Abstract
An axially movable plunger in a bobbin, and a cam for disposing the plunger in a position resulting in rotation of the bobbin for bobbin winding are formed with engageable planar surfaces, one of which includes a sharp edge hole, and the other of which includes an elongate slot to provide for the cutting of thread between the edges of the hole and slot at the outset of a bobbin winding operation.
