by motors 19 and 20 respectively. V-shaped roller configuration 6 depresses layer 2 to form a trough to allow displacement of motor 20 and pulley 13 beneath material 1 and provide a return path for wire saw 5.

In drawing B, motors 14 and 15, controlled by a computer not shown, provide respective X and Y direction cutting movement. The wire saw 5 traverses a path around pulleys 8...13 back to pulley 8. Pulleys 12 and 13, driven by motors 19 and 20 in drawing A, effect a lineal high-speed movement of wire saw 5 around this path in the direction of the arrow. Synchronous rotation of lead screws 16 and 17 by motor 14 results in X-direction movement of pulleys 12 and 13. An air tension cylinder 7 produces a translational force on floating pulley 10, via pulley 18, to continuously provide slack take-up thus causing wire saw 5 to follow pulleys 12 and 13 in the X-direction.

Frame 21, supporting the cutting saw and X-direction movement apparatus, is moved on rails 22, by motor 15, to provide controlled Y-direction move...
