Bobbin manipulator for low denier thread for women's stockings - has hollow bobbin with, at one end, centring element for aligning and positioning on spindle

摘要

The bobbins are associated with vertical (22) or horizontal (24) systems to rotate them at 28 000 to 30 000 revolutions/minute. The bobbin includes a central body with an inner axial cavity (26) and ends with flanges (12) defining at the front an annular positioning seating for a count-marker identification element (20). A hand-grip element (16) cooperates with one end of the bobbin, anchored to the inner axial cavity and including gripping and manipulating means (18) outside the bobbin. During the winding, a centering element (14) associated with the other end of the bobbin cooperates with the rotating systems (22,24) to rotate the bobbin. The hand-grip element includes means of axial contact with the count-marker identification element.
