“It was important to develop a digital press that would meet the current and future needs of a flexible packaging printers,” said Hermann Veis- mann, managing director for printing at W&H. “We didn’t want a press for single or niche products, but for our customers’ entire portfolio.”
Film inspection Isra Vision recently enhanced its optical inline inspection system for polarisation films. The company has equipped its Smash system with a new sensor that improves the detection of typical defects such as scratches and perforations. Thanks to a special extra lens, the polarisation angle of the camera can be automatically changed. Pre-configured, product-specific profiles can be transmitted online to the camera. There is no need to stop production when making adjustments – which further optimises inspection performance and product quality while saving time and cost. The system offers automatic surface inspection for optical films such as prism films, polariser films, protective films and window films. High-resolution line-scan cameras and lighting technology help it to recognise even the smallest defects – even at line speeds up to 150 m/min. The trainable defect classifier QuickTeach helps to simplify and accelerate system start-up. The system also includes a set of tools for data record- ing, analysis ad reporting functions. The polarising filter used for inline inspection allows automatic adjustment of the polarising angle in the event of phase changes in the film. It sets the polariser to full-light extinction or other predefined settings without the need to stop production. Because the camera always receives an optimum input signal, defects can be recognised even more efficiently and reliably, says Isra. This helps to optimise product output and raise quality. Product- specific settings can be pre-configured

as recipes and transmitted online to the camera during operation. Compared with the manual setting of the polarization angle, the automatic adjustment ensures higher precision and saves both time and money. Using the new filter, the waste generated during
production start-up can typically be reduced by up to 1,000 sq m for each eight-hour shift, depending on roll width and line speed. This increases the amount of saleable product and protects resources by reducing material consumption and production waste.
Static bar UK-based Meech has launched a new ionising bar for static management. Its 945IPS Hyperion neutralises static build-up
across large production areas, which can reduce the hazards caused by static electricity in settings such as packaging machinery. Designed for applications of 150-600mm, the
product claims to improve safety and product quality while boosting productivity. It can be used on both high-speed production lines and in specialised operations. Its dimensions of 30 x 67mm make it easy to install on printing and converting machinery, while its pulsed DC output (up to a maximum of 15kV) helps to reduce the need for maintenance. A key part of the new system is its use of pure titanium emitter pins, chosen for their high corro- sion resistance and durability. These, combined with an optimised mounting system with a wider M4 T-slot and innovative T-slide design, ensure a secure, stable installation, it says.
Clean break Nilpeter Asia Pacific, which manufacturers printing equipment, recently launched its FlexClean non-contact web cleaner – which integrates 1100 AC anti-static bars from Fraser Static Control.
