Abstract
Abstract Apparatus and a method for applying coextensive lines or dots of an adhesive comprising an airless, solenoid-operated, adhesive spray applicator having a plurality of individual applicators within a single housing including a flow distribution arrangement, and a transverse, internally-mounted filter. The filter may be removed and replaced without disturbing the flow lines. Virtually any spray pattern may be applied by staggering rows of applicators and electronically controlling the operation of the individual applicators.

Claim 1
Independent Claim
211 words
Apparatus for dispensing a plurality of coextensive lines or dots of an adhesive comprising: a housing; a plurality of adhesive applicators mounted to said housing, each applicator comprising a solenoid coil, an adhesive dispensing module and means connecting said module to said housing and to said coil for removing and replacing each of said modules as a single unit; an adhesive inlet flow channel within said housing; an adhesive distribution flow channel within said housing connected to said inlet flow channel and to each of said plurality of applicators; and, a filter interposed between said inlet flow channel and said distribution flow channel, said filter comprising a cylindrical fine mesh screen sealingly capped at one end and open at its other end, and means for removing and replacing said filter without disturbing said inlet and distribution flow channels comprising said open end being removably connected to an outlet flow channel within said housing with said filter fitting within an opening in said housing forming an annulus between said filter opening and said cylindrical screen, said annulus being flow connected to said adhesive inlet flow channel, said outlet flow channel being flow connected to said distribution flow channel, and a cap sealingly and removably connected to said filter opening in said housing.
