Abstract
A bobbin changer includes a storage arrangement for storing a number of reels, a reel unwinding station arranged to receive successive reels from the storage arrangement, means for initially rotating each new reel at the unwinding station in a reverse direction (i.e. opposite to the direction of rotation during unwinding), a suction head which is mounted adjacent to the reel and is arranged to pull the leading end portion of the web away from the reel as it approaches the suction head, and means responsive to the movement of the leading end portion of the web and arranged to discontinue the reverse drive on the reel and to initiate a splicing operation.
