A mixing device for mixing adhesives containing at least two components comprises a conveying plate having first and second grooved surfaces each overlaid by a respective cover plate. The conveying plate and the opposed cover plates cooperate to define a plurality of separated channels extending through the mixing device. The discharge ends of the channels are interdigitated. First and a second distribution manifolds are defined within the mixing device. A supply port adapted to receive one adhesive component extends through a respective cover plate into fluid communication with one of the distribution manifolds.
