Abstract: The flyer mechanism includes a readily adjustable wire tensioning mechanism which is repeatably settable so that varying degrees of tension may be applied to the wire along the flyer arm. Centrifugal action is used to transfer wire flutter from a region near the coil form to a fluttering loop of wire between the tensioning mechanism and the flyer nozzle. The tensioning means are usable singly or in combination with a wire guide to control the size of the centrifugally generated loop. The flyer discharge nozzle may, in effect, be "free floating" and the attitude of each nozzle is controlled by the strand of wire extending between the form means and such nozzle. With this arrangement, the previously mentioned fluttering loop can have a maximum affect on the tension of the wire extending between the form means and nozzle. All of the features disclosed are operable for either direction of flyer rotation.

Abstract: Apparatus for stripping insulation off wire in a stator coil winding machine. A frame supports a blade assembly including circularly spaced blades that encircles moving wire in the machine. The blades are individually pivotally mounted so they can rock against the wire. The array of blades rotates about an axis coaxial with the wire and cuts insulation off the wire as it moves therethrough. The blades rock due to a thrust block that rotates in synchronism with the blades, and moves axially against the blades. A thrust block cam surface engages cam surfaces on the blades and thus pivots them against the wire. Depth of penetration of the blades is controlled very accurately by a cam follower engaging a cam surface on an adjustably positioned wheel. During stripping, the wire stops, and a pulley arrangement forms an open wire loop downstream of the blades by pulling wire transversely from the normal wire travel path.

Abstract: A method and apparatus for protecting the slot liner cuffs during insertion of prewound coils in the manufacture of stators for electric motors and other dynamoelectric apparatus. In order to protect the slot liner cuffs, which protrude beyond the face of the magnetic core, a plurality of movable fingers are positioned between the cuffs of those stator slots which have the greatest slot fill. As the windings are pulled into the appropriate slots of the magnetic core, they ride over and are at least partially supported by the highly polished surfaces of the fingers, which are in close proximity to the liner cuffs and extend slightly beyond the ends of the cuffs. This prevents the full force of the coil from being exerted against the cuffs as the coil is pulled into the slots, thereby avoiding damage to the cuffs which may otherwise result in exposing the wires of the coil to the sharp edges of the stator core.

Abstract: A wire vibration damping device for use in coil winding machines of the wind and shed type. The device comprises a guide rail which partially or completely encircles the coil form and is connected to the structure which supports the coil form by means of a plurality of downwardly depending guide posts. The guide rail is supported from above the winding plane and includes a downwardly facing lower edge which is located slightly above the winding plane yet sufficiently close to it that it deflects excursions of the wire above the winding plane as it is fed from the flyer thereby damping oscillations of the wire which would otherwise cause improper shedding off the coil form. The support posts for the guide rail are clamped within a bracket mounted to the lower portion of the support structure for the coil form and are vertically adjustable relative thereto so that the position of the guide rail can be fine tuned to ensure optimum damping of the wire oscillations.
