Abstract

PURPOSE: To facilitate detaching and fixing works of a bobbin shaft by using a diameter-expanding plug with a plurality of sliding projections with slant faces for expanding or contracting the diameter of the bobbin shaft easily.
CONSTITUTION: When a main body 20 of a diameter-expanding plug thinned at its top to be extended to the inside of an elestic cylinder 21 is turned to the right by 45°C, slant faces 35 of sliding projections are brought to push divided parts 11 to expand outward, while they contract divided cylinder parts 32 of the elastic cylinder 21 inward and flat faces 36 are brought in contact with the inside of the divided parts 11 to expand them for stopping the plug 20. In this expanded state of the diameter, an unillustrated bobbin tube is strongly pushed from inside by a bobbin shaft main body 1 to be turned in one body. When the plug 20 is turned by 45° after the process of thread-winding, sliding projections 31 are slided on the inside of divided parts 11 for releasing and fitted into gained parts 31. The shaft main body 1 is contracted in its diameter to be detachable fromthe unillustrated bobbin tube.
