An apparatus and method are provided for cutting a sheet of material into a plurality of segments having curved edges. A sheet of material is placed on a frame having a horizontal support member. A clamping device secures the sheet and a first mechanism moves the clamping device and sheet in an axial direction. A cutting head assembly is provided with a passively rotatable knife adapted to cut the sheet as the sheet moves in an axial direction past the knife. The cutting head assembly is rotatable about a vertical axis and movable in a lateral direction perpendicular to the axial motion of the sheet. A second mechanism moves the cutting head assembly in said lateral direction, and a third mechanism 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 moves the corresponding components at a desired rate and distance. |
