Abstract:
1. A method of dispensing adhesive comprising conveying a piece of material along a processing path under an adhesive dispenser system having a plurality of stations arranged across the processing path, each station including two glue supply lines for carrying glue components A and B separately, a mixing chamber connected downstream from the two glue supply lines for thoroughly mixing glue components A and B immediately before dispensing, and a deposition device connected downstream from the mixing chamber, each deposition device having a drive mechanism including a motor configured to oscillate the deposition device; separately adding adhesive components A and B within the mixing chamber of each station, to form a rapid gelling adhesive; independently oscillating the deposition device at each station; and dispensing the rapid gelling adhesive through the oscillating deposition device of each station producing a substantially uniform adhesive distribution across the processing path, wherein each deposition device includes a housing device having a bore, and a rotatable cylinder located in the bore of the housing device, the cylinder having an aperture directed toward the processing path, the method further comprising the step of channeling mixed adhesive from the mixing chamber to the aperture in the cylinder, and rotating the cylinder, thereby producing a selected adhesive deposition pattern on the material.
