  • Patent number: 4033214
    Abstract: A cutting apparatus for cutting pattern pieces from layups having a low stack height employs a cutting head having a small reciprocating blade suspended from a carriage which moves over the layup. The drive motors for reciprocating the blade and orienting the blade in a particular cutting direction about a .theta.-axis remain in a stationary position on the cutting head as the blade is oriented and elevated in and out of cutting contact with the layup. A blade sharpener is suspended from the head with the cutting blade and is energized by spinning the blade about the .theta.-axis. Drilling is also accomplished by spinning the blade.
