Abstract
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.
