Single band spiral brushes

In the single band spiral brushes - with an internal diameter from 5mm upwards, the bristles are clamped down by a core thread ina U-shaped steel channel. These brushes are available in any length, with various channel widths and a full range of bristle types.

The single band design is suitable for practically every conceivable application. KOTI produces standard channel widths for the single band versions. Width can vary from 2,5 to 12 mm.

Unmistakebly an ALLROUND winner

The spiral configuration of the bristles explains the name given to this type of brush, what the name fails to communicate is the enormous variety of uses to which these brushes can be put. You can rest assured that included in the KOTI range of spiral brushes is a product to suit every application. Spiral brushes can be used wet or dry, can be aggressive or soft, work in temperatures ranging from abnormally high to abnormally low, the list of applications is too long to detail here.

Versatile and longlasting

The high level of bristle density means spiral brushes have a long lifespan. It is also possible to achieve a very smooth brush surface with this type of construction, important for cleaning applications to achieve totally clean surfaces. Bristle density is, of course, depending on the application. Spiral brushes can be supplied with a shaft, constructed as a loose spiral or mounted on a thin wall tube. Spiral brushes can also be made with internal and external facing bristles and can have many types of bristles, anything from nylon or glass fibre to horsehair, brass or crimped steel wire. KOTI produces a range of spiral brushes in two basic designs: single and double band.

Double band cylinder brushes

From a technical point of view the double band spiral brush is a well-conceived tool. This type of spiral brush was developed from experience gained in the manufacture and use of the single band spiral brush. KOTI is one of the manufacturers to initially develop this type of brush and to evolve its design, offering many different sizes, qualities and densities. It is important to use the double band brush where it is technically appropriate, namely where heavy duty and hard bristle are used at high speeds. The double band brush consists of two metal strips, the outer strip holding the inner in place. The number and size of apertures can vary. This type of construction offers the advantage of providing different and accurately measured bristle densities also it is appropriate for a wide range of bristle types, from very fine to heavy duty steel or synthetic fibres. The bristles remain firmly fixed at all times.

The advantage of the double band system in practice is that should the brush be damaged, the tufts are lost only from the site of the damage, whilst the remaining tufts are clamped separately. Spiral brushes are made to the required length with an internal diameter of 20 mm upwards. They can be supplied in various channelwidths and with every type of bristle.

The width of the double band version varies from 4 to 13 mm. It can be fitted with synthetic fibre, vegetable fibre, animal hair or steel wire. In fact KOTI produces as many versions of brushes as there are industrial applications. We always work closely with our customers to produce the appropriate spiral to suit every conceivable application. A suitable solution can always be found by combining the variables available - channel width, channel height, length and density of bristle, and even the shape which the final product must assume.
