Dispensing device having an array of laterally spaced tubes

A dispensing device for dispensing a first and a second component of an adhesive, the dispensing device comprising:

• a first and a second manifold block, the blocks being stacked one atop the other, each manifold block having a distribution chamber therein, the second manifold block having a planar exterior surface thereon, a portion of the exterior planar surface of the second manifold block having a discharge area defined thereon;
• a tube support plate disposed between the first and the second manifold members;
• a set of conveying tubes, each conveying tube having a supply end and a discharge end, the conveying tubes being supported by the tube support plate such that the supply ends of the conveying tubes are disposed in fluid communication with the first distribution chamber, the conveying tubes collectively presenting a predetermined total cross-sectional flow area to the first distribution chamber;
• an array of openings and an array of passages extending through the second manifold block and communicating with the discharge area, the openings receiving the discharge ends of the conveying tubes, each passage being lined by a tubular liner, each liner being disposed in fluid communication with the second distribution chamber, the liners of the passages collectively presenting a predetermined total cross-sectional flow area to the second distribution chamber;
• the total cross-sectional flow area presented to the first distribution chamber by the tubes is substantially equal to the total cross-sectional flow area presented to the second distribution chamber by the passages;
• the openings and the lined passages being laterally spaced with respect to each other over the discharge area such that the discharge ends of the tubes are interspersed among the lined passages whereby first and second components that respectively emanate from the tubes and lined passages are able to intermix with each other on the discharge area of the second manifold block;
• wherein the first and second components of the adhesive are in a predetermined ratio with respect to each other, and wherein the ratio of the total cross-sectional flow area presented to the first distribution chamber by the tubes to the total cross-sectional flow area presented to the second distribution chamber by the passages is substantially equal to the predetermined ratio of the components.

• wherein the total cross-sectional flow area presented to the first distribution chamber by the tubes is different from the total cross-sectional flow area presented to the second distribution chamber by the passages;
• the openings and the passages being laterally spaced with respect to each other over the discharge area such that the discharge ends of the tubes are interspersed among the passages whereby first and second components that respectively emanate from the tubes and passages are able to intermix with each other on the discharge area of the second manifold member;
• wherein the first and second components of the adhesive are in a predetermined ratio with respect to each other, and wherein the ratio of the total cross-sectional flow area presented to the first distribution chamber by the tubes to the total cross-sectional flow area presented to the second distribution chamber by the passages is substantially equal to the predetermined ratio of the components.
