Abstract: Apparatus for gluing the final tail (L') of rolls or logs (L) of wound sheet material includes a glue distributor device (10) located below an opening (7) in a roll down table (6). The tail (L') of the roll is separated from the roll (L) by a tail separating unit upstream of the opening (7). The gluing distributor device (10) includes a tank (11) containing glue (12), a rotatable pick up roll (13) located inside of the tank and partially immersed in the glue, and a glue distributor roll (14) positioned externally above the tank (11) and provided with at least one paddle (15). The pick up roll (13) picks up glue as it rotates, and the rotating paddle (15) contacts the pick up roll (13) and picks up glue as the glue distributor roll (14) rotates. The paddle (15) rotates into the opening (7) in the roll down table (6), and glue is transferred from the paddle (15) to a roll as the roll rolls over the opening (7). A cull roll can be culled without applying glue to the roll by mounting a cull roll support projection (19; 21) on the glue distributor roll (14) which is not long enough to contact the pick up roll (13). The cull roll support projection is positioned in the opening (7) in the roll down table (6) when the cull log rolls over the opening (7).
