<p>The invention relates to a wrapping mechanisms for cables, ropes or strands on reels or coils without holder. The mechanism comprises a non-synchronous motor (1) connected to a non-syschronous coupling (2), the speed of which is reduced by a planetary reducer (3) which alternatively transmits the rotation motion by means of a jaw clutch (4) to some gear wheels (5) on the shafts of which there are fitted some reels (6) and by means of some gear drives (7) fitted behind a non-synchronous coupling (8) and then, by means of some gear drives the rotation motion is transmitted to a bidirectional coupling (9) rotating one way or another a flat-threaded screw (10), imparting a straight reciprocating motion to a thread distributor (12), the change of the sense of motion being controlled by some arresters (11).</p> |
