Abstract

An apparatus for applying fluids such as adhesive, in particular hot melt adhesive, to a substrate movable relative to the apparatus, comprising a main body having a feed passage connectable to a fluid source, an application valve for selectively interrupting or enabling the flow of fluid in the feed passage, and a nozzle arrangement having a distributor passage connectable to the feed passage and at least one nozzle opening communicating with the distributor passage for delivery of the fluid. A body is movable in the distributor passage and has through passages which can be selectively associated with the nozzle opening by means of movement of the body in such a way that fluid is passed out of the distributor passage into the nozzle opening through at least one through passage.
