Abstract

A winding machine equipped with a traverse mechanism to protect, for example, a reel or wire wound on a reel should feed wire break during feeding of the reel. The mechanism includes a carriage, borne by a support, which moves back and forth along the entire length of a reel and carries a pulley for guiding wire that is wound on the reel. A circular protective channel coaxial with the reel and borne by the carriage moves back and forth with the carriage. The channel includes a circular track portion extending in a plane parallel to and laterally offset with respect to the plane of the pulley, and a deflection portion situated in the same plane as the pulley and limited by a deflection wall.

Claims

1. A winding machine equipped with a traverse mechanism comprising a carriage borne by a support, said carriage being reciprocatingly movable along the entire length of a reel and carrying a pulley for guiding wire being wound on said reel, a circular protective channel coaxial with said reel and borne by said carriage so as to move reciprocatingly with said carriage, said channel including at least one circular track portion extending in a plane parallel to and laterally offset with respect to that of the pulley, and a deflection portion situated in the same plane as the pulley and limited by a deflection wall.

2. A winding machine according to claim 1, wherein said channel comprises a single circular track portion limited by two parallel side walls and an entrance portion situated immediately after the pulley and limited by said deflection wall, said deflection wall extending obliquely and merging with one of said side walls.

3. A winding machine according to claim 2, wherein said single circular track portion and said entrance portion are adjacent to each other.

4. A winding machine according to claim 1, wherein said channel comprises a pair of circular track portions running on both sides of the plane of said pulley, and parallel to said pulley plane, and a center slot between said pair of track portions, said slot being long enough for admitting said pulley, and said deflection wall bounding said center slot at one end thereof, opposite said pulley.

5. A winding machine in accordance with claim 1, wherein said protective channel is formed of two semicircular elements mounted on said carriage and adapted to pivot about axes parallel to that of said reel between a disengaged position in which said reel is free and an engaged position in which the ends of said elements meet.

6. A winding machine in accordance with claim 5, wherein said elements are controlled by jacks, the bodies of which are mounted on said carriage.
