Rofin, Daventry, Northants, UK, has added in process vision inspection to its web movement compensation (WMC) system.

Rofin’s high speed StarPack Web Direction System consists of a 600W CO2 laser, with up to four individual WMC heads. In this configuration, web widths of up to 1.8 m can be accommodated with production speeds in excess of 350 m per minute.

The vision system captures images on-the-fly and checks hole diameter and percentage roundness. The system can be set to alarm if a pre-set number of holes are out of specification, thus ensuring that the perforated film which is delivered to the end user meets the exacting standards required to maintain product freshness and shelf life.

Rofin laser perforation systems have been developed by product designers with more than 30 years of experience in processing materials on web systems. Rofin uses its own laser sources as a starting point and matches them with optics, scanner heads, machines and software to provide the optimum technical solution. A graphical user interface allows user-friendly control of the entire system, including previews of possible perforation and scribing speeds.
