<p>A force is applied to a tool, such as a strip steel knife, a counter-holder or the like, through a linear pneumatic drive including a pressure expandable hose closed at its ends which expands in a given direction. The hose, a reaction plate and a force output plate extend in parallel to each other and through at least one modular reaction bail form a modular drive unit. Force transmission lever means extending at an angle to said given direction are operatively interposed between the force output plate and the tool for applying the force in a plane extending at an angle or in parallel to said given direction, whereby the compactness and versatility of a cutting apparatus employing such modular drive units is enhanced. These modular drive units, possibly in combination with modular drive units which apply the force in the direction of hose expansion, are adjustably supported by an exchangeable coordinate support frame structure to form a three-dimensionally effective stamping or cutting machine in which the cutting knives may cooperate with foaming molds, counter-holders or the like and wherein the linear pneumatic drives are supported in at least one plane, possibly in three planes formed by the coordinate support frame structure.</p> |
