Abstract (en)
The object of the invention is a device for automatically feeding bobbins (B) of a web (N) of wrapping material, particularly bobbins of cigarette paper, to a substantially horizontal mandrel (1) provided with circurlarly arranged, radially movable jaws (52). The bobbins (B) are accomodated substantially co-axially to the axis of mandrel (1), in bobbin carrying cradles (C) which are advanced toward the mandrel (1), in the axial direction thereof, by a belt conveyor (T). The bobbin (B) being each time the leading bobbin in the forwardmost bobbin-carrying cradle (C), is clamped exactly in its transfer position on to the mandrel (1) by a positioning abutment formed by the front wall (55, 355) of mandrel (1), which cooperates with the core (A) of a web material bobbin (B), and this bobbin (B) is radially and axially clamped by the jaws (52), the said jaws (52) being provided with axially clamping means (62) which cooperate with a trueing abutment (355) that determines the position, perfectly perpendicular to the axis of rotation of mandrel (1), of the plane in which should lie the bobbin (B) clamped thereonto.
