Abstract
A wire cutting apparatus for use in a winding machine which winds an electric wire or the like round a spool, wherein one terminal wire leading to the coil from the terminal wires formed through the drawing operation of the wire is cleared to remove the entwinement with the cutting arm, the other terminal wire leading to the nozzle of the flyer is descended together with the clamp pawl, with the result that the terminal wire is not involved in the flyer even if the terminal wire is floated after the clamp pawl has released the terminal wire.
Claims6
A wire cutting apparatus for use with a coil winding machine having a flyer movable around a spool and in which the wire extends in a path between the spool and the flyer, said wire cutting apparatus comprising:
- a hook lever rotatably movable in a plane adjacent the level of the wire extending in the path between the spool and the flyer, and having a hook means projecting out of said plane to the level of the wire;
- rotating means on which said hook lever is mounted for intermittently rotating said hook lever for engaging said hook means with the wire and drawing the wire out;
- cutting means actuatable for cutting the wire and disposed adjacent the path of said hook means during rotation and adjacent to which the drawn out wire is positioned at the end of one part of the intermittent rotational movement of said hook lever and at which position said cutting means cuts the wire when the cutting means is actuated;
- and clamping adjacent said cutting means for retaining one end of the wire when the wire is cut by said cutting means.
A wire cutting apparatus for use with a coil winding machine having a flyer movable around a spool and in which the wire extends in a path between the spool and the flyer, said wire cutting apparatus comprising:
- a hook lever rotatably movable in a plane adjacent the level of the wire extending in the path between the spool and the flyer and having a hook means projecting out of said plane to the level of the wire;
- rotating means on which said hook lever is mounted for intermittently rotating said hook lever for engaging said hook means with the wire and drawing the wire out;
- cutting means actuatable for cutting the wire and having cutting edges normally in spaced opposed positions and movable toward each other for cutting a wire therebetween, said cutting edges being positioned adjacent the path of the hook means during rotation and the drawn out wire being drawn between said cutting edges at the end of one part of the intermittent rotational movement of said hook lever;
- actuating means connected to said cutting edges for moving said cutting edges toward each other for performing a cutting operation;
- clamping means adjacent said cutting means and having clamping portions normally in spaced opposed positions and movable toward each other for clamping a wire therebetween, said clamping portions being positioned adjacent the path of the hook means and adjacent said cutting edges and the drawn out wire being drawn between said clamping portions at the end of said one part of the intermittent rotational movement of said hook lever;
- and clamp operating means connected to said clamp portions for moving said clamping portions toward each other for clamping the wire therebetween.
