<p>A gumming method for applying adhesive material (3) to given portions (4) of a support (1), e.g. a paper support, traveling at a given speed in a given direction (F); the method involving the use of applying devices (7, 8), at least one (8) of which is a "spreading" device with a nozzle (10) having an elongated-section output (12a) for the adhesive material (3); the spreading device (8) being mounted with the elongated section of the output (12a) oriented crosswise to the traveling direction (F) of the support (1) and at a relatively small distance from the support (1), and being activated for a relatively short time to coat, on the support (1), an elongated portion (4a) oriented crosswise to the traveling direction (F) of the support (1). <IMAGE></p> |
