Abstract: Apparatus and methods for spraying an adhesive onto a moving surface with a plurality of gun modules which are attached to a transition plate which in turn is secured to adhesive and air service manifolds. The gun modules are secured to movable plates which can be connected to the transition plate in a manner that enables the gun modules to be individually shifted laterally with respect to the transition plate so that the location at which the adhesive is sprayed onto the moving surface is shifted.
