About the Web Converting Process

Web Converting is combining materials such as paper, plastic or foil into new intermediate or final products. For example, conversion equipment might cut a web of plastic film into lengths and fuse the edges, thus creating plastic bags. Coating and printing, typically, utilize conversion technology. The former can include deposition, hot coating, curtain coating and slot-die coating. The latter, such as Flexo and rotogravure printing, is suited to high speed roll-to roll-processing.

These and other web conversions require controls to ensure the greatest yields and fewest rejects. Tension control, for example, applies to the unwinding of rolled material before it moves through a machine, and is achieved with an expandable airshaft that holds the core of the roll, with an attached brake to control roll rotation, and a tension-measuring sensor.

Keeping web material aligned and on track during conversion is another important control, achieved by web-guiding systems positioned upstream from the most critical stages in the web conversion machinery.

But as critical as they are, tension control and web alignment are just two of the needs essential to web conversion technology that the products described here address.
