ROLLMAX
Fig. 1 Close-up of the regulation wheel
ROLLMAX* is a patented expansion roller housing discs set at different angles. Each roller component rotates along its own axis and its angle of inclination can be adjusted both quickly and accurately by a handwheel.
ROLLMAX lets you optimise the expansion of fabrics, plastic films, paper and all ribbon materials in general. The fact that the system is made up of separate components means that roller parameters can be set to meet specific requirements.
Compared with other expansion rollers, ROLLMAX offers more even pressure over the entire contact surface avoiding dangerous tension or lateral pull that might damage the product being rolled. It is also well worth noting that rollers can be "expanded" during the rolling procedure.

ROLLMAX
ROLLMAX expansion rollers have been designed to provide perfect, evenly expanded surfaces over the full length of the
material being machined.
ROLLMAX is ideal for all ribbon materials such as fabrics, paper, plastic films and non-woven fabrics.
The new Ø 150 version can deal with lengths of up to 6 metres with the option of inserting a central support that decreases
deflection.
The roller has a steel or carbon fibre inner shaft that means it is lighter and vibrates and bends less.
Each disc consists of a resin bearing with stainless steel ball bearings for smooth uninterrupted running.

Functional principle
The ROLLMAX system lets you adjust
how much a material is expanded by
changing the angle of the inner discs
by turning the handwheel.
The expansion factor can be further
modified as required by fitting an
oscillating counter-roller that, apart
from increasing the tension, also
increases the angle at which the
material is coiled on the ROLLMAX to
provide even greater performance.
The shaft supports can be fixed (see
figure alongside), or be free at one
end and adjustable at the other by
means of a handwheel connected to a
reduction gear system. This allows for
faster adjustment by just one operator.

ROLLMAX
EXPANDER is a slatted roller that allows all ribbon material
surfaces to be expanded even under intense lateral tension.
Thanks to moveable lathes, EXPANDER ensures strong,
even pull over the whole surface to be treated.

ROLLDRIVERCENTRING ROLLER
ROLLDRIVER is a centring roller that, thanks to
constant electronic adjustment, guides the material
along the roller to facilitate centring.
Any distortion of the material is detected by sensors that instantly correct the angle of the discs that make up the
ROLLDRIVER to centre the material properly.
ROLLDRIVER lets you optimise the centring of fabrics, plastic films, paper and all ribbon materials in general. The fact that
the system is made up of separate components means that roller parameters can be set to meet specific requirements.
ROLLDRIVER is also available without electronics and can be customised to meet customer requirements.
