Abstract
An apparatus for forming and producing elongated threads or filaments of synthetic material such as fluorocarbon resins which can be used to form yarns utilizes, a turning machine having, a chuck assembly for mounting a billet of the fluorocarbon resin material therein, and a lead screw assembly with a tool holder assembly thereon. The lead screw assembly is disposed to move a cutting tool in the tool holder assembly longitudinally and parallel to the axes of rotation of the billet so that a plurality of cutting edges on the end cutting face of the cutting tool can cut simultaneously from the billet a corresponding plurality of sized, shaped and dimensioned threads or filaments which can be combined and formed into the desired yarn. Means are provided to synchronize the movement of the cutting tool with the rotation of the fluorocarbon resin billet. Additionally, the apparatus and method as above described wherein a plurality of spaced cutting tools are disposed for simultaneous engagement of the billet each adapted to cut threads or filaments therefrom.
