A circular crown shaped pressure disk (1), furnished with, on its external rim, jutting stirrup shaped, flexible elements (2) whose size makes them press on the internal surface of the drum (7) within which the disk is housed. The internal rim of the disk is equipped with winglets (3) and with flexible tabs (5) directed nearly tangentially in respect to the tubular trunk (8), placed at the center of the drum (7). The flexible tabs are for stopping the rise of the bundle of coils so as to impede their knotting and to help guiding the wire, as it is pulled to the outside of the drum and unwound from the bundle.

a circular crown 1 having on its outer edge distributed stirrup a thickness extending between a top surface and a bottom surface of the crown. The crown extends between an inner edge and an outer edge and, based on the thickness of the crown, the crown is non-flexible. Stirrup shaped flexible elements 2, with a dimension that allows can be equally distributed about the outer edge of the crown and are thinner than the crown thickness to allow their adherence—bending inwards if necessary—to the internal surface of the drum 7 in which the invention is positioned. In this way it can stop the Further, the stirrups can be U-Shaped. By utilizing flexible stirrups 2, external parts of the coils can be prevented from rising along the internal surface of the drum 7 and to go over rising above the level of the pressure disk itself and as a consequence of. If the wire is allowed to spring up between the device and the wall of the container, the pulling action, of the wire could move the springing wire close to the tubular trunk 8 and create a knot on the disk 1 with the effect of stopping its normal flow.
On its inner edge the disk 1 is equipped with distributed guiding winglets 3 and flexible tabs 5. The former having the Flexible tabs 5 can be generally rectangular and extend at a non-perpendicular angle from the inner edge. The flexible tabs also have a front edge facing the wire during the unwinding and an opposite rear edge. The front edge is at an angle less than 90 degrees from the inner edge of disk 1 wherein the wire travels along the front edge during the unwinding of the wire from the coil. Winglets 3 have a side profile 4 of the side oriented towards the axis of the drum 7, connected to the thin skeleton 6 curved into a spiral towards the center of the same drum, so that the wire of the bundle, when pulled, is evenly sustained and guided towards the center of the drum 7 to emerge from it staying adherent to the tubular trunk 8 against which it is pushed by the sequence of flexible tabs 5 that follow it as it unwinds.
The invention therefore carries out two actions, the first one consisting in a braking action that also regulates the movement of the coils at the top of the bundle, in fact said movement would be turbulent and disorganized without it. The second action is that of convoying the wire that unwinds making it emerge from the drum 7 in an almost axial direction as well as a rotatory one to follow the coils that unwind from the bundle.
