Abstract: A lathe attachment device is disclosed for producing long articles with complicated profiles. The device contains a beveled multi-teeth cutter driven to rotate in a direction opposite the rotation of a billet to ensure a very short period of contact time between an individual cutting tooth and the article. The cutter is slightly tilted towards the billet in both horizontal and vertical plane. The teeth of the cutter are shaped to each have a pointed end facing the rough part of the billet. Provisions are made to draw the cutter along the billet. The device allows producing a smooth finished long article with complicated surface profile in a single pass with high productivity. Due to limited contact time, it offers extended life of the cutter. The device is used most advantageously to produce long wood articles.

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.
