摘要

The bobbin (26) is mounted on a spindle (23) on the base (22). Two guide rods (24) extend up from the base. A swinging lever (25) is pivoted low on the base. Two grooved pulleys (27) are connected to one guide rod, and at least two more (270) are connected to the swinging lever. A leading end of the thread (28) wound onto the bobbin, passes back and forth over both sets of grooved pulleys, in succession. Between the lower end of the bobbin and the base there is a bearing (3).
