Abstract
An improved winding apparatus for winding wires and the like, which includes a flyer having a passage for passing the wire through it and driven for rotation around a winding form or winding frame for winding the wire onto the winding form, a roller movably mounted on the flyer for movement in approximately radial direction from a rotational axis of the flyer so as to depress the wire disposed approximately along a direction parallel to rotational axis of the flyer, by a centrifugal force during rotation of the flyer, and biasing members for urging the roller towards the rotational axis of the flyer against the centrifugal force, so that the tension for the wire may be increased during high speed rotation of the flyer.
Claims3
A winding apparatus for winding wires and the like around a winding form, said apparatus comprising:
- a flyer member having a wire passage for passing a wire therethrough onto the winding form, rotatable about a rotational axis, said flyer member including a boss portion;
- and
- means for applying tension to the wire by a centrifugal force during rotation of said flying member, said tension applying means including:
- a slider member slidably supported on said flyer member for sliding movement in a radial direction with respect to said rotational axis,
- a roller member, rotatably mounted on said slider for rotative contact with the wire and for radial movement with said slider,
- a bracket member having radially extending openings therein,
- a pin fixing said bracket member to said slider member for radial movement therewith,
- bolt members fixed at one end to said boss portion, extending through said openings in said bracket member and having head portions opposite said one end, and
- coil springs surrounding said bolts between said bracket member and said head portions so as to urge said roller member through said bracket member and slider member toward said rotational axis against said centrifugal force.
