Abstract:
1. A mixing device for mixing adhesives containing at least two components comprising: a first and a second cover plate; and a conveying plate having first and second surfaces thereon, each surface having a plurality of grooves formed therein, each groove on each surface being separated from an adjacent groove on that surface by a land, the first and the second cover plates respectively overlaying the first and second surfaces on the conveying plate with the lands on each respective surface of the conveying plate being disposed in contact against the cover plate overlying that surface thereby to define separated channels extending through the mixing device, each channel having a discharge end, a first and a second distribution manifold defined within the mixing device, each distribution manifold being respectively disposed in fluid communication with each of a selected plurality of channels, thereby to define first and second sets of channels, the channels being arranged such that the discharge end of at least one of the channels in the first set of channels is next adjacent to the discharge end of at least one of the channels in the second set of channels, a first and a second supply port disposed in fluid communication with a respective one of the first and second distribution manifolds, each supply port being adapted to receive one of the components of the adhesive, and wherein the discharge end of each of the channels is on the exterior of the mixing device whereby the two components form a merged stream beyond the mixing device.
