摘要

An improved mechanism for winding the yarn in the reel machines that allows the production of biconical reels, essentially characterized by being formed by a rod conveniently bent at one of its ends capable of oscillating on a fixed vertical axis when at its other end. It is already directly driven by means of a suitable coupling by a bar that moves axially in both directions so that the bent end of the rod describes an arc in both directions on a biconical spool or reel on which the thread must be wound.
