    • 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.
    • 用于从具有低堆叠高度的叠层切割图案片的切割装置采用具有悬挂在叠层上移动的托架的小往复刀的切割头。 用于使刀片往复运动的驱动马达和沿着θ轴的特定切割方向使刀片定向在切割头上的静止位置,因为刀片被定向并升高与上挡板的切割接触。 刀片磨刀机与切割刀片从头部悬挂,并通过围绕θ轴旋转刀片来通电。 钻削也可以通过旋转刀片来实现。
