Abstract
In shears for rod-form material, especially in connection to roll trains, the problem exists of a space-saving construction, especially in the sidewise direction, in view of the multiple arrangements, as well as increased safety (reliability) of operation for the high-pressure hydraulic system of the cutting drive. The shear provided with two knife holders (MT1, MT2) and a fluid drive element (ZK) as well as a respective pressure feeding device (DS), is so designed, for this purpose, that the pressure work chambers (DA1, DA2) of the drive element, such as a double-acting cylinder-piston arrangement, and the elements carrying pressure fluid (high-pressure pumps, etc.) of the pressure feeding device (DS) are designed to be movable in common with a knife holder (MT1) which is movable in relation to the machine frame or a conduction (SF) of material to be cut, and preferably fixed in space with this latter (MT1).
