VALTORTA VAL/B

VALTORTA VAL/B

One speed curtain coater available with one or two removeable coating units, the curtain coating units are installed on trolleys and they can easily be extracted to ease cleaning and to shorten lacquer change over time.

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.
- curtain coating units removeable from the machine to ease cleaning operations - 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.
