Abstract
A flyer-type winding machine includes a forming apparatus which is linearly reciprocated with respect to an axis of a bobbin, coil form or core on which a filament is to be wound while the filament is paid out from a flyer which rotates or orbits thereabout. The forming apparatus guides the filament to the bobbin, coil form or core. Moveable pins are synchronized with orbiting of the flyer to cooperate with the forming apparatus in intermittently catching and releasing the filament so as to control the positions at which portions of each turn of the filament are laid down on the bobbin, coil form or core.
Claims11
A winding machine for winding a filament into a coil comprising:
- flyer means orbiting about an axis of said coil for paying out said filament;
- at least one forming member having a guide surface for guiding said filament from said flyer means to said coil;
- catching means associated with said at least one forming member and being movable in respect to the latter between a retracted position and a projecting position in respect to said guide surface;
- and
- actuating means for said catching means synchronized with the orbiting of said flyer means to dispose said catching means in said projecting position for catching said filament during a first substantial portion of each orbit of said flyer means and to dispose said catching means in said retracted position for releasing said filament to slide along said guide surface during a second substantial portion of each said orbit of said flyer means.
A winding machine for winding wire on a coil comprising:
- a flyer orbiting about an axis of said coil for paying out said wire;
- first and second opposed forming members having sloping surfaces operative to at least partially surround said coil and to guide said wire along said sloping surfaces from said flyer to said coil;
- a first pin in said first forming member;
- a second pin in said second forming member;
- first means for engaging said first pin with said wire during a first portion of an orbit of said flyer and for disengaging said wire at the end of said first portion;
- and
- second means for engaging said second pin with said wire during a second portion of said orbit of said flyer and for disengaging said wire at the end of said second portion.
