Abstract
The present invention refers to a device (1) for gluing the final edge (4a) of a log of band-shaped material (4), comprising a rolling plane (2) for feeding a log (3) that has at least a through opening (7) for the application of a glue (8) on the log (3) itself. The device comprises a blade (9) provided for the application of the glue (8) on the log (3). The application blade (9) is mobile between a first position, in which it is spaced from the opening (7), and a second position, in which it is disposed close to the through opening (7). The device (1) comprises a pressure container (10) for housing the glue (8) to be fed to the blade (9). The container (10) has a slot (12) facing towards, and close to an application edge (9a) of the blade (9) when the latter is in the first position. The slot (12) defines an expulsion direction of the glue (8), transversal to the handling direction (DM) of the blade (9) so that the glue (8) being expelled deposits on the application edge (9a) according to a predefined quantity.
