Case History An Illinois Tool Works Company The “Blue Bar” Outperforms Traditional Static Control Devices on a Wicketer 2.5 Traditional Bars 2 kV Blue Bars 1.5 1 0.5 2 3 Te st 4 1 Te st Te st 3 Te st Te st 2 0 1 Solution The patented Blue Bar is capable of neutralizing static on materials several inches away and eliminating the static charges responsible for stacking problems on the wicketer. During a well-controlled trial on a wicketer, two Blue Bars were proven to be more effective in controlling static than three of the traditional neutralizing bars. Using a hand held field test meter, residual voltage on the stacked piles was monitored. Results Using the Blue Bar system, the wicketer could operate efficiently with the neutralized bags hitting the pins accurately and at the rate necessary to maintain desirable production speeds. Again proving that the Blue Bar System is The Most Effective Static Elimination System in the Industry. Te st Problem Competitive static elimination bars are not always very effective in the control of static electricity on wicketers. Bars often have to be placed up to 6 inches away form the process. At times, several static control bars have to be in place on the application to achieve effective control. Results show that residual static (voltage) on the bags was 86% lower with the Blue Bars than with the traditional bars – resulting in more effective static control. Te st Background In the plastic bag production process, the wicketer can be a problem spot. Because of high amounts of static electricity, bags stick together during the stacking process, decreasing production yields and increasing rejects. This lost time and production can become very costly to the manufacturer. 2257 North Penn Road Hatfield, PA 19440 Tele: 215-822-2171 Fax: 215-997-3453 Web: simco-static.com Residual Voltage on Stack using Traditional Bars vs. the Blue Bar System
