- simple and quick installation
- little weight
- low maintenance
- very effective
- Execution in PU and with hard metal
Our new pressure system / mounting system does not take up any space.
It is located inside the support tube.
Our new system is already in use for:

The scraper consists of a special polyurethane (FDA-approval) developed by us, with very good sliding properties and wear resistance. Polyurethane offers a very dynamic capacitance and good
resilience. Product contaminations, even from mechanical damage (i.e. by foreign bodies), are nearly impossible due to its fold and tear resistance.
Longevity is secured by a good to very good resistance to weathering and to UV radiation.
In order to generate the required pressure from the scraper to the belt, we use a maintenance-free torsion element, which is located in the axle tube. This kind of positioning is space saving as well as giving security for the torsion element against attacks from outside. For the sealing between torsion element and axle tube, two o-rings are used. These guarantee an optimal protection against the infiltration of dirt or product remains.
The easy construction of the scraper is the basis for a cost-effective assembly. In most cases there will be no changes on the conveyor belt or on the hopper, for instance. This is dependant on the on-site construction. If the scraper needs to be reallocated after an “on-site assembly”, this can be carried out easily by twisting the eccentric counter bearing.
In order to set the scraping pressure from the scraper to the belt, the two fastening screws need to be loosened and the torsion element can be adjusted adequately.
To clean the scraper, you can flap it from the belt surface contrary to the direction of torsion with the hand lever without additional tools.
Generally, our scrapers are for all-purpose use. Mainly they are used as head or drum scrapers though. This position is effective and easy to install.
The positioning of the scraper is dependent on the transported product and its further use.
If the scraped product shall remain within the production flow and be further transported, the scraper position needs to be similar to mounting position 1 (see picture).
If the scraped product shall be separated from the main stream, the scraper position needs to be similar to mounting positions 2 or 3.
The hinge moment, which emanates from a supporting tube located behind the scraper, is being transmitted to the scraper via corresponding levers. The hinge moment can be set individually, like for the standardized scraper.
Besides our standardized scraper (which is mainly used as head or pulley scraper), we offer our customers the universal scraper, which is suitable even for scraping difficult products like sugar
icing for instance.
The universal scraper is manufactured with a supporting axis, instead of a supporting tube.
Even though our scrapers have been developed for the food industry, they are now being used in a wide scope of applications including the non-food industries
The outcome of our development and its present success is a confirmation for us that innovative products can be applied successfully in a wide field, even though they have been engineered for a certain application.
