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.

Static Control for Slitting and Rewinding

Static charges can cause trim fragments and fibers to stick to films after slitting. The dirty, charged roll may cause production slowdowns, poor product quality and even rejected product.

A SIMCO Phoenix™ Ionizing Blower installed above and just after the slitting operation directs the ionization at the film and trim fragments.Static charges are eliminated during the slitting process, preventing fragments from being reattracted to the film. As a result, neutralized materials stay clean and dust free, dramatically reducing slowdowns and rejected rolls, and improving overall product quality.

Static Control for Pneumatic Conveying Static Removal

Highly charged slitter trim materials cling to the sides of the cyclone of the trim collection system, forming a clog across the exit duct. The trim collection system must be shut down - affecting all operations producing slitter trim. The Conveyostat system controls static on trim materials prior to entering the cyclone. Once neutralized, the materials flow smoothly throughout the system, eliminating system shutdown.

Electrostatic Charging on Dry Bonding Web/Sheet Lamination

Chargemaster power supplies and charging bars work to bond the substrate and the laminating material. The materials pass between the two bars without contact and are electrostatically bonded. This ensures that materials remain aligned during the lamination process.

Using an Electrostatic Charge for Roll-to-Roll Changeover

Chargemaster applies a temporary charge to the leading edge of the roll of film at rewind. The edge then adheres to the core without the use of tape or messy adhesives. Finished product quality is enhanced by elimination of creases in the roll of film caused by tape and glue on the core.

Using an Electrostatic Charge on Binders and Video Cassette Covers

3-ring binders, cassette cases, and other types of binders are assembled in layers. The seal process requires that the layers stay in the position in which they were placed. Pinner bars strategically located over the assembly table allow pinning the materials together before the seal process to eliminate rejects. The various layers of the structure are held in their correct position.

Static Control for High Speed Web

The NEW PerforMAX 3 Static Control System is capable of neutralizing charged materials traveling up to 2,500 feet per minute, and faster depending on conditions.

In addition, the PerforMAX works well in all types of applications and neutralizes even very high levels of static charges. It is particularly well suited for difficult applications, where a traditional static control bars may not be enough:

• Winders and rewinders, where the material is often far away from the static bar due to web path restrictions
• High speed webs — the PerforMAX can handle speeds up to 2500 feet per minute and more
• Over open webs where it is inconvenient to locate the static bar close to the web
• In applications where the operation of the static eliminator must be closely monitored

Static Control for Fiber Optics

Strands of optical fibers can produce high static charges when wound onto a spool. This prevents the strands from laying properly on the spool, slowing down production. The charges can also damage the cable.

Use a Blue Bar to neutralize the charges from the fibers.

Static Control on Rollers

Particulate is attracted to a charged rubber roller causing impressions from the contaminant to be transferred to the paper. A Blue Bar installed facing the roller takes the charge off the roller.

Static Control on Accumulators

Static charges can build up on a web in an accumulator. When charges become too high, the web may attract to itself or other surfaces, and the accumulator may not extend to its full range.

Place R51 Static Bars, which are very high output bars, in the open areas between the folds of the web (see diagram). If the opposing sides of the web are within 2" or 3" of each other, mount the bars with the pins pointing up. This eliminates the need for two static bars within one fold. Further than 3", two bars may be required within each fold.

Static Control on a Wicketer

Static charges can make bags stack poorly, decreasing production yields and increasing rejects. Because of its extended range and high ionization output, the Blue Bar can neutralize static on materials several inches away, eliminating the static charges responsible for stacking problems on the wicketer.

Electrostatic Charging for Bagmaking

The speed of the conveyor can cause the lead edge of the bag to lift up and shift. Electrostatically pinning trailing to leading edges prevents lifting and keeps bags proceeding smoothly along the conveyor line. Chargemaster can also be used to remove air from bags prior to packaging. The reduced thickness allows the use of smaller, more cost-efficient packaging.

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.

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

Static Control on an Extrusion Line

SIMCO's Ionizing Blowers installed above the film directs the ionization at the film. Static charges are eliminated during the rewinding process, preventing ambient contaminants from being reattracted to the film.

As a result, neutralized materials stay clean and dust free, dramatically reducing slowdowns and rejected rolls, and improving overall product quality. The elimination of the static charge also eliminates “operator shock” to your employees.
