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

DIENES is the world’s leading precision supplier of knives, circular knives, knife holders and slitting systems. In the field of knife holder technology, we offer a wide range of designs with different locking methods. Thanks to our comprehensive quality controls, we guarantee the sustained performance of the cutting tools as well as grooving knives with the lowest tolerance deviations, enabling high cutting edge quality. DIENES offers several types of grooving knives: Type NN (grooved knife with smooth bore), NG (grooved knife with eccentric locking), NS (grooved knife with screw locking). All locking methods contribute to quick and easy cutting width adjustment, but differ in operability. <\/p>\n\n\n\n

Use of grooved knives<\/h2>\n\n\n\n

In the case of slitter rewinders, you will mainly find shear cutting systems. Depending on the cutting width, these slitters have a knife shaft at the top and bottom, on which the knives are fixed with the proven DIENES solutions. If the cutting width allows it, knife holders and bottom knife motors are also used. <\/p>\n\n\n\n

A cutting tool mounted on the upper shaft is called an upper knife socket. The knives on the lower shaft, on the other hand, the lower knives are called grooved knives and have a cutting edge with relief grinding. On the lower cutter head, intermediate rings can also be used for format adjustment. Changes in the cutting width then require a change in the shaft equipment or a shaft exchange. Depending on the respective machine concept and, of course, also on the minimum cutting width to be achieved, different types of locking can be considered.<\/p>\n<\/div>\n\n\n\n
