Belt-brushes
The belt brushes are a technical brush with a flexible belt base. Therefore, it has all the features of an industrial belt but transformed into a technical brush, that is, the belt brush.
It is a very technical brush that finds its introduction in industrial applications where material needs to be transported by pulleys, or where a surface needs to be worked with transverse movement.
In this type of brushes, unlike other technical brushes where the material and geometry of the base have fewer requirements than the filaments, as it is merely a support for the bristles, in technical belt brushes, the base, that is, the belt, plays an important role, and it is necessary to make an appropriate selection of its dimensions, geometry, hardness, and materials for the belt brush to work properly.
Belt brushes are the fundamental component of our transverse cleaner, in which the machine transmits the movement of the belts through a pulley system that positions the belts on a surface and performs a transverse cleaning of it.
The belt can be supplied closed upon itself if the desired length is known, or open if a belt brush is preferred that can be cut to length for each case and finally thermofused in assembly to the appropriate measure.

- Trapezoidal belt brush
These are the most common, and the belt base is a trapezoid where the filaments are inserted into the larger flat face (the upper one).
The typical belt sizes are trapezoidal type A, B, C, and D, and they are usually made of anti-abrasive rubber (typical automotive belt) or polyurethane.
Coatings or grip enhancement systems are not used, as they hinder the addition of filaments and it is very common for them to have an underside with teeth to gain flexibility and prevent damage when passing over pulleys.
Because the belt is multi-drilled to insert the filaments, internal textile reinforcements are usually not added.
- Flat belt brush
It is a belt brush that is much wider than trapezoidal belts, as it is flat. It resembles a plate brush but with a belt base. Like the trapezoidal one, the most common base materials are anti-abrasive rubber and polyurethane, and its most common application is transverse surface cleaning.
- Toothed belt brush
It is a variant of the previous two, where a flat or trapezoidal belt brush has an underside with teeth added for one of the following reasons: either to add additional flexibility to facilitate passage over pulleys, or to integrate it into toothed pulleys for high-power transmission applications, to prevent belt slippage, or when high synchronization between multiple movements is needed.
Belt technical brushes differ slightly from other industrial brushes regarding the filaments that can be used, as they are more technical and delicate applications. They predominantly use synthetic filaments with fine to medium hardness, and natural filaments, avoiding the use of metallic wires.
