Abstract

A housing is provided with a shearhead having an opening, a perforated shearfoil spans the opening and underneath the shearfoil are mounted shear blades the cutting edges of which contact the shearfoil. A drive is coupled with the blades for making the same move relative to the shearfoil; it has at least one flexural unit composed of a plurality of bilaminar flexural oscillators of ferro-electric ceramic material which are mechanically coupled so that they perform their movements in unison.
