Device for taking up the leading end of a new roll of strip material and transferring it to a successive work station
First Claim
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.

Abstract
With the new roll of strip material supported in readiness and free to rotate about its own axis, the leading end of the strip is taken up and traversed in the direction of a successive work station by an aspirating roller, rotatable about an axis parallel to the axis of the roll, designed to attract and hold the strip before releasing it onto an aspirating conveyor belt by which the transfer to the work station is completed; the roller is capable of movement, piloted by a sensor positioned 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 strip is cut by a blade and the trimmed end then taken up by the aspirating belt and directed toward the successive work station.
