rollers can be changed very quickly – and makes maintenance and cleaning very convenient.” The working width of the AKHN-B ranges from 1300mm to 2600mm as standard and can be optionally extended to 3200mm. The take-off speed ranges from 150 m/min to peak values of 300 m/min. It also has a low overall height. In order to optimise the flatness, and further improve film quality, it is also available with an S-Wrap 1, S-Wrap 2 and S-Wrap 4 tempering unit. In terms of maintenance, the AKHN-B allows

agreed. “These two additional Goebel IMS slitter rewinders will give us our first 10.6m BOPET production line,” according to Xu Yongming, general manager of Zheijiang Yongsheng Technology. In addition, Goebel IMS has supplied 16 Monoslit 9000 BOPP slitter rewinders to Fujian Forop Advanced Materials – a leading producer of BOPP film – with the potential to supply slitters for a further six production lines. Forop intends to start two new production sites in southwest and southeast China by 2025 – for a total of six production sites with 30 BOPP produc- tion lines. This will boost the production potential of the group – which says it intends to become the world’s largest producer of BOPP film.
Taking off Hosokawa Kolb – a subsidiary of Hosokawa Alpine of Germany – has developed the AKHN-B, a standard film take-off unit with modular design and optional S-wrap tempering unit. “The take-off is particularly user-friendly thanks to optimised accessibility of the components,” said Michael Buchauer, managing director at Hosokawa Kolb. “We have done away with the separate control cabinet for the AKHN-B. This means that

easy access to the interior through the sliding doors, a smaller number of crossbars in the frame, and a decentralised drive concept. It has also been integrated into the ExVis process visualisation system. “Film recipes with the corresponding operating
data are stored in ExVis and can be called up at any time,” said Buchauer. “These are stored at a central location and can be imported into all Hosokawa Kolb system components.”
Label production Colognia Press, a Czech-based label converter, has installed an MBSF unwind splicer and LRD rewinder with slitting capability from Martin Automatic. The new equipment is fitted to a Gallus Label- master 440 press at its facility in Kolin. It joins previous Martin nonstop unwind and rewind technology fitted to Colognia’s Gallus RCS 330 presses in 2010 and 2015. “Around 50% of our output by volume is self-adhesive labels, with blank labels and lami- nated tubes making up another 30%,” said Dušan Prevrátil, production director at Colognia. Martin’s ability to adapt its technology to any
situation was seen when the new equipment was fitted. Due to space restrictions, Colognia had been forced to install its Labelmaster with the operator side close to an external wall. This left insufficient space at the infeed end of the press for the opera-
