Automatic doffing and donning of bobbins on thread winding machines

Abstract

An improved arrangement of thread winders comprising forward facing horizontal cantilevered bobbin winding spindles with automatic bobbin push off means and bobbin supports on rotors arranged for automatic bobbin exchange between the spindles and the supports, one rotor being dedicated to each winder, characterized by, in combination, a hoist for each winder providing an upper and a lower operating position, a rotor for each winder comprising at least two horizontal bobbin supports and rotatable about a vertical axis to align either support with the winder spindle in its lower position for bobbin exchange therewith, and a platform above the rotors providing operator access to the winders in their upper position.
