Gluing with Prä machines


Automatic water feeding device

The PräVis is a device for the controlled moisturizing of glue in gluing machines like the PräziCoat.

Glues in open glue trays lose moisture and viscosity due to movement, heat and dry air. To maintain the viscosity of the glue, a continuous and metered water supply is required.
With the PräVis  water may be supplied by two pumps, each to be controlled individually. In addition, the total amount of water to be fed can be regulated independently of the chosen ratio of the pumps.
The settings are retained even after switching off the device. Set profiles may be saved and can be reloaded at any time.
All settings are made on a back-lighted display. The display also indicates the level of the water reservoir or water leaks. Suction and venting of the hoses may also be controlled by the display.
The PräVis is first filled with water. Then the pumps are adjusted.
Each pump is adjustable in 10 levels, setting the switching frequency of each pump. The higher the preset step, the shorter the break between the pumping cycles. On level 10, the pumps are permanently active. The set value may be saved. This setting will be active on the next start of the device.
