Brushes for Wood and for Brushing Machines

Brushes for the Treatment and the Finishing of Surfaces in Wood

SIT, Societa’ Italiana Tecnospazzole SpA, leader in the production of industrial brushes, considering the growing request of brushed products in the wood sector, introduces a new range of articles designed with our customers.
For the Aging-effect/Texturing we produce brushes with the following filaments:

Crimped Steel of different sections, between 0,20 – 0,50 mm
LIZ Iron Cord, available in two sections: 0,175 and 0,25 mm
Abrasive Nylon in the grits 46 – 60 – 80 – 120 – 180 – 320

For Dust removal and the Distribution of paint use filaments that have the peculiar property to not charge electrostatic while in use, like:

Horsehair
Tampico (plant fiber) that also has a very light abrasive function of finishing.

The Cylindrical Brushes can be manufactured with different diameters and lengths, as well as with different filaments based on a custom design

Types of Wire

Iron

Indicated for light jobs, for surface roughening. Can be used with high rotation speed, long life service and very good quality/price rate. In the wood sector it is the ideal for brushing machines on polished or laminated wood.

Liz Iron Cord

Composition of high quality carbon steel wires with brass surface coating.
It offers very high breaking loads and very good dimensional stability. To scratch wood and rubber obtaining predetermined surface finishing.

Abrasive Nylon

High resistance and hardness. It preserves the shape and resists very well to abrasion. It is similar to Nylon 6.12 but abrasive. It is used to debur metals, plastic materials and it is also very effective for sanding the wood and roughen the surfaces.

Horsehair - Animal fibre

Not subjected to static electricity. Excellent in cleaning and dust removing. Beside for brushing surfaces of polished and laminated wood it is used for dry seals and for applying liquids.

Tampico - Plant fibre

Not subjected to static electricity. Used mainly for the superficial processing of wood, for polishing metals and for seals at high temperatures.
SIT is starting to develop abrasive linear ragged brushes using filaments in tampico, that are currently used in sanding of raw and painted surfaces. It will be our care to present these products to our customers, as soon as we will be able to provide a range of products that satisfy many of the current needs.

Characteristics and Variables for the Treatment and the Finishing of Wood materials

The secret that allows users of the SIT brushes to obtain the desired result on different wood materials, depends on a few parameters, enlisted here below:

Advancement speed of conveyor belt, which carries the profiles that need to be treated superficially

Number of brushes in the series

Type of filaments

Length of filaments

Winding pitch (for spiral brushes) or pitch between the holes (for punched brushes)

Interference between the filaments and the surface of profile being worked

Brush rotating speed

Brush rotating sense: towards or against the profile feed direction.

Testing Room and Aging-Effect brush

Machine for wood-aging wood and area test

Inside SIT we installed a TESTING ROOM with a 4 brushes rustic touch/brushing machine, manufactured by a leading Italian manufacturer, and with many different brushes. This machine, originally manufactured for the superficial processing of parquet, has a working tape 400mm wide. The brushes, bounce mounted, offer the possibility to test profiles much wider than the 400mm tape width; the max operating height of the machine is 80 mm, therefore this is the maximum thickness of the profiles to be tested.
