Abstract: A cutterhead, particularly for wood lathe tooling includes one or more sleeves each of which has an inner hydraulically operated circumferential gripper for securement to a rotatable arbor, and an outer, independently hydraulically operated circumferential gripper for securement to a cylinder. The outer peripheral surface of the cylinder is provided with longitudinal dovetail ribs. Knife carriers and space-filling limiters slide axially onto these ribs and are locked in place by set screws. Each carrier has a slot for radially receiving a knife to be gripped between a wedge and a corrugated keeper. The keeper and carrier slot are keyed together to provide for radial adjustment of the knife. A threaded pin restrains slot spreading and radially retains the wedge and keeper. Wedge action prevents radial throwing of elements should someone neglect to secure the carriers or limiters, or neglect to elevate the wedges. Knives are slotted for easy removal, and corrugated to match the keepers to facilitate knife height adjustment. All but inner and outer rings of the sleeves, the threaded pins and keepers are made of aluminum. The knives are made of steel.

Abstract translation: 特别是用于木工车床工具的刀头包括一个或多个套筒，每个套筒具有用于固定到可旋转心轴的内部液压操作的周向夹持器，以及用于固定到气缸的外部独立的液压操作的周向夹持器。 圆筒的外周表面设置有纵向燕尾肋。 刀架和空间限制器轴向滑动到这些肋上，并通过固定螺钉锁定在适当位置。 每个载体具有用于径向接收刀具的狭槽，所述刀被夹持在楔形件和瓦楞纸箱之间。 保持器和承载槽键合在一起以提供刀的径向调节。 螺纹销限制槽扩展并径向保持楔形件和保持器。 如果有人忽略固定载体或限制器，或忽略提升楔形物，楔形作用可以防止元素的径向投掷。 刀具开槽易于拆卸，瓦楞纸匹配保持器，便于刀高调整。 除了内圈和外圈之外，所有螺纹销和保持器均由铝制成。 刀由钢制成。
