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.
