ABSTRACT:
The present apparatus applies force along a line or to a surface through one or more linear or rather longitudinal, elastically expandable or deformable members. The expansion of the elongated member, such as an elastic, reinforced hose or membrane, is transmitted to the tool proper, for example, a strip steel knife or a clamping device, along the entire length of the tool, whereby a linear force application is achieved. Several of such members may be arranged in parallel to obtain substantially a surface area force application. The force application member may also be curved for applying the force, such as a cutting force to an equally curved tool such as a strip steel knife. The force application member is returned to its starting position after a work stroke is completed. The work stroke is performed by expanding the member with the aid of a medium under pressure. The return is accomplished by a spring force or by a similar expansion member.
