Abstract
A tube coupling system for spindles of spinning or twisting machines is provided with two through bore holes arranged at right angles to each other, slightly spaced in an axial direction of a spindle upper part. Two retractable, substantially cylindrical, centrifugal bodies are set in each through bore hole, the centrifugal bodies lying diametrically opposite each other on the outer circumference of the spindle upper part. Directly adjacent of a convex-shaped tube coupling surface, the centrifugal bodies have a conical shoulder arranged on a corresponding opposite surface of the spindle upper part to stop the centrifugal body from falling out. The opposite surface is formed during assembly of the tube coupling system by plastic deformation, whereby the diameter of the though bore holes on the outer circumference of the spindle upper part is reduced somewhat. The advancing of the coupling surfaces against the tube is not hindered during spinning.
