SHED WINDING MACHINE ABSTRACT OF THE DISCLOSURE A shed-type coil winier is disclosed in which a sheh form is supported against rotation with in a rotating wire feed envelope. Rotation of the shed form is pre- vented by an eccentric drive. The eccentric drive in- cludes a wire support rotating about a first axis and an eccentric ring rotating about an eccentric axis spaced from and parallel to the first axis. The eccentric ring is driven by a paeallelogram-type linkage so that it rotates with the flyer support in a uniform manner. The eccentric ring engages an eccentric cam on a form support to hold the form support against rotation while the flyer support and the eccentric ring rotate. A window is pro- vided in the eccentric ring through which a wire guile extents with clearance. Consequently, the eccentric drive does not interfere with the rotation of the wire guide system. A jump actuating, system is connected to the form support system to axially move the form in a stepwise manner. The jump actuating system includes a linear actuator located laterally outside of the rotating envelope of the wire guile system and connected to the form support through a bearing plate which rotates about the first axis. The jump actuation system is structured so that a relatively small mass is moved with such step- wise movement, permitting very rapid jumps or axial move ment of the form with a minimum power requirement. All of the rotating elements of the machine rotate with uni- form velocity around their respective centers, so dynamic balance is achieved.
