Method for applying adhesive to a paper web in the tobacco industry and cigarette filter rod obtained by this method.

摘要

Two projection devices (10 and 11) each form a strip bonded to the web (1). The marginal strip (7) forming the seam is projected under the action of pressure of compressed air which is preheated at (20) and passes through into the tube (19), while the inner bonded strip (6) is formed by the device (11), fed with cold compressed air via the duct (21). The adhesive contained in the receptacle (8) is placed under pressure by the duct (12) and reaches the projection device via the pipe (9). <IMAGE>
