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.

Abstract: A device (30) for handling a load (C) such as a sheet iron coil comprises a holder (32) capable of carrying the load (C). The holder (32) is able to be rotated on a frame (31) between a first position, in which the axis of the load (C) is vertical, and a second position, in which the axis of the load (C) is horizontal. The frame (31) of the device (30) is coupled to a driving assembly (35) so as to be mobile in order to load and unload the load (C) on a reel (D). The holder (32) includes a mechanism for maintaining and positioning (36) the load (C), retaining the load (C) during a change of the position of the load, and depositing the load on and/or removing the load from the reel (D).
