ABSTRACT:
Apparatus is provided for applying glue or a similar adhesive onto a substrate such as a paper web. It comprises a nozzle plate (20) with exit openings (29) with a small diameter, which are arranged in at least two rows (32,33), staggered closely behind one another in the transport direction (4). The rows are also transversely offset with respect to each other such that the outlet openings of one row (33) are aligned with the spaces (37) defined between the outlet openings of another row (32). In this manner, side edge portions (47) of the adhesive issued from the outlet openings of the one row (33) contact and merge with the side edge portions (47) of the adhesive issued from the outlet openings of the other row (32) whereby a continuum of adhesive is produced.
