Abstract: Apparatus for dispensing adhesive onto a strand moving along a strand path includes an adhesive dispenser capable of receiving adhesive from an adhesive supply and having an upper end and a lower end. A nozzle is coupled to the lower end and is in fluid communication with the adhesive dispenser. The nozzle includes an adhesive discharge orifice for discharging the adhesive onto the strand moving along the strand path. A strand guide is mounted at a location proximate the lower end of the adhesive dispenser and upstream of the adhesive discharge orifice along the strand path. The strand guide is configured to receive and guide movement of the strand in spaced relation to the adhesive discharge orifice.

Abstract: Apparatus and methods for applying adhesive to one or more narrow substrates, such as elastic strands, that are in motion. The apparatus includes a coating applicator and an air moving device mounted adjacent to the coating applicator. The coating applicator is capable of applying adhesive in the form of an adhesive filament in a pattern onto each narrow substrate. The air moving device includes one or more air discharge passages capable of directing a flow of air toward the narrow substrate. The flow of air transfers momentum to airborne sections of the adhesive filament for promoting coating uniformity on the narrow substrate.

Abstract: A method of securing an elastic strand to a sheet of material includes moving the elastic strand and the sheet in a converging manner from a position in which the elastic strand is spaced from the sheet to another position in which the elastic strand contacts one surface of the sheet. Discrete elongate segments of adhesive are intermittently applied to the strand. The elongate segments of adhesive secure the strand to the sheet. Various articles of manufacture may be formed using the method, including hygienic articles such as diapers.

Abstract: A guide and method for use in coating of an elongated band with liquid material prior to its attachment to a substrate. The guide supports the band in a tilted orientation relative to a dispensing outlet of a liquid dispenser. The liquid dispenser dispenses a continuous bead or filament of adhesive that wraps around the band to coat the band while it is separate from the substrate. The coated band is thereafter bonded to the substrate.
