Non-contact web cleaners were specifically conceived and designed to
neutralize electrostatic charges and remove unwanted particles of dust and
paper from rolls of plastic and metallized film, paper and corrugated board,
nonwovens, before the phases of printing, coating and laminating, rewinding,
and after the cutting phase.
It is well known that during various production processes, the above materials
become electrostatically charged, and therefore attract dust and dirt; paper
and corrugated board in particular, tend to release fine unwanted particles
during cutting and unwinding, which deposit on printing matrixes with
consequent devastating effects on the quality of the final product.
Web cleaners guarantee to eliminate all these problems, allowing optimum print
quality and impurity-free finished products.
Certain web cleaners simultaneously clean both sides of the web without
touching them. The cleaning heads (through which the material passes) generate
turbulent air currents, which produce short-wave vibrations in the web to be
The vibrations break the boundary layer along the web (created by the
high-speed running) removing the particles of dust and/or paper present on
either surface of the web.
The impurities collected by the cleaning heads are then sent via flexible tubes
to the filter/fan unit. Removing dust and any other contaminants from the print
environment is beneficial to every type of process not only improving print
quality but also increasing plate life, increasing machine speeds, improving the
general environment on and around the press for the operators, and reducing anilox
cell plugging and ink contamination .
