摘要

Improvements introduced in the devices for knotting and resumption of threads in automatic winding machines, especially in automatic cross-winding machines, whose individual winding sites are passed over a knotting device stationary and equipped with a magazine carrying full bobbins on the one hand and a suction arm to take the thread end of the winding coil on the other hand, as well as a wire knotter, characterized by carrying the device a two-phase rope taker that in case of interruption in the winding or in the wire enters each time in the plane of the path of the thread between bobbin and winding coil and which, according to the class of the interruption when an operative phase (resumed) takes the end of the broken thread on the side of the bobbin, coming from a bobbin wound only in part, taking it to a position on top of the knotter and adjoining at the end of the thread drawn from the coil by the suction arm that It operates with adjustable and controllable suctioned air, while the two-phase line taker operates in its other operative phase (knotted) as a command on a program selector which in turn, according to its control, holds or releases the connecting rod of choice. control designed to produce the mechanical control movements operative respectively for the procedure or knotting or resumption.
