Spacers from DIENES
From a manufacturing point of view, very high demands must be placed on spacers in particular the very tight tolerances. As a cutting expert, we can help you here, because the cutting width does not depend solely on how the bottom knives are arranged on the shaft. The web tension, the concentricity and the way in which the bottom knives are set play a decisive role. Whether paper, cardboard or paperboard, labels or adhesive tape, aluminum, film, foil, plastic or nonwoven and textile, we have a solution for them from a total thickness of 0.1 mm. As standard materials we work with chrome alloyed tool steels (1.5% Cr).
Spacers are used in cutting processes with fully loaded shafts in shear and roller shear cutting and serve here on the one hand as spacers and on the other hand to support the web.
The accuracy of the cutting widths, in turn, depends to a large extent on the thickness tolerances achieved for the spacers in conjunction with the bottom knife or roller shear knife, or the fully loaded shafts. Cutting widths can be achieved in various ways. For small widths, the distance is determined by the width of the bottom knives, so no spacer ring is used. For larger cutting widths, spacers are used. Bottom knives can also be used as spacers if necessary. The spacer therefore has no significance from a cutting point of view, but is very important for the change of cutting width.
Top knives can also be adjusted to cutting widths with the aid of spacers. Provided that the top knife hubs have the appropriate tolerances, a more favorable fixed tension of the top knives can be achieved.
