ABSTRACT:
A spindle is driven in continuous manner to wind a ribbon of material upon a core. A traversing guide, moved in a side to side reciprocatory manner by a traversing carriage, guides the ribbon of material so that it is wound in spiral fashion upon the core to form a layer first in one direction and then in the opposite direction one upon the other until a package is formed.
A sensor wheel, attached to the spindle drive shaft for rotation therewith, is provided with a number of fingers the movement of which is sensed by a sensor head to provide digital pulses to a two stage counter. The two stage counter, in turn, controls activation and deactivation of solenoid valves to clutch and de-clutch the traversing carriage to a drive belt and provide the reciprocatory movement for the carriage and ribbon. By providing two stage control a dwell is provided for each direction of reversal for the traversing carriage during which it is not clutched to the timing belt for movement therewith and afterwards it is so clutched but for movement in a direction opposite to its previous direction of movement. By selecting the number of increments of rotation for the spindle during the respective periods of dwell and traverse side edges for the package of stability and appearance can be constructed.
