Abstract: A device for detacking leaf material (T), such as tobacco leaf, from bobbin (B), provided with a frame (1), a table (2) with co-acting detacking member connected to the frame, a winding-off reel (3) for the filled belt-shaped carrier, a winding-up reel (20) for the emptied belt-shaped carrier connected to the frame and guide rollers (17, 18, 19) such that the belt is guided stretched over the table, wherein a straight guide edge (8) is placed at a short distance to the front edge (26) of the table in order to form a gap-like space, the winding-off reel is held in or close to a plane which extends perpendicularly of the table and through the guide edge, and one of the guide rollers (17) is arranged on the side of the guide edge remote from the winding-off reel, so that the belt is bent sharply, the tobacco leaf is drawn loose of the belt part and still deposited on the same side of the belt part, whereby any adhesion that may occur is eliminated.
