Brand new, fully automatic “Twin Cut” slitting system<\/h2>\n\n\n\n

DIENES presents its brand-new, fully automatic slitting system “Twin Cut”, which can process paper, films, plastics, nonwovens and many other demanding materials with “non-compression” knives arranged in pairs. <\/p>\n\n\n\n

In the case of cross cutters, the trend in cutting multilayer papers is towards ever higher basis weights without restricting the previous cut edge quality. This requires the most stable knife holder designs and special cutting edge geometries, which must be precisely matched to the respective material to be cut. Depending on the paper grade and number of layers, the limits of classic shear cutting are 600-800 g\/m\u00b2 basis weight. The objective of many users is to increase this to 1000 g\/m\u00b2. However, this requires a double longitudinal cutting station, which is associated with considerable additional technical effort and costs.<\/p>\n\n\n\n

To avoid this high expense, DIENES has modified the shear cut process. In this process, both top and bottom knifes are driven. With pneumatically operated knife holders, the rotation of the top knife is effected by the friction of the driven bottom knife. This has a detrimental effect on the quality of the cut edges of very sensitive materials, such as paper of the smallest grammages, aluminum foil, and multilayer papers. In order to avoid this, DIENES has developed driven top knives in a wide variety of versions. The innovative principle is based on the use of a pointed circular knife instead of the classic bottom knife.<\/p>\n\n\n\n

If required, DIENES will also be happy to further develop the Top to Top cutting process specifically for edge trimming.<\/p>\n\n\n
