<p>The invention concerns an apparatus (10) for applying fluids such as adhesive, in particular hot melt adhesive, to a substrate movable relative to the apparatus, comprising a main body (12) having a feed passage connectable to a fluid source, an application valve (14) for selectively interrupting or enabling the flow of fluid in the feed passage, and a nozzle arrangement (18) having a distributor passage connectable to the feed passage and at least one nozzle opening (34) communicating with the distributor passage for delivery of the fluid. According to the invention there is a body (50) which 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.</p> |
