Abstract (en)
[origin: EP0754506A2] In the cornice brake are present rows of punches, dies and modular units constituting extensions of punches and clamping jaws for said punches and extensions. The compressed air system is characterized in that: clamping of the jaws takes place through bolts put in tension by means of compressed air cylinder actuators; supply of the compressed air cylinders of the actuators takes place through ducts made inside the body of the jaws and/or said extensions and through tubes running between jaws and/or said extensions of each side-by-side pair; and the tubes running between said extensions are metal tubes with straight horizontal axis partly running between extensions of each side-by-side pair and partly inserted in cavities made in the sides of said extensions with the capability of airtight running within said cavities. <IMAGE>
