ABSTRACT:
A winder in which the jaws of the mandrel expand automatically by the weight of the reel, without introducing external energy. The winder has a mandrel of horizontal axis (A) whose jaws are expandable by means of links hinged to the end of a sliding pull rod and connected to the frame by a hinged connecting rod. The winder includes a rocker connected to the frame by a fixed pivot axis (D) and to the mandrel by the physical embodiment of the axis of rotation (A), the two axes (D, A) are parallel. The rocker moves the mandrel vertically between a raised loading position and a lowered use position under the weight of a reel and it brings about, simultaneously, sliding of the pull rod, automatic expansion of the jaws, and automatic clamping of the reel.
