During this rocking movement the winding
55 spindle 6 is bodily rocked away from the wind
ing position with the completed cop I5 mounted

Th'e rocking movement of the supporting frame
is limited by the arm I" of the face plate I
hitting the guide rail 5. During the supporting
65 member being thereupon again fed by steps, the
arm I" of the face plate I arrives at the guide
rail 4, so that from there on it enters between
the two guide rails 4 and 5, as indicated in Fig. 6,
and is thus locked against further rocking in
70 either direction in the new position of adjustment.
_ At the beginning of the said
75
turning movement
of the supporting carriage frame the winding
thread 9 is retracted from the respective side of
the thread de?ector I4 by the gyrating cop I5,
