(54) Device for joining the web from an exhausted spool to the initial end of a new spool.


(57) The device comprises a station (50) in which web is normally in transit in one direction only and in which the initial end of web from a new spool (A) is adapted to be positioned in the same direction and aligned transversely to the station (50). Sensors (43, 44) detect when a spool (B) is nearly exhausted, and locking members (57, 59, 64, 66 - 69) are disposed downstream of the station (50) and controlled by the sensors (43, 44) so as to stop the tail end of the web in transit in the station (50), a cutting device (48) cuts the tail end of the transverse alignment, thus determining the terminal end of the exhausted web. The device also comprises a selector (25) for removing the cut tail end for the terminal end, and a gripping device (110, 111a, 114, 115) for transferring and sticking an adhesive strip and movable from the transverse alignment zone to a position remote therefrom and adapted to hold the strip in the remote position and stick it in the alignment position to the initial and terminal ends placed in abutment.
