Abstract
In a spray gumming unit, a gumming device is equipped with an ejector that sprays an adhesive substance and that is connected with a shutter element. The shutter element moves towards and away from the ejector between a position where it closes the ejector and in which a pad, fixed to one end of it, is in contact with the ejector, and a position where the ejector is left open. During the movement of the shutter element and of the pad between the ejector open and closed positions, an applicator applies an antiadhesive liquid substance on the pad.
