Definitions

the invention relates to a spray nozzle with a grooved plate, a method for converting slot nozzles and the use of a spray nozzle.
Spray nozzles are also used for the planar application of fluids, in particular adhesives. External mixing nozzles have also proven their worth here.
the fluid normally exits from a nozzle bore.
This bore is surrounded by an annular gap or bores arranged in a ring, from which gas, usually air, flows out at high speed and tears the fluid into droplets or high-viscosity adhesives into threads.
the invention is based on the object of further developing such a spray nozzle. This object is achieved with a spray nozzle according to claim 1, a method according to claim 7 and a use according to claim 8. Advantageous developments are the subject of the subclaims.
the figure 1 shows a grooved plate according to the invention.
This grooved plate (1) now places fluid (2) and gas outlet (3) in a row and any number next to each other.
the grooves are machined into one another and are interlocked so that fluid (4) is fed in from one side of the grooved plate and gas (5) is fed in from the other side.
the outflowing fluid is torn apart in a fan shape by two gas streams on both sides. This creates a line-shaped application as with a slot nozzle only as a non-contact application.
the grooved plate (4) according to the invention shown can also be retrofitted to slotted nozzles with mask plate (1) as a conversion kit in conjunction with an air distribution bar (2).
the air (3) When processing hotmelt, the air (3) must be preheated.
