ABSTRACT:
A spindle assembly capable of accomplishing a swing movement of a spindle bearing mechanism to a machine frame, an operation of holding bobbins on and releasing bobbins from a spindle, and an operation of actuating a rotation stopping mechanism by a sliding movement of an operation handle.
In the spindle assembly according to the present invention, a first support and a second support are secured to a front end of the spindle rotatably supported at the rear end on the spindle cradle. Bobbin holding members are inserted into slits arranged on circumferential portions of the first support and the second support and moved outwardly or inwardly in the radial direction while a rear end of a sliding cylinder attached to an operation handle, which is capable of freely rotating, is inserted into an inside of the first support and engaged with projections of the bobbin holding members. Since the rear end of the sliding cylinder is formed into a conical shape, when the operation handle is drawn out, the bobbin holding members are moved inward in the radial direction, so that the bobbin can be removed from the spindle.
A stop operation of the spindle is performed by engaging a frictional piece moved by rods passing through the first support and the second support by the operation handle with a conical gap of a braking cylinder secured to the spindle cradle.
