ABSTRACT:
A double-rotor shear used to cut materials in strip form has opposing blades arranged to rotate in opposite directions with respect to two parallel axes. The cutting edge of each of the blades is rectilinear and situated in a plane passing through the corresponding axis of rotation at an angle with respect to the axis. At all times during operation the two cutting edges are disposed symmetrically with respect to the plane passing through a line equidistant from the two axes of rotation, which plane is normal to the plane defined by these axes.
