cone for dyeing of yarn in the rock with the guidance of the stalk and the axial groove for the interpenetration of overlapping cones

摘要

A cone for dyeing reeled yarns and for equivalent uses, with a truncated-cone wall (2) pervious and having such a thickness so that to create, along a portion of its length, an axial through seat (2) for the centering over the stems of the dyeing equipment and with an axial recess (14) formed by the end part (13) of the truncated-cone wall and an annular bottom (11), which axial recess (14) is apt to receive the narrowest part (1A) of an axially adjacent cone, thereby the cones fitted onto the same stem penetrate partially one into the other.
