Polar to showcase high-speed cutting systems

At this year's China Print Polar will be exhibiting not only a standalone 115 PF cutting machine, but also the P-Net service Compucut in Chinese language, as well as two systems: Cutting System L-137-T and the Cutting System L-R-137-T PACE.

Cutting System L-137-T has been conceived especially for the pre-cutting of paper. A stack lift allows the operator to load the uncut material into the high-speed cutter at a favourable working height. The material is cut into the required format. After that, a Transomat unloading unit piles it, ensuring optimum ergonomic conditions. The material is easily pushed onto the transport pallet of the Transomat. This unit automatically deposits parted or complete reams on a pallet. Meanwhile the operator continues his/her cutting work. With its patented movable pallet tip the Polar Transomat achieves perfectly aligned edges so that the material can be directly processed on the printing press or folding machine. 

The automated PACE cutting system L-R-137-T provides an enormous potential for savings. Compared with a manual cutting system operated by two the high level of automation allows to obtain the same output with just one operator. 

PACE (Polar Automation for Cutting Efficiency) is a synonym for automated cutting processes. The loading, turning and waste removal operations are automated. The Autoturn turning gripper combined with the Autotrim cutter is the automation centrepiece here. While Autoturn automates the turning and positioning cycles of the cutting ream, the Autotrim feature automatically removes the waste cuttings. 

These two components interact and allow automation of the first five cuts (four-side and dividing cuts). While the cutting system is automatically cutting, the operator can conveniently prepare the next ream on the automatic jogger. A continuous workflow is ensured. This working method offers the advantage that the operator can carry out a quality control during the jogging process. Besides, it allows to easily process even materials which are difficult to handle. 

The P-Net service Compucut enables customers to streamline their working sequences at the high-speed cutter or cutting system even more. Polar Compucut generates cutting programs outside the high-speed cutter while it continues the production. This procedure is based on the sheet layouts transferred as PPF or JDF files from the prepress. Depending on the setup of the sheet, the program can be generated manually, semi-automatically or, ideally in a fully automated process. To ensure the best possible program cycle, cutting programs are automatically optimised adding the required comments, additional functions and information for the user. It allows the programming time at the high-speed cutter to be reduced to almost zero while the machine efficiency is greatly increased. 

In addition, Polar will be presenting its new PF high-speed cutter which has been customised for the Chinese market. This model is available with cutting width 115 and 137 are produced in China and for China. It's not just the design that is different, but compared to the Hofheim-manufactured high-speed cutters it also offers a reduced range of function.
