Ace Electrostatic Contact Web Cleaning

“Your partner for electrostatic and web cleaning solutions”

The Flexo Factor proudly offers “contact” cleaners, which have been specifically designed to neutralize electrostatic loads and remove contaminating particles of dust attracted by reels of plastic films.

​The presence of these contaminating particles results in non-conforming products, and in particular if intended for the food, medical and pharmaceutical industry. The use of AR 800/1S – AR 800/2S cleaners guarantees less waste and improved quality.

Original monitoring systems, means that these innovative contact cleaners avoid well-known problems revealed to date by traditional cleaning systems with adhesive rollers. 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 effectson the quality of the final product. Web cleaners guarantee to eliminate all these problems, allowing optimum print quality and impurity-free finished products.

NON-CONTACT WEB CLEANING

The type AK 1000 and type AK 3000 non-contact sheet cleaners were specifically conceived and designed to remove unwanted particles of dust and paper from sheets and plates of plastic films, paper and corrugated board and tissue.

The web cleaner simultaneously cleans both sides of the web without touching them. The cleaning heads (through which the material passes) generate turbulent air currents (blown and sucked), which produce short-wave vibrations in the web to be cleaned. 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 cabins (sound-proofed cabins with filter/fan unit). The cabins are equipped with special regulating devices that ensure the optimal dosage of blown and sucked air, according to the materials to be cleaned.

STATIC / ANTI-STATIC WEB CLEANING

TheFlexoFactor offers the ROTOSTATIC “Top Loading” system, at the inlet side of the printing unit, the material to be printed (paper or film) is neutralized by the first ACE antistatic bar, type BN, with a strong de-ionizing effect, in order to eliminate any static electric charge that may be present.

After this, the special static bar type DE R40, located above the pressure roller creates an intense, homogeneous electrical field in the semi-conductive layer of the sleeve/rubber pressure roll itself. The electrical field is then transferred from the pressure roller to the impression cylinder so as to guarantee a specific polarization of the ink present in the cells, and consequently a perfect transfer onto paper or film to be printed. The second antistatic bar, type BN, with a strong de-ionizing effect is positioned at the outlet side from the printing unit, so as to eliminate completely any static electricity present in printed material.

TheFlexoFactor offers the ROTOSTATIC “Direct Charging” system, at the inlet side of the printing unit, the material to be printed (paper or film) is neutralized by the first ACE antistatic bar, type BN, with a strong de-ionizing effect, in order to eliminate any static electric charge that may be present.

After this, with the DC 50 (direct charging system) the charging of the sleeve/rubber pressure roll is made directly from the core and then transferred to the external semi-conductive surface. The electrical field is then transferred from the pressure roller to the impression cylinder so as to guarantee a specific polarization of the ink present in the cells, and consequently a perfect transfer onto paper or film to be printed. The second ACE antistatic bar, type BN, with a strong de-ionizing effect is positioned at the outlet side from the printing unit, so as to eliminate completely any static electricity present in printed material.

The “Missing dots” is an extremely common quality problem in rotogravure printing; “missing dots” are those points in the print where the ink (having been only partially emitted from the cylinder cells) has not been perfectly transferred to the substrate (paper or film) to be printed.

The Rotostatic system of “electrostatic printing assist” guarantees complete and accurate ink transfer to paper or film, even at higher production speeds, without the need for excessive roller pressure.
TheFlexoFactor also offers a full range of cleaning solutions that have been developed to enhance the ultrasonic cleaning process. Our cleaning products are environmentally safe, ozone friendly, non-hazardous aqueous, (zero VOC) and solvent based solutions that have a low rate of evaporation. They are suitable for all ink and adhesives ,UV-cured inks, water and solvent-based inks. Additionally, we offer manual cleaning products.
