Abstract
A press is adapted for the press tool it is to operate, by means of at least one pad of force-transmitting material formed in situ on a surface adapted to transmit the forming force to the press tool. The pad is formed by locating a tool substitute in the space intended for the tool, defining at least one volume between the tool substitute and the said surface adapted to transmit the forming force with a sealing means and injecting the pad forming material in liquid state into the said volume to allow the same to harden there preferably under a force equivalent to that which will be used in forming a blank when the substitute tool is replaced by the press tool.
