In the top view showing the state, A shows an example of a flangeless bobbin, and B shows an example of a flange bobbin. 1 is the winding shaft of the bobbin, 2 and 3 are flanges, F is an arrow indicating the unwinding direction, 1 is an arrow in the opposite direction of unwinding, X-
Y is the axial direction of the winding shaft 1, D is the diameter (large diameter) of the end surface of the winding shaft 1 on the unwinding side, d is the diameter (small diameter) of the end surface of the winding shaft 1 on the side opposite to the unwinding side, 4 is the bobbin holding base, 5 is the thread layer surface;
6 is yarn, 7a is loop relaxation (occurrence), 7b is loop slippage (transition), and 7c is loop collapse.

Claims

[Scope of utility model registration request]

This bobbin is used by unwinding a wound thread 6 in the axial direction XY, and the diameter of the winding shaft 1 of the bobbin is slightly smaller on the side opposite to the unwinding side than on the unwinding side.
