Where pasty or highly viscous, no longer self-leveling components are required, they are processed with follower plate systems. As there are different cylindrical containers available from the material manufacturers, the follower plates are selected according to the container size. The material is received directly from the containers. The most common containers are 20 l hobbocks, 50 l and 200 l steel drums.
The configuration of a NODOPOX usually consists of a mobile basic model, which is supplemented by modules from the existing module system. The systems can be designed as 1C, 2C systems or for more components. The mixing ratio is defined via the integrated Siemens control in the operating panel. The required program modules are individually compiled in the PLC by our programmers and adapted to the application process. Pot life, shot quantity and, in the case of volume flow-controlled systems, also the mixing ratio, for example, can be set via the machine control on the touch screen.
In order to avoid process interruptions during drum change, we developed buffer containers in 2009 which are automatically filled by refill stations and thus ensure uninterrupted dosing.
The systems can also be equipped with various vacuum options – patented by TARTLER – which can improve or even guarantee process reliability.

Module elements
A dosing system of the NODOPOX series can be equipped with the following modules. As a manufacturer of special machines we adapt all machines to the respective process conditions.
Vacuum drum (TAVA)
Material degassing & recycling
Air and humidity in the material reduce the material quality as well as the process stability. If the material is freed from this disturbing air before processing with a TAVA F, you create the best conditions for the actual application.
In addition to material optimization, the TAVA F module can also be used to reduce material costs and significantly improve the eco-balance of processing operations. Since unmixed material residues from opened drums, from trial runs, or from the setup phase no longer have to be rejected and disposed of thanks to the degassing station, but can be reused.
- Filling without any air pockets
- Improved storage stability
- Maximum occupational safety
- Guaranteed process reliability for subsequent applications
- Cost reduction through material preparation

Melting unit
In order to be able to process non-flowable material at room temperature, it is often necessary to heat the tank and hoses. In order to protect sensitive material, a melting unit of the follower plate can melt / liquefy exactly as much material as is actually processed. The remaining material in the drum is not unnecessarily affected, as would happen if the tank were completely heated. In addition, time is saved because production can be started faster.
In order for the system to function, all other components, such as hoses and mixing head, must be equipped with a heater to prevent cold spots and thus guarantee optimum mixing of the components.
This melting unit is interesting for applications such as
- hot-cast adhesive
- hotmelt

Vacuum drum change
Zwischen Materialoberfläche und Folgeplatte wird ein Vakuum hergestellt. Die Folgeplatte wird erst nach Erreichen des definierten Vakuums – unter Einhaltung des Vakuums – kontrolliert abgesenkt. Somit die absolute Sicherheit, dass KEINE Luft in den Prozess gelangt!
Dieses System sorgt für einen absolut prozesssicheren Fasswechsel bei Folgeplattenanlagen für hochviskose Komponenten. Zusätzlich erreichen wir eine Steigerung der Arbeitssicherheit, es gibt weder Materialverlust noch besteht Spritzgefahr.

vacuum-assisted follower plate
Vacuum-assisted follower plate deaeration
Vacuum-assisted follower plate deaeration not only increases process and work safety but also reduces material loss.
The follower plate is lowered by extracting the air between the material surface and the follower plate until it sits tightly on the material. This drum change procedure is operator-friendly, prevents dangerous splashing and minimizes material loss, as no material has to be extracted via ball valve or similar outlet.
The machine operator can be sure that there is no harmful air, which would hinder the pumping process, between the follower plate and the material surface. The air is extracted at the push of a button. No manual intervention is required.

Cold spot heating
Heating
All machine parts, from the container to the hose and mixing head, can be heated to reduce the viscosity of the material – for example, to shorten the pot life or improve mixing of the components. Depending on the application, there are several options available.
Container
- Jacket heating (adapted to the container)
- Double jacket (heating with water or oil)
- Extra agitators for a better heat distribution
Hoses
- Heated hoses
- Insulation
Depending on the sensitivity of the material, all possible cold spots must be additionally heated or insulated. Heating cartridges, ring heaters and heating tarpaulins are used in this process.

Mobility
It may be necessary for a plant to be mobile, depending on its size and location/purpose. There are several ways to achieve mobility:
- Mobile frame
- Own drive unit
- Trailer coupling

Volume Flow Control
Machines with a volume flow control system continuously measure the flow rate of the material and report any deviations to the pumps, which automatically adjust the flow rate accordingly. This happens within seconds and guarantees a constant flow rate and mixing ratio.

Refilling from IBC tanks (free flow)
Refill station
Coupling for connecting a movable refill station
Refilling using vacuum
Refill
To keep the dosing process running longer, we offer refills from IBCs or drums. There are different solutions for the realization of a refill.
Automatic Refill
- 1st option: Dosing containers are connected to a mobile refilling station (modern connection with couplings without loss of material)
- 2nd option: Dosing containers are connected directly on the base frame with e.g. an IBC
- 3rd option: Refill containers are also located on the base frame
The process is controlled via automatic refilling e.g. when a minimum sensor level is reached.
Vacuum Refill
If the material must not come into contact with air, we offer dosing containers in vacuum atmosphere. When refilling, the negative pressure is used to “pull” the material out of the refill containers.
Free Refill
The free refill, also called “free-flow”, uses gravimetry. The material flows from the higher positioned refill container into the dosing containers. No pump is required.
