THE NEW SUEDING & BRUSHING MACHINE

"UNICA"
FOR BRUSHING & DIAMOND FINISHING

The NEW sueding & brushing machine "UNICA" can use abrasive brushes or sueding rollers
which rotate at a variable speed lets to obtain excellent sueding results both on knitted and on woven fabrics.
This machine is characterised by its high sueding efficiency due to considerable number of contact-points.
The new sueding & brushing machine "UNICA" is available in two different models;
UNICA 4 ; with four (4) brushes or four(4) sueding rollers,
and
UNICA 6 ; with six (6) brushes or six (6) sueding rollers;
on those machines the brushes can be easily
changed with sueding rollers covered with traditional emery or diamond tapes.
A new system let's change brush with sueding roller in just few minutes,
it is also possible to process the fabric with a combination of brushes and sueding/rollers covered
with diamond or traditional emery paper.

ADVANTAGES

The UNICA has three rotating groups, that lets achieve different working positions,
rotating each group, it can be changed the angle of touching of the brush or/and of the sueding-roller ;
on each group it is possible to install brushes or sueding rollers or combined, one brush and one roller.
The advantage of this machine is that easily can be replaced the brushes with a sueding roller just in few minutes;

This system gives the follow advantages:

"UNICA 6" offer many different combinations:
it is possible to use only brushes 2 or 4 or 6;
it is possible to use only sueding rollers 2 or 4 or 6;
it is possible to use four brushes on the right side of the fabric and two on the back side at the same time;
it is possible to use only three brushes or only three sueding rollers;
it is possible to use sueding rollers or brushes three on the right side and three on the back side at the same time;
it is possible to use only one brush or one sueding roller on the back side, meanwhile the other five are working on the right side of the fabric.
it is possible to use also the machine in many others different ways, satisfy all the requirement.
In case to use one brush and one sueding roller:
-to use only the brush or only the sueding roller without dismantling one of the the two parts ( if rotate the group let's touch only one of the two parts)
-rotating the group of 180° make be easier to change brush with sueding roller and vice versa.
The sueding rollers are made in light weight composite carbon fiber,
the carbon fiber composite has superior mechanical characteristics;
it has a great ability to decrease vibrations and let's obtain the desired characteristics of strength and resistance.
That give better production performances for the follow undeniable advantages:
" Lower mechanical load;
" Higher rigidity of the rollers;
" Greater longevity of their bearings;
" Higher rotating speed;
" Rollers less prone to bending in case of any fabric smash;
" Easier assembling and removal of the rollers because of their lower weight.
Each sueding roll is provided with a unique and simple system which provides a quick and safe clamping device to fix any kind of emery (diamond, paper, etc.)
(No glue is required to fix any kind of emery on the rolls)
Diamond tapes can be replaced several times on the rolls.

diamond tape are made without any joint, one entire belt very strong and resistent that can be
reinstalled on the roller many times and every time without damage it.
As on all Caru's machines, the sueding rollers can be made in light weight composite carbon fibre, which are more light and
strong, giving advantage of high rotary speed and easy

The sueding rollers are made in light weight composite carbon fiber, that assure a perfect stability.

Carbon is one of the most important elements on earth in that the entire organic, animal and vegetable world is based on the chemistry of its composites. Even though it is only present in low percentages in the earth's crust at approx. 0.03%, carbon, such as fossil carbon and petroleum, constitutes the most important source of fuel and chemical industrial products. The two crystalline forms, called allotropic, with low carbon density (weight/volume), diamond and graphite, have a special crystallographic structure, that at a macroscopic level generates superior properties of resistance to mechanical strains.

Why choose Carbon fiber?
The carbon fiber composite has superior mechanical characteristics. It has a great ability to decrease vibrations and by correctly directing the fibers, you obtain at each point the desired characteristics of strength and resistance. The other side of the coin is the extreme specialization and precise fields of use. The carbon fiber composite has a thermal expansion coefficient 50 times less than that of aluminum, therefore a great deal of attention must be paid to joining the aluminum and composites. This all requires a great design effort. The product must be studied in depth in the design stage. Finished elements analysis allows us to map the strains and therefore the correct structuring of the piece. Columbus has provided
in its assembly instruction manuals for the carbon parts, precise instructions to frame makers to avoid errors and problems.
