Flaps, tucks, panels, tabs, walls and analogous parts of paper or cardboard blanks which are to be converted into packets, cartons or otherwise configurated receptacles for smokers' products are bonded to each other by patches, strips or otherwise configurated films or layers of adhesive which is applied to a surface of a first part and is to bond the first part to a second part of a blank. In order to accelerate the setting of adhesive, the movement of one of the first and second parts into engagement with the other of such parts is effected by at least one ultrasonic atomizer for the adhesive. The atomizer can be stationary if the blank is advanced relative to the atomizer by a conveyor and/or vice versa. |
