Device for the elimination of trimmings of rolls or logs of ribbon-like material

An improved device for the elimination of trimmings of rolls or logs of ribbonlike material which can be associated downstream of a shearing machine of at least one roll or log (11), fed by a feeding plane (13) of rolls (10) and head and/or tail rolls (24), consecutively, the device comprising a conveyor group (14) for carrying the rolls (10) and eliminating the head and/or tail rolls (24, 24′), characterized in that said feeding plane (13) comprises rests (15) and said conveyor group (14) comprises flaps (21) both shaped, facing each other and spaced between each other to define central longitudinal openings (16 and 22) for the passage of pushers (17) which allow said at least one roll or log (11) to advance, said conveyor group (14) comprising chains (20) on which said flaps (21) are positioned, and comprising in the same a length of said chains (20) without said flaps (21) defining a movable opening (23) between adjacent chains which allows the passage and falling of said head and/or tail rolls (24).
