Abstract
Apparatus for releasably supporting the core of a bobbin of cigarette paper web has a rotary holder which carries a spindle and has a flange extending beyond the spindle to locate one axial end of the core on the spindle. The spindle has apertures for the fingers of a first locating device which is mounted on the holder and engages the internal surface of the core to center the bobbin on the spindle, and for the fingers of a second locating device which is also mounted on the holder and engages one axial end of the core to urge the other axial end of the core against the flange. A ring-shaped actuating element is reciprocable on the holder in the axial direction of the spindle to disengage the fingers of the first locating device prior to disengagement of the fingers of the second locating device or to engage the fingers of the second locating device ahead of the fingers of the first locating device. The fingers are urged against the core by springs which are mounted and dimensioned in such a way that the force with which the fingers of the second locating device engage the core is smaller than the force with which the core is engaged from within by the fingers of the first locating device. This enables the first locating device to center the core while the latter is already biased against the flange. A motor is employed to move the actuating element in a direction to retract the fingers into the spindle and to thus allow for rapid replacement of the bobbin with a fresh bobbin.
