Sheet and Web Cleaners

Removing particles from sheets.

dirty clean blanket newA 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.

Clean web surfaces including corrugated materials

CLEANING CORRUGATED MATERIALS

 Dry end of Corrugator after SlittingSlitter 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.

We offer 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.

Air Nozzles

Selecting  Ionizing Air Nozzles and Curtain Transvectors

Air nozzles removing debris from inside of cansSIMCO's ionizing air nozzles are  ideal for delivering ionization into inaccessible trouble spots, such as  isolated, hard-to-reach sections, dirty areas, or small spaces. Operating on  compressed air, nozzles provide a highly efficient pinpoint source of  ionization to neutralize charges in very specific spots, often several inches  away from the nozzle tip. At the same time, dust, dirt, and particulate are  blown away from the targeted surface. Available in four styles, the nozzles can  be arranged in many configurations to accommodate space limitations on  industrial machinery. They are available individually or optionally mounted on a  standard air bar header.

Simco's ionizing curtain transvectors provide an additional alternative to  static bars when a powerful "air curtain" is desired for simultaneous cleaning  and neutralization. Operating on compressed air, the ionizing curtain  transvector is designed to direct stream or "curtain" of ionized air at a very  specific area.

The forceful air curtain operates like a knife to remove dust and dirt from  targeted surfaces while the ionized air prevents the reattraction of  contamination.

Static problems on sheet fed  presses.

Ionizing nozzle preventing multi-sheet pick up from feed pile on pressA 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 pickup and  sheet registration problems leading to periodic press jams.

To fix the  problem, a series of R55 Ionizing Air Nozzles can be mounted around the top of  the feed pile - fluffing the sheets with ionized air and removing the static  charge that causes the sheets to stick together. You will have higher output and  fewer headaches.

Clean with Magnum Force before  painting

Magnum Force cleaning prior to painting
Use Magnum Force to clean dust and  dirt from surfaces before they are painted. It is ideal for auto bodies and  appliances, as shown in the accompanying photo, because air knives and air  nozzles can be positioned to clean hard-to-reach places.

Conveyostat neutralizes slitter  trim

Conveyostat prevents jams in cyclonesHighly 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 neutralizes trim  materials prior to entering the cyclone. Once neutralized, the materials flow  smoothly throughout the system, eliminating system shutdown.

Slitting and rewind

Phoenix Ionizing Blower at Slitting and Rewind applicationStatic charges can cause trim fragments and fibres to stick to films after slitting.  The dirty, charged roll may cause productions slowdowns, poor product quality and even rejected product.
A Phoenix Ionizing Blower installed above and 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 adhered to the film.  As a result, neutralized materials stay clean and dust free, dramatically reducing slowdowns and rejected rolls, and improving overall quality.

Static Bars

Static charges on a high speed web

PerforMAX 3 on High Speed ApplicationsThe PerforMAX IQ Static Neutralizing System uses a new patented technology that allows the bar to produce greater amounts of ions and project the ions greater distances than other static bar systems.  The PerforMAX IQ actually senses intensity and polarity of the static charge and varies the power and polarity of the static bar to neutralize the charge quickly and effectively.
In addition, the PerforMAX IQ 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 eliminator may not be enough:

*  Winders or rewinders, where material is often far away from the static bar due to web path restrictions
*  High speed webs -- the PerforMAX IQ can handle speeds up to 2500 FPM 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

Controlling static on fibre optics

BlueBar used to Neutralize Fibre OpticsStrands of optical fibres 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 BlueBar to neutralize the charges from the fibres.

Static control on an open web

BlueBar used to neutralize Static on Open WebStatic charges on an open web can attract dirt, shock operators, and cause product defects.  A BlueBar will neutralize the static charges, eliminating production problems.  The BlueBar 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.

Form fill and seal

BlueBars used at Form, Fill, and Seal MachineVertical form, fill, and seal operations often result in rejects of the finished package due to product fines attracting to the film in the seal area.  BlueBars positioned just below the tube neutralize the film, resulting in not attraction of fines and a clean seal.

Remove static charge from a  roller

BlueBar Removing Static from Rollerstatic on roller newIn a paper mill, a rubber  calendar roll was generating a 20 kV static charge. As a result, dust and debris  in the air was attracted to the roll. This caused impressions from the  contaminants to be transferred to the paper.  An R50 Blue Bar, connected  to a TrueAC  Power Supply, was installed facing the roller along its entire  length. The Blue Bar took the charge off the roller and helped keep  contamination off the roll.

Static control in an  accumulator.

BluBars used on accumulatorStatic charges can build up on a  web in an accumulator. When charges become to high, the web may attract to  itself or other surfaces, and the accumulator may not extend to its full  range place R50 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 wicketer

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

Static Generating

Binder  or Video Cassette Cases

Static pinning used in binder manufacturing3-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. Chargemaster powered 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.

Card  Inserts

Card insert Perfect Bound newOn 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.

Chargemaster pinning card insertsOn 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 Chargemaster powered Flextac applicator  placed over the signature just as they are inserted will trap the card in place preventing fall outs.

Catalog  Stacking

Chargemaster pinning catalog stackSIMCO 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 over wrapping and shrink-wrapping processes. Jams and edge  damage are eliminated and throughput rate is increased. Use of strapping  equipment is reduced or eliminated.

Chill -  Tack

Chargemaster pinning web to chill rollChill-Tack System
The ELTEX  Chill-Tack System is designed for heat-set web offset printing presses. The  Chill-Tack 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.

Chill Roll Edge Pinning on  Cast Film Lines

Chargemaster edge pinning filmA SIMCO charging applicator at each edge of  the roll powered by a Chargemaster applies a static charge to the extruded film as it contacts the chill  roll. The static charge effectively prevents 'neck-in' of the film.

Dry-Bonding  Lamination

Chargemaster dry bond laminationChargemaster 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.

In-Mold  Decorating

Chargemaster for in-mold decoratingStatic charges from Chargemaster can be used to pin a  decorative decal tight against the inner mold surface during injection molding,  a procedure which greatly improves finished product quality. A decal is placed  by robot into the mold cavity. An electrostatic charge is applied simultaneously  as label vacuum is turned off. The static charge pins the decal to the mold. The  decal will not slip or change position in the mold.

Interleaving

Chargemaster for interleavingChargemaster pins the protective sheet  to the base material, holding it in position through the shearing and stacking  processes. Chargemaster equipment supplies the electrostatic force to bond a  protective layer of paper or film to cut sheets of metal, glass, wood, and other  products. Chargemaster is also used to hold wood laminates to core board prior  to thermal bonding of desk tops and panels.

Plastic Bag  Processing

Chargemaster removing air from bagsThe 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.

Ribbon -  Tacking

Eltex Ribbon Tacking SystemRibbon-Tracking System
The  Eltex Ribbon-Tacking 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.

Top of Page


Roll-to-Roll  Changeover

Chargemaster for roll to roll changeoverChargemaster 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.

Top of Page


Shrink  Wrapping

Chargemaster for shrink wrappingAn electrostatic bond holds sheets of paper  or plastic in place until the heat sealing or welding is completed. Chargemaster applies an electrostatic charge to bond sheets together to keep them in a tight  stack. This prevents the film over wrap from pushing the top sheet out creating a  shingling problem. Imperfect packaging and damaged sheets are also  prevented.

Static Blowers

Injection molding

Phoenix Ionizing Blower used to Neutralize Injection Molded PartsInjection molded parts can have high static charges which attract airborne contamination, resulting in product rejects.  Operators may also experience uncomfortable shocks working next to the collection bin,
The Phoenix Blower provides ionization to quickly neutralize the molded parts.  As a result, the parts no longer attract airborne contaminant and remain clean while operator shocks are eliminated.
