VALTORTA - fixed heads

One speed curtain coater available with one or two fixed coating units installed on the basement of the machine.
The heads are available in two executions:
Pressure head: it generates the curtain by pressing the lacquer through two stainless steel blades. The head has been technically studied to obtain an unalterable parallelism of the blades and thus a perfect thickness adjustment of the curtain on the whole width.
Gravity head: simple to use, with no maintenance. This head works by gravity and the quantity of lacquer applied is determined by the opening generated by a steel eccentric roller.
The heavy frame has one speed belt feed system controlled by electronic frequency regulator.
A second speed can be foreseen in case of automated lines.

Advantages:
- high precision curtain coating heads, available in pressure or gravity version, also in stainless steel execution for water-borne lacquers.
- wide choice of machine lengths to be selected according to the workpiece batches to be processed in the line.
- possibility of a double speed control for the conveying system to optimize the control of the batches in line, with control of the loading speed, curtain coating speed and unloading speed.
- pump system, filter and lacquer collection tank studied in a way to avoid the generation of air bubbles in the lacquer.
- stainless steel lacquer tank with double housing , ready for the intallation of a lacquer heating or cooling system.
- stainless steel Cuno filter for continuous filtration of the lacquer flow.
