<p>Coil winding machine for the winding of coils without support, of bare or insulated wire, comprising a main drive shaft, onto which is keyed a set of control cams controlling the movements of: a spindle, on which the coil is formed and which is caused to rotate by a gearing comprising a sector gear, oscillated by a first cam, and a pinion gear keyed onto the spindle shaft, the pinion and the shaft being movable parallely to themselves along an arc concentric to the rotation axis of an intermediate gearwheel; a wireguide, for feeding the wire and guiding the distribution of the turns, the forward movement of which is controlled by a second cam and which comprises structures for positively retaining the wire during its forward movement at the start of the winding; shears for cutting the wire at the end of the winding, which are controlled by a third cam and which can be adjusted with precision in respect of the spindle and the wireguide, so as to determine the length of the terminals at the start and at the end of the winding; and means for determining the turns distribution law, which acts on the wireguide.</p> |
