Straight knives from DIENES<\/h2>\n\n\n\n

With our long parts, DIENES customers can rely on the lowest manufacturing tolerances in the \u00b5m range. Polished cutting edges also ensure an efficient reduction of dust and operating noise and additionally contribute to an increase in tool life. Close monitoring of production, detailed control reports and continuous further development also ensure the highest level of quality at DIENES in the straight knife sector. All products, including our guillotine knives, stack cutters, three-knife trimmers and trimmer knives, are supplied individually after detailed consultation with the customer.<\/p>\n\n\n\n

Our knives are manufactured in all qualities in compliance with the tightest tolerances. The tool steel knives are absolutely uniformly hardened, repeatedly straightened, cleanly machine-sharpened and honed. The finish is the same for all qualities carefully.<\/p>\n\n\n\n

Use of the guillotine knives, stack cutters, three-knife trimmers and trimmer knives <\/h2>\n\n\n\n

Our guillotine knives, stack cutters, three-knife trimmers and trimmer knives are designed for optimal industrial use, especially in the paper, packaging and plastics industries. Three-knife trimmers and trimmer knives are at home in advertising printing, such as cutting flyers. <\/p>\n\n\n\n

We manufacture guillotine knives for perfect cutting in the paper and pulp industry and print finishing. There are three main cutting types and all others work according to one of these three basic variants.<\/p>\n\n\n\n

The punching cut in cutting bar is used in all guillotines-quick cutters and 3-knife automatic machines. The system is based on the fact that the knife makes a downward pulling movement and plunges into a plastic bar built into the machine table.<\/p>\n\n\n\n

In addition, this type of knife is used in the shear cutting process. Here, the upper knife works against the lower knife, whereby the upper knife is movable and the lower knife is fixed. This system is used almost exclusively in print finishing (trimmers). Trimmer knives are usually manufactured in high-alloy tool steels (WS 1.2436, 1.2979 or DPM). <\/p>\n\n\n\n

There is also the rotary cut. This is characterized by the rotating upper knife that works against the fixed lower knife. The upper knife is inserted into the knife drum in a twisted manner, which creates the shearing angle that reduces the cutting forces to a minimum.<\/p>\n\n\n\n

General explanation of the paper cutting knives<\/h2>\n\n\n\n

The structure of the steeled knife is specified according to DIN 8869. Deviations from this standard are possible. The steel-plated knife consists of a carrier material and a hardened cutting surface. The hardened cutting surface, in turn, can vary and be designed in a wide range of qualities:<\/p>\n\n\n\n
