Static Control on Unwind and Rewind Rolls

As the roll diameter changes in unwind and rewind applications, the efficiency of a static bar will decrease as the static bar gets futher away from the roll.

The NEW Simco ROLL FOLLOWER , equipped with a high efficiency static control bar, is designed for permanent mounting to an unwind or rewind stand for continuous control of static electricity. Photo sensors included in the system detect changes in the outside diameter of the material roll and automatically move the static bar to maintain a predetermined distance to the surface of the roll, regardless of the web speed. When the roll is finished the static bar retracts to its resting position, away from the roll. The system PLC allows the operator to easily program the unit for either unwind or rewind functions. The result is maximum static neutralizing efficiency regardless of roll diameter throughout the entire unwind or rewind process.

Using an Electrostatic Charge for Ribbon Tacking

The Chargemaster System uses opposite polarity, high voltage DC charges to tack ribbons together. This action displaces the laminar airflow between ribbons and the ribbons gain strength from the intense but temporary static charge. The ribbons are now easily moved through to finishing with 'dog-ears' and creases prevented.

Using an Electrostatic Charge for Card Insertion on a Saddle Stitcher

On the saddle stitcher, many cards can end up on the bindery floor. The problem can be practically eliminated by immediately pinning the catalog closed once the card has been inserted. A charging applicator placed over the signature just as they close will trap the card in place preventing fall outs.

Static Control for Sheet Fed Presses

A strong static charge can cause sheets on the feed pile of a sheet fed press, or other sheet fed equipment, to stick together. This can result in multiple sheet pick-up and sheet registration problems leading to periodic press jams.

To fix the problem, R55 Ionizing Air Nozzles can be mounted at the top of the feed pile -fluttering the sheets with ionized air and removing the static charge that causes the sheets to stick together.

Electrostatic Charging for Card Insertion on Perfect Bound Line

On perfect bound lines, card inserts often overshoot the target area because of the speed of the line. Applying a static charge to the card as it hits the page effectively holds the card in place. The card will not slide into the spine and accidental gluing will be prevented.

Electrostatic Charging for Catalog Stacking

SIMCO Chargemaster BP-30 power supply and Pinner Superbar charge catalogs just prior to stacking. As a result, the catalogs become flat and snap onto the stack, electrostatically adhering to each other. The catalogs are held together in a tight, registered stack as they proceed through the overwrapping and shrinkwrapping processes. Jams and edge damage are eliminated and throughput rate is increased. Use of strapping equipment is reduced or eliminated.

Electrostatic Charging for Chill -Tack Systems

The Chargemaster system uses high voltage to pin the web to the chill-roll at the first point of contact. Pinning the web to the chill-roll prevents slippage and eliminates condensation streaking. Preventing slippage also reduces tension upsets and improves registration throughout the press.

Static Control on an Open Web

Static charges on an open web can attract dirt, shock operators and cause product defects. A Blue Bar will neutralize the static charges, eliminating production problems. The Blue Bar neutralizes static charges on webs at speeds to 2500 fpm at 1" and can be mounted up to 6" from the web at slower speeds.

Particulate Removal and Static Control for Sheets

A Simco Ion-O-Vac Mark I sheet cleaner is ideal for removing dust and particulate from sheets in a sheet fed press. The Mark I can improve productivity because fewer press stops will be required to clean the blanket cylinder. The quality of printed output will also increase because hickeys, voids and crows’-feet will be greatly reduced. Finally, the work environment will be cleaner: less paper dust and reduced spray powder contamination when sheets are run through the press multiple times.

Particulate Removal and Static Control on Corrugated Materials

CLEANING CORRUGATED MATERIALS

Slitter Dust, chaff from sheeting, and other environmental contaminants on the surface of the corrugated material make it impossible to achieve production goals and difficult to maintain quality print standards.

Neutro-vac Web and Sheet Cleaning Systems effectively remove slitter dust, chaff from sheeting and other contaminants from the surface of corrugated material.

CLEANING PAPER, FILM and FOIL

Slitting, sheeting, coating, laminating, bag making, and other production processes of paper, film, and foil materials create particles that contaminate the web.

SIMCO offers a wide variety of web cleaners. The one that is right for you depends on how clean you need your web surface. Most systems are configured with static bars that neutralize static charges and prevent reattraction of contaminates to the web surface.

Static Control on RFID Tags

RFID tags contain an antennae to enable them to receive and respond to radio-frequency queries from an RFID transceiver. The microchip contained in an RFID tag can be damaged by static electricity.

Static charges are commonly found in tag and label printing/production operations anywhere along the path from the feed-roll to the rewind. The charges are generated by the contact and separations of the web material from the unwind roll, and as the material travels over the various rollers and process stations as it runs through the press or converting equipment.

Unfortunately the tiny circuits of the RFID tags may not be robust enough to withstand exposure to static charges.

To protect RFID tags, SIMCO manufacturs several products to control static charges.

The Blue Bar provides relatively balanced ionization. The ionizing balance (equality of positive and negative ions) of the active eliminator is important because the offset voltage differential (usually negative) of some ionizers could cause damage. Balanced ionization will reduce the static charges quickly to levels that are no longer dangerous to the RFID tags, with negligible residual voltage. CLICK HERE for more information on the Blue Bar

The PerforMAX 3 is the most advanced static control system available for monitoring static neutralizing performance. PerforMAX3 provides outstanding extended range performance to eliminate static charges even when installed 2" to 10" from tags and labels. The PerforMAX3 system is available in several configurations. The standard system provides remote ionization monitoring and control, clean bar and system fault indicators, and remote on/off control. The computer interface configuration has remote computer monitoring and data acquisition. CLICK HERE for more information on the PerforMAX3

The fusION delivers powerful and balanced static control in a compact package that can be installed in places where typical ionizer designs do not fit. Simple to install, operate and maintain. No adjustments or calibration are necessary with Simco’s patented auto balancing (DOCC) technology. The biggest benefit for RFID applications is the this unit has a guaranteed ion balance of + or - 50m volts, and is specifically designed for use in electronics applications.

SIMCO’s Aerostat PC is an excellent choice for static elimination in RFID application when a static bar can not be used. The Aerostat PC is distinguished by its variable speed control, balanced ionization and patented emitter point cleaner, While helping to protect products and personnel from the effects of static discharge, the Aerostat PC is lightweight, small, and quiet - making it easy for the user to direct the ionization where it is needed. Best of all, this unit has a guaranteed ion balance of + or - 50m volt! CLICK HERE for more information on the Aerostat PC

Electrostatic Charging for Card Insertion on Perfect Bound Lines

On perfect bound lines, card inserts often overshoot the target area because of the line speed. Also, it may not exactly match the line speed hence the card may slide backwards which results in bad positioning on the package. Apply a static charge with the charging bar to the card as it hits the page to effectively hold the card in place.

Static Control for Silkscreening

The sheet pile at the feeder section of the printing machine may have a static charge which causes the sheet (substrate) to stick to the pile and misfed into the machine. Once the squeegee has realized its printing stroke and the screen is lifted, the substrate may stick to the screen, causing smearing. The substrate may also stick electrostatically to the screen bed and cause misalignment. Misbehavior on its path through the dryer, and incorrect piling at the delivery, attraction of airborne contaminants are all problems which Simco products can resolve, preventing rejects and machine stops.
