Vario Cut straight knife

Expand. Variability.

Innovative strength for professional slitting solutions has always been the forte of Dienes. With our new patent pending paper cutting knife VARIO-CUT, print shops and machine manufacturers benefit from a knife system which provides a whole range of advantages. Due to its unique, two-piece design, a broad selection of angles and grindings and an unrivalled low blade weight, this knife sets new standards in efficiency, variability and safety.

The new VARIO-CUT is a combination of blade and knife holder and compatible with all standard machines for guillotining - ideal for everyone wishing to optimise the quality and cost-effectiveness of their machines. The innovative, two-piece design of the inventor R. Rieder is in a class of its own - if a knife replacement is required for other material to be cut, the blade does not need to be positioned and aligned due to the fixed knife holder. The variable blade itself is available with various angles and grindings and can thus be flexibly adapted to the respective application. Due to optimised grinding and a 14.55 % lower blade thickness, the sliding friction could be reduced by 70 %, requiring significantly less force during cutting. The result: improved service life, easier cutting through thick material, less wear and more reasonable regrinding of the blade.

Above all, the remarkably low weight is an absolute novelty. Responsible for this is the separation of knife and holder as well as the tapering of the blade - the whole system of knife holder and blade weighs 23 kg, but the weight of the blade itself is a mere 10 kg. This corresponds to half the weight of conventional knives for guillotining, which are usually 20 kg heavier. The benefits are obvious: While a traditional knife replacement used to take up to 30 minutes, with VARIO-CUT a replacement of the blade is possible within just a few minutes by only one person. This not only means increased productivity and safety, but also longer service life of the knives, as the right blade is always used for the respective material due to the easy knife replacement. And despite minimal additional costs of the system, the bottom line is higher slitting quality, better cost-effectiveness and a faster return of invest. Another benefit: Due to the easy knife replacement, the blade can also be cleaned outside of the machine. Incidentally, the new paper cutting knife VARIO-CUT is also highly efficient with regard to repeat orders. The knife has a QR code, which forwards to our online service page, providing information on angles, grindings, spare parts, order numbers and documentations, and direct access is provided to the time- and cost-saving DIENES regrinding service.
