Abstract: An automatic cord winder for steel cord braiding machines is disclosed. The winder automatically and continuously drives a spool assembly during a steel cord winding operation. In the spool assembly, a plurality of spools are assembled together into a longitudinal single assembly with a side plate siding each end of the assembly. A spool inlet channel and a spool outlet opening are formed on a winder body. A bobbin lift, movably set in the winder body, is selectively raised upwardly along with the spool assembly from an interior position of the body by a lead screw, thus discharging the spool assembly from the body to a designated position above the top wall of the body through the spool outlet opening. Head and tail stocks, individually having a movable cylinder, are positioned on the top wall of the winder body at positions around the spool outlet opening and selectively rotate the spool assembly while holding the assembly.
