SUMMARY OF THE INVENTION An object of the present invention is to provide a cylindrical twisting machine which simplifies the structure and eliminates the need for maintenance and management, and which can hold the cradle horizontally when the bobbin is attached and detached.

[0005]

In the tubular twisting machine according to the present invention, an outer end portion of a horizontally movable pintle of a bobbin attaching / detaching device mounted on left and right side plates of a cradle is formed in a tapered shape, and Tapered holes into which the outer ends of both pintles are fitted when the bobbin is detached are provided at symmetrical positions on the left and right inner surfaces of a rotating cylinder having a built-in cradle.

[0006]

In the tubular twisting machine according to the present invention, the outer end of the horizontally movable pintle of the bobbin attaching / detaching device mounted on the left and right side plates of the cradle is formed in a tapered shape, and the cradle is built in. Since there are tapered holes at the symmetrical positions on the left and right inner surfaces of the rotating cylinder that the outer ends of both pintles fit into when the bobbin is disengaged, the left and right pintles must be moved outward in order to disengage the bobbin from the cradle. When moved horizontally, the outer ends of each pintle inevitably fit into the tapered holes on the left and right inner surfaces of the rotating cylinder. At this time, since the outer end of the pintle is tapered, when it is completely fitted in the tapered hole,
The cradle is held exactly horizontal.
