System to identify grip position and manipulate bobbins

Abstract

System to identify, grip, position and manipulate bobbins used to wind thin and very thin thread and yarns, such as yarns for women's stockings, the bobbins able to be associated with vertical systems (22) or horizontal systems (24) to make the bobbins rotate, the bobbins achieving speeds of rotation, during the winding step, of 28/30,000 revolutions per minute, the bobbin including a central body (11) with an inner axial cavity (26) and ends with flanges (12), the flanges (12) defining at the front an annular positioning seating (13) for a count-marker identification element (20), the system comprising a hand-grip element (16) axial to the bobbin (10) and cooperating with one end of the bobbin (10) and anchored to the inner axial cavity (26) and including gripping and manipulating means (18) outside the bobbin (10) and, at least during the winding step, the system comprising a centering element (14) associated with the other end of the bobbin (10) and cooperating, during the winding step, with the means (22,24) to make the bobbin (10) rotate, at least the hand-grip element (16) including means of axial contact with the count-marker identification element (20).
