Conventional conveyor belt scra-pers – even those featuring asegment-type design – providea serious disadvantage: They areeither not able to sufficiently adaptto the various degrees of wear acrossthe belt width or they reach thisfunction using mechanical compon-ents that are exposed to extremecontamination by the conveyedmaterial which means they do notoperate with the sufficient operatio-nal reliability.

The innovative, patented TWIST-SWING® technology features uniquegeometry that allows the individualblades to adjust to the belt perfectly.

Unique Thanks to the Patented TWIST-SWING® Feature.The Essential Requirement for Optimum Results andBelt-Saving Operation.

There is no need for any movingmechanical parts in the flow ofscraped material - the special shapeand geometry of the polyurethanefeet alone ensure this flexibility.This in turn ensures that each scra-per blade rests on the belt with theoptimum contact pressure neededto reach optimum cleaning resultson one hand, and keep blade wearto a minimum on the other - therebysaving conveyor belts from prema-ture wear.

For users this means: the bestpossible cleaning results in themost economical way.

Servicing belt scrapers is time-consuming and therefore expensive.Due to the innovative and uniquesnap-in feet the scraper bladesof the STARCLEAN® scraper can bereplaced in no time without anytools and without needing to undoany screw or pin connections.

After blade replacement thetensioning device is reset to thespecified position and all segmentsautomatically adjust to the beltsurface again - THAT'S ALL!

Saving Time and Money: Scraper Maintenance as Quick as a Pit StopThanks to the Toolless Blade Replacement Feature.

Blade Basesfor Heavy Duty Applications

Looking back on several decades ofexperience gained as a supplier andengineering expert for conveyorbelts we know what really counts.

Your conveyor belt is an investmentthat needs to remain operationalfor as long as possible. This meanscleaning must always be gentle onthe conveyor belt without producingsurface wear or increasing existingdamage.

26 27

At the same time, the conveyor beltmust be optimally cleaned to pre-vent premature component wearand to minimise cleaning costs.

There is a system on the marketthat fulfils all of these requirements:STARCLEAN®.

Safe conveyor belt cleaning as awarranty for efficient bulk materialhandling.
