Needle valve application head with reduced bead distance

Oest has developed a variant of its application head PROFITAC FN for 1C-PUR adhesive.

In the case of the use of applicator heads with needle valves, so far only a bead distance of 24 mm could be achieved due to the parallel arrangement of the valves. Now a grid of 18 mm has been realized for a project by mounting several smaller segment heads at an angle to each other. Smaller bead distances are also possible.

Since the adhesive valves of each segment are only switched on one after the other, the dosing pumps accelerate slowly during the start of the adhesive application. This saves the pumps and increases the dosing accuracy during the switch-on.
