This supply unit for nozzle assembly is designed and installed especially for the continuous manufacturing of aqueous solution and the dosing of this watery solution to two rotation- nozzles-systems on the converting machine.

The supply unit for nozzle assembly consists of the dosing unit, the backflow conveying unit and the control cabinet wit control system.

Dosing unit:

- Storage hopper for liquid products (additive) and mixtures (aqueous solution)

- Water dosing (flow control valve, flowmeter)

- Additive dosing (diaphragm metering pump)

- Dosing of the watery solution (gear metering pump; flowmeter)

- Plate heat exchanger for cooling backflow

Backflow conveying unit:

- Collecting hopper with solid-separation

- Measuring backflow (flowmeter)

- Conveying backflow / watery solution (gear metering pump)
