Abstract

The drum (5) is at the station of wrapping and extraction of a coil of material wound on the segments (16) and bounded by the radial arms (24 and 21). Once the wrapping film has been placed about the coil of material and the arms (24 and 21), the cross-piece (17) is advanced so that the arms (21) are overturned backward and can be extracted from the front inner edge of the wrapping. Next, the pushers (28) move the wrapped coil of material by pressing against the rear flank of the wrapping between the arms (24). The latter pivot towards the front against the bias of the springs (26) so that their outer ends also pass under the inside edge of the rear flank of the wrapping. When the jack (19) returns the cross-piece (17) to its starting position, the arms (21) are righted by the action of the ramps (23). This device permits choosing the inside diameter of the coils of material at will, without being hindered by the presence of the radial arms (21).
