Abstract
In a system for the simultaneous perfect winding of a plurality of wires, during steady state winding the load angles of each of the wire guide tubes is periodically sampled and the spindle speeds are individually adjusted so as to maintain the load angle at a predetermined value. During non-steady state winding at the end of each layer, the spindle speed is maintained constant and the traverse speed is increased so as to reduce the load angle to zero, after which the traverse direction is reversed. Two pistons in the tailstock reinforce the bobbin in both the radial and axial directions.
Claims17
A system for simultaneously winding elongated filaments in at least one layer of turns on rotating spindles, comprising:
- means for supporting a plural number of rotational spindles upon which spools may be mounted;
- variable speed motors for separately driving each of said spindles;
- a traverse movable along a traversing path substantially parallel to a axes of said spindles;
- at least two filament guides mounted on said traverse for guiding filaments to be wound on said spindles;
- means for separately detecting a position of each of said guides relative to said spindles along said traversing path;
- and
- control means responsive to said detecting means for independently controlling the rotational speed of each of said variable speed motors, whereby said filaments are wound in a desired pattern.
A rotating spindle and tailstock assembly for winding a filament, comprising:
- a spindle rotatable about a longitudinal axis thereof, said spindle having an axial bore extending from one end and tapering so as to have a progressively reduced diameter with increased distance from said one end;
- a first supporting flange formed on said spindle adjacent said one end thereof;
- a cylinder movable coaxially with said bore;
- a first piston fitted in said cylinder and having a head extending from said cylinder and including a second support flange positionable at an end of said spindle by movement of said cylinder towards said spindle;
- a second piston fitted in said first piston and having a head extending from said first piston, said head having a taper corresponding to the taper of said bore, said head matingly fitable in said bore by movement of said cylinder towards said spindle,
- fluid means in said cylinder for advancing said first and second pistons in a direction further towards said spindle;
- whereby a filament being wound on said spindle between said first and second flanges is axially rigidly supported by said flanges and radially supported by said head of said second piston.
