Abstract
In apparatus for winding a filament (12) onto a bobbin (16), a free arm follower (32, 64) with guide pulleys (46, 48, 76, 78) is provided for both the bobbin (16) and filament supply spool (14). The free arm followers swing in respective arcs parallel to the longitudinal axes of the supply spool (14) and bobbin (16) to produce consistent and uniform filament winding. A quadrature sensor (90) determines the number of actual windings laid down in each layer which are compared (94) with predetermined winding number and if the numbers do not coincide, a stop for flaw circuit (102) stops the spindle motors (28, 82) to enable winding flaw correction. A layer counter (104) energizes a lead angle driver (106) to provide correct winding lead on changing winding direction with each new layer.
