Slitting and Rewinding

Full electrostatic control on high speed slitting/rewinding machinery

Slitting/Rewinding is a process to cut different type of jumbo roll’s with various material-width to narrower sizes at (very) high speed. This technique is suitable for several materials like paper, plastic film, flexible packaging, fabric or textile. The web is unwound and run through the slitter/rewinder, passing adjustable cutting knives, before being rewound on one or more shafts to form narrower rolls.

Slitting/rewinding your foil is usual business nowadays, because of the high speed and the number of rollers (friction), static electricity can create major problems.

Immediately after the slitting operation and before the winder, 24V Performax (IQ) Easy Speed antistatic bars will be installed. These static elimination bars will neutralise the static electricity generated during the previous unwinding and slitting process and will prevent:

  • New generated static during winding
  • Attraction of (cutting) dust
  • Employees getting shocks from static discharges
  • Telescoping effect on your slitted rolls

If a predefined low static level on the end-product is required, an in-line measurement system can offer this solution. To achieve this a Simco IQ Manager System can offer real-time managing and monitoring options with a full controlled Closed Loop Feedback system (CLFB)

This system monitors and controls all connected static eliminators and can be directly connected to the machine PLC via Fieldbus connection. This provides all information about efficiency and required maintenance of the static eliminators, as well as the static charge including alarms. In-line measuring and datalogging of electrostatic charge levels can be used in quality reporting.

These options contribute to increase static control of the process, operator safety and product quality, which all together results in high quality competitive slitting and rewinding.

Commonly Used Products

Performax IQ Easy

Performax IQ Easy

High performance combined with optimal static control. This is the new standard for antistatic bars. In combination with the Manager IQ Easy the Performax IQ Easy anti-static bar will ensure a very high efficiency of static neutralisation. Within the IQ Easy Platform up to thirty ionisation and charging devices can be connected in a network. Through the Manager IQ Easy it can be set up as a pro-active static neutraliser using the patented Up-stream static charge evaluation technique. Adding a Sensor IQ Easy to the system enhances the efficiency by measuring the downstream residual static charge and regulating the ionisation efficiency in real time to ensure a very low residual static charge.  The glassfiber reinforced profile offers a very rugged structure even up to 5 metres in length. The Performax IQ Easy has an integrated high voltage power supply and requires only a low voltage input of 24V DC. It is equipped with a standard M12 connector for the 24V DC input. Two 3 colour high brightness LED visualises bar ON (green), WARNING (orange) or bar ALARM (red). The Performax IQ Easy bar has light slanted ends and protection classification IP66 wich allows easy cleaning. Universal mounting brackets are supplied for various mounting options.

Manager IQ Easy

Manager IQ Easy

Manager IQ Easy Introducing a new level of static control; the heart of the new IQ Easy platform is the Manager IQ Easy. It comprises of a Control unit with a 7” LCD touch screen, provides information from all the connected devices and makes it easy to change and monitor status and parameters. Up to 6 IQ devices can be directly connected to the Manager IQ Easy. The 24V DC power distribution is routed via the Manager, so no extra cables! This makes the connection of a device even easier than connection to a single desktop power supply.
