Abstract (en)
[origin: EP1065304A1] Yarn tubes are held on a textile machine spindle by a clutch comprising a body (1) attached to the spindle, a pressure sleeve (3) sliding on the spindle in a bearing (4), and an end piece (2). Two sets of components, e.g. balls (5,6), move radially in recesses with tapers (7,8) to give a centralizing action and grip the tube. As the yarn tube is placed over the coupling, balls (6) are pressed against a taper (7) and move the sleeve (3) axially upwards and at the same time centralize the tube. When the spindle begins to rotate, balls (5) are pressed against the taper (8) by centrifugal force and push the sleeve (3) downwards so that the balls (6) are forced against the tube wall and grip it.
