Abstract
A reciprocated knife cuts pattern work material pieces without rotating a housing tube for orientation of the cutting knife. An integrated tangent axis drive motor orients the cutting knife, eliminating any inertia caused by the cutting housing tube and preventing the slowing of the angular acceleration and increasing the speed of the knife orientation. Alternative motor types are provided by various embodiments of the invention.
