GLUE APPLYING ASSEMBLY FOR MULTIPLE WEB-FED PAPER HANDLING APPARATUS ABSTRACT OF THE DISCLOSURE A non-pressurized, gravity-fed, pneumatically con- trolled glue applicator assembly is operable to apply at least one uniform stripe of glue to a moving web of material during use thereof. The assembly includes a hollow cylindrical appli- cator head with a glue applying orifice therein connected to an overhead glue supply by means permitting substantially unre- stricted, gravity-induced glue flow to the head. Pneumatically shiftable, apertured sleeve means is carried on the head ex- ternally thereof for precisely controlling glue flow and prevent- ing hardening of the glue when the assembly is not in use. Dur- ing application, a continuously moving web is positioned in lightly touching relationship to the head such that glue is con- tinuously wiped or pulled from the orifice thereof; in this fashion, glue flow is automatically adjusted when web speed is varied to thereby insure uniform application during all modes of operation.
