ABSTRACT:
A method of forming a gummed band on a web of paper (1) is provided. A marginal band (7) forming a seam is projected by one (10) of two devices (10, 11) under the action of compressed-air pressure, the air being pre-heated (20) and passing into a feed line (19), whereas an inside gummed band (6) is formed by the other device (11) fed with cold compressed air through a duct (21). An adhesive is contained in a reservoir (8), kept under pressure by means of a tube (12), and reaches the projection device through another duct (9).
