ABSTRACT:
A cone for dyeing reeled yarns and for equivalent uses, with a truncated-cone wall pervious and having such a thickness so as to create, along a portion of its length, an axial through seat for the centering over the stems of the dyeing equipment and with an axial recess formed by the end part of the truncated-cone wall and an annular bottom, which axial recess is apt to receive the narrowest part of an axially adjacent cone, thereby the cones fitted onto the same stem penetrate partially one into the other.
