1. A device for taking up the leading end of a strip of material from a new roll, supported with freedom to rotate about its own axis of revolution, and transferring it to a successive work station, comprising first suction means rotatable about an axis parallel to the axis of the roll, by which the roll is set in rotation and by which the leading end of the strip is taken up from the new roll, held and transferred, and second suction means by which the leading end of the strip is received, held and fed toward the successive work station, wherein the first suction means are capable of movement, brought about through the intervention of sensing means designed to detect the passage of the leading end, at least between a first operating position of tangential contact with the roll, in which the roll is set in rotation and the leading end of the strip attracted and held, and a second operating position in which the leading end of the strip is exposed to the action of cutting means and the newly cut end thereupon taken up by the second suction means and directed toward the successive work station.
