<p>An apparatus (10) and method are provided for cutting a sheet of material (24) into a plurality of segments having curved edges. A sheet of material (24) is placed on a frame (12) having a horizontal support member (20). A clamping device (26, 38) secures the sheet and a first mechanism (56, 58) moves the clamping device and sheet in axial direction. A cutting head assembly (78) is provided with a passively rotatable knife (154, 156) adapted to cut the sheet as the sheet moves in an axial direction past the knife. The cutting head assembly (78) is rotatable about a vertical axis and movable in a lateral direction perpendicular to the axial motion of the sheet. A second mechanism (104, 106) moves the cutting head assembly in said lateral direction, and a third mechanism (130, 132) rotates the cutting head assembly. To produce a continuous cutting line, a controller sends a signal to the first, second, and third moving mechanisms which simultaneously move the corresponding components at a desired rate and distance.</p> |
