Can be fixed at any angle desired.
Channel type depends on the application.
Density, thickness and length of bristle as required.
Applications include cleaning, sealing, and guiding.
Brush strips are available in single and double band versions.
This product type also includes versions with a winged channel and miniature strips that can be used for sealing gaps.
The product range also includes brush strips for use as seals against draughts, damp and dust.
In addition to the standard products, there is also a very varied range of special applications.
In single band spiral brushes with an internal diameter of 5 mm upwards, the bristles are clamped down by a core thread in a U-shaped steel channel. These brushes are available in any length, with various channel widths and a full range of bristle materials. The single band design is suitable for practically every conceivable application.
Spiral brushes can be used wet or dry, can be aggressive or soft, work in temperatures ranging from abnormally high to abnormally low.
VERSATILE AND LONG-LASTING
The high level of bristle density means spiral brushes have a long lifespan. It is also possible to achieve a very smooth surface with this type of construction, important for cleaning applications to achieve totally clean surfaces.
Bristle density is, of course, dependent upon the application. Spiral brushes can be supplied with a shaft, constructed as a loose spiral or mounted on a thin walled tube. Spiral brushes can also be made with internal or external facing bristles, and can incorporate many types of bristle material, anything from nylon or glass fibre to horsehair, and brass or crimped steel wire.
There is a range of spiral brushes in two basic designs: single and double band.
Brush rollers are made in two designs: the punched design and the spiral design. Depending upon the function required the density of the brush is determined as well as the gauge of the fibre and the length of the fibre. Optimal results can be obtained with both straight and crimped fibres. Brush rollers are specially designed for cleaning units in the offset rotation print, for rubber cloth, back-pressure cylinder, humidifying units and brushes for the cleaning and washing of offset plates. If necessary brush rollers can be recovered.
(with inward-facing bristles)
Produced in a metal channel with the bristles pointing inwards.
This design version has many applications.
Measurements can vary from 20 mm outer diameter upwards, depending on the channel size.
It can be designed as a single ring or a complete spiral.
Can be used as a seal.
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.
It is important to use the double band spiral brush where it is technically appropriate, namely where heavy duty and hard bristle are used at high speeds.
The double band spiral brush channel consists of two metal strips, the outer strip holding the inner strip into place. The number and size of bristle tuft apertures can vary. This type of construction offers the advantage of providing different and accurately measured bristle tuft densities and 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 double band spiral brushes, is that should the brush be damaged, bristles are lost only from the site of the damage, whilst the remaining bristle tufts are clamped separately.
Double band spiral brushes are made to the required length with an internal diameter of 20 mm upwards. They can be supplied in various channel widths and with every type of bristle material.
