Abstract
A free, rotating flyer is suspended from an arm hinged to the threadboard of a frame. The flyer is detachably connected to a flange which is positively driven by a timing belt. The flange coaxially surrounds the spindle.
Claims29
In a machine to twist material having
- a. a frame,
- b. delivery rolls on the frame,
- c. a spindle mounted for rotation about its axis,
- d. a bobbin on the spindle,
- a flyer having legs mounted for rotation coaxially with the spindle,
- f. carriage means interconnecting the flyer and spindle through the frame for causing relative axial movement between the flyer and spindle, and
- g. said flyer being means for conducting the material from the delivery rolls to the bobbin,
- h. THE IMPROVED METHOD OF OPERATION COMPRISING THE STEPS OF:
- j. preventing deflection of the legs of the flyer by
- k. connecting them to a flange surrounding the bobbin,
- m. journaling the flange to the frame by a base plate,
- n. rotatably driving the flange, and thus
- o. rotating the flyer.
