A device for the two-dimensional application of free-flowing adhesive to strip material, especially to furniture edge banding. An adhesive channel is contained in an applicator head and an applicator valve selectively blocks or releases the flow of adhesive in the adhesive channel. A slot nozzle communicates with the adhesive channel, which nozzle has a slot-shaped exit opening for dispensing adhesive onto the strip material. A guide device for guiding the strip material past the exit opening of the slot nozzle along a defined path is removably attached to the applicator head. The guide device includes a first guide element which comes in contact during operation with the surface of the strip material opposite the surface to be glued, and at least one additional guide element which comes in contact during operation with an edge of the strip material.

A method for the application of highly absorbent material onto a moving substrate includes the steps of dispensing a melt adhesive film onto precisely defined areas of the substrate, covering such areas with the absorbent material and then removing excess absorbent material which did not adhere to the adhesive coated areas. The apparatus for practicing this method includes, in one embodiment, an adhesive applicator head operable to dispense the adhesive at timed intervals onto the moving substrate, a measuring head located downstream from the applicator head and timed to release the absorbent material over the adhesive covered areas moving past and a vacuum or mechanical cleaning device for removing excess absorbent material from the substrate. In an alternative embodiment, the measuring head is replaced with a receptacle containing absorbent material within which the substrate is immersed for coating the adhesive covered areas. The method and apparatus are particularly adapted for use with conventional machines in the manufacture of hygenic articles such as sanitary pads, tampons, diapers and the like.
