Abstract
A device for automatically feeding bobbins (B) of a wrapping material web (N), particularly bobbins of cigarette paper, to a substantially horizontal mandrel (1) provided with a circle of radially movable jaws (11). The bobbins rest by their lower peripheral surface on a bobbin-carrying cradle (27) which can be stepwise advanced toward the mandrel (1), in the axial direction thereof. The axis of mandrel (1) is eccentric and is upwardly offset with respect to the axis of a bobbin (B) resting on the bobbin-carrying cradle (27) and having the maximum allowable outside diameter within the tolerance limits thereof. At each forward step of the bobbin-carrying cradle (27), the bobbin (B) being each time the leading bobbin is fitted in an eccentric position on the circle of retracted jaws (11) of the mandrel (1). The jaws (11) are then outwardly moved, whereby the bobbin (B) is trued on the mandrel (1) and is lifted from the bobbin-carrying cradle (27).
