In emprime printing machines, paper surface is charged with static charge when paper bobbin is unwrapped. Paper attracts dust and particles until sent to drier before and after printing.These are undesired behaviours and result in lossy and incorrect production.

As seen in the figure, anti-static bar which is installed on input and output points of emprime machines will neutralize static charges on paper surface. Thus, printing is applied correctly and high quality and reliable printing is executed.

During the manufacturing of profile extrusion, large static charges are built up in two areas. Firstly, as the material cools, the molecules inside the profile will rub against each other causing static to generate. Secondly, as the profile passes across rollers or guide channels, this creates friction which will generate a static charge. This charge will create an electro magnetic field which will attract airborne contamination from the air on the product.

After cutting, the profile will attract the swarf from the saw which is difficult to remove. This will cause damage to the profile during packing, down time due to cleaning and reduce productivity.

By positioning two (one either side of the profile) PULSElectronic air boost bars after the saw, you can neutralise the profile while blowing the swarf off. The air boost bars should be positioned so the air is blowing against the direction of travel to ensure a clean profile prior to packaging.

Due to polymer make up of the print head and the very nature of Tampo printing, you are continually creating static on the head of the printer. This is due to friction and separation of materials and surfaces.

For the solution of this problem, By positioning either a PULSElectronic bar or nozzle in a position the will bathe the head in an ion field after each print stage, you will eliminate the charge, prevent spıderıng and fogging of print, increase productivity, reduce waste and improve profits.

By fitting PULSElectronic ionısıng nozzles to the stack, as the top sheet is grabbed to feed the machine, a blade of ionised air is blown between the top sheet and the penultimate sheet, which eliminates the charge and prevents blocking, sticking and jamming.

In bag production for forming handle part of bags, handle part is generated with a cutting knife system before cutting process. During this process air can enter in plastic which will cause incorrect cutting. This will lead to lossy and incorrect production.

For preventing this production problem, charging bar should be placed before cutting knife which has opposite charges.Thus, entrance of air and sticking of plastic that will be cut is avoided and a reliable production is provided.

When reinforcing the handles on plastic bags, a further sleeve is added for strength. This sleeve can repel from it set position due to static charges on ether the bag or the sleeve itself. This causes misalignment, wastage, down time and rejects.

After the sleeve has been positioned, you can induce a charge into the material using a PULSElectronic charging system. This will hold the sleeve while the thermo weld is completed and prevent wastage thus increasing productivity.

On any un-wind operation, as the web is pulled from the roll, you have material separation. As the surfaces separate, electrons from each surface will migrate from one surface to another. As the surface of the material is non-conductive, it cannot flow back and a static charge is now on the web. This charge will create an electro-magnetic field which in turn attracts airborne contamination onto the web causing rejects and wastage.

Another area of concern is the electro-magnetic field can be absorbed into the bodies of operators who work in close proximity. The operator will then discharge when coming into contact with an earth potential such as. Machine casing. Door handle or another operator. Although painful, the charge is in most cases not dangerous. The resulting involuntary reaction of the shock however, is dangerous when working close to moving machinery.

During the wind-up operation, any static charges on the web will cause the material to repel and not roll correctly and leave a record edge finish. This again can cause loss of product, waste and down time. The problem of operators absorbıng charges ınto theır bodıes ıs also prevalent here.

On both un-wind and re-wind the application is the same. By neutralising the charge on the roll you will remove all the possibility of material misbehaviour, dust contamination and operator shocks.

PULSElectronic pulse DC bars can be mounted to ionise the nıp of the roll. This will eliminate the charge on both sides of the web.

If you are unable to position a bar in that configuration, an ıonısıng blower can be mounted to bathe the reel in ıonısed air, which will neutralise the charge.

After the manufacturing cycle of a flat bag making machine, the bag will have built up large static charges from the un-wind. Friction of rollers and the heat from the thermo welding. Although highly charged, the bags are under tension and do not cause the manufacturer problems. When the bags are cut, the static charge then will cause the material to attract to an earth potential such as rollers. Machine casing etc. This is also a problem when trying to stack the bags. As the bags are manufactured from the same material and have been through the identical manufacturing process, they will hold the same charge. This will cause the bags to repel from one another and not stack correctly.

By positioning two PULSElectronic ionısıng bars (one ether side of the web) across the material prior to cutting, you will neutralise the charge and the bags will then stack correctly, reducing wastage. Down time and increasing productivity.

When magazines are printed they are conveyed and stacked on top of each other. This can cause major down time when rotating the stack as the magazines fall off.

By positioning a PULSElectronic charge system either side of the stack (positive one side, negative the other) you can induce a charge in to the stack and hold the stack in place for packing, rotating and binding.

In packaging machines while rolled film is unwrapped, static charge occurs because of decomposition. This static charge causes film to stick to the metal parts or itself so leads to incorrect and lossy production.

For preventing this situation, anti-static bar should be placed on sections in which roll is opened and packaging begins for neutralizing static charge. Machine will execute more reliable and efficient packaging in these conditions.
