    Abstract: A positive drive strand-handling mechanism for advancing one or more strands of yarn about a feed roll. The mechanism has provision for stopping the feed roll by disengaging a train of gears in the event of strand breakage, and for absorbing shock when the gears are engaged to again advance the strand. The shock-absorbing means is a gear on a common shaft with the feed roll, the gear having slots substantially encircling the shaft with means including resilient elements in the slots for absorbing shock and drivingly connecting the gear and the shaft.

    Abstract: A bobbin holder for magnetically holding bobbins in an operative position on a winding machine. A dish-shaped seat of the holder has a magnet which magnetically couples a magnetic end ring of the bobbin core to the seat. The bobbin core is ejected from the seat by tipping a bobbin receiving tube upon movement of the seat from an active or unwinding position toward a reserve position to receive a fresh bobbin. Air passages through the seat communicate with a hollow of the core and facilitate pneumatic end retrieval of the yarn.
