ABSTRACT:
Apparatus for the formation of packages of elongated flexible material wound upon a pirn supported and rotated in the apparatus, the apparatus having an operating carriage mounted for reciprocation parallel to the axis of the pirn, mechanism for reciprocating the operating carriage with a basic reciprocating movement lengthwise of the pirn, a vibrator mounted upon the operating carriage, a thread guide vibrated by the vibrator in a direction lengthwise of the pirn with an amplitude which is a fraction of the amplitude of reciprocation of the operating carriage, and a controlling mechanism for insuring the periodic translational shifting of the thread guide to the top of the pirn. The operating carriage is mounted upon guideways fixed to the body of the apparatus and extending parallel to the axis of the pirn, a driving belt for the carriage having spaced parallel runs thereof extending parallel to the carriage, the carriage being selectively clamped to one or the other of the rectilinear runs of the driving belt so as to drive the carriage in the direction of the run of the belt thus gripped. The controlling mechanism comprises a controlling belt stretched between rollers at the opposite ends of the body of the apparatus, the controlling belt bearing switching dogs for controlling the mechanism which selectively clamps the carriage to one or the other of the rectilinear runs of the driving belt.
