Roller Brushes with Metal Backing Tape

Back in 1931 the history of an inimitable brush began: Kullen-Koti was already the patentee for this spiral brush with a double-sheet backing tape.

Since then we have been developing this brush type and have manufactured the most variations. But one thing always remained the same: the double-sheet backing tape. Because of our experience, this system is the most effective and safe method.

The DBS-Spiral roller brushes types 220 & 221 are extremely flexible in their dimension and depending on the required performance these endless spiral brush coils are mounted on core systems made of mild steel, stainless steel or non-ferrous metal.

Compared with other brush designs we can reach the highest possible fill density with these types and they can be applied with a maximum speed of 55 m/sec without any problems.

Our roller brush coil designed as welded package system will also pack the tiger in your tank! Why is it reasonable and advantageous to purchase a welded package system type 231?

Each face width of a roller brush needed can be divided in a corresponding number of single, compact segments, called packages. What we produce are light and easy-to-handle packages with a constant, high density which facilitates and accelerates the equipping of a brush core or shaft carried out by yourself. The welded package system is not only easy to mount but it also makes you independent of any transportation of the core to the supplier for refilling, packing, delivery times etc. and helps you out of emergency situations.

A further variation of the "Throw-Away" system is type 230. It consists of continuously wound DBS-spiral brushes fitted to a thin walled steel, stainless steel or non-ferrous metal tubular shaft.

According to your requirements the tube could consist of steel, stainless steel or non-ferrous metal. The face width corresponds to the required total brush length (BLG). The complete "Throw-Away" brushes can be simply assembled onto the customer's existing shaft. This method avoids the costly return of the complete shafts when the brushes have to be replaced.

The long period of development of this brush type has left its mark and appears in every detail of the brush. The STS-spiral coil is the only brush type that can be produced with very small diameters.

Already starting at an overall diameter of 17 mm. Offering an enormous choice of dimensions and fill material qualities this brush has almost unlimited applications in light or medium work. The diagram below shows how the STS coil is constructed: the fill material is fixed with a locking wire inside the backing tape.

A very interesting aspect of our STS-spiral coils is the type with inverted fill material that is used, for instance, for polishing, descaling or removal of corrosion off rods or wires in a continuous operation.With an outside diameter of only 20 mm it is possible to reach an inner diameter of zero.

Offering an enormous choice of dimensions and fill material qualities this brush has almost unlimited applications. The pioneering of this brush type has left its mark and shows in every detail of this brush.

The STS-spiral roller brush range contains all measurements from small to extra large and this unbeatable selection of diameters makes this brush a totally reliable tool for light brushing tasks.

Due to the high fill density and precisely ground surface it achieves outstanding results. A flawless radial true runing is a requirement in most cases to achieve the desired brush effect.

The Kullen-Koti roller brush type 350 is one of our "highlights" as it consists of a lightweight aluminium core with horizontal grooves where strip brushes are fitted in.

Two standardized aluminium cores are available:For our brush type 350/54 with 20 horizontal grooves,which means the brush consists of max. 20 strip brushes around the circumference.For our brush type 350/85 with 36 horizontal grooves, which means the brush consists of max. 36 strip brushes around the circumference.

Type 964 is made of single section brushes mounted together on a core up to the required face width. This roller brush type can be mounted on cores made from stainless steel, plastic coated steel or mild steel.

Kullen-Koti recommends especially this type for heavy-duty operations with a high dense brush surface e.g. by using our single section brushes with twisted steelknots (Type Z-SH). But we can manufacture the single section in almost all other fill material types.

Strip roller brushes 302 are indeed unique and easy-to-handle: you only purchase the roller brush core once and easily refill it by yourself with the corresponding strip brushes after wear. And besides, it is a very economical brush system. The roller cores consist of mild steel or stainless steel (1.4301; 1.4541; 1.4571).

The rugged construction allows problem-free operation also in adverse conditions. Roller brushes type 302 are mounted in axial direction around the circumference. The brush cores can be supplied either with journals or with arbor hole for mounting on the existing primary shaft.

Our brushing machine type BM1138 has been constructed previously for heavy-duty conveyor belt cleaning in coal mines and foundries.

Actually we supply it for almost all kinds of industry where conveyor belts have to be cleaned.
