Application

	The die holder is used for single and multi-part die inserts. The parts of the holder are each clamped by means of a Feuerbacher tensioning key and a shim. Both keys are provided with a block insert to prevent longitudinal displacement. When exchanging the die only the die inserts must be replaced. The base holders remain in the hammer. The offset in the die can be adjusted by using thin metal shims. In this case the inserts themselves are clamped using conventional wedges.

Alternative arrangements

	As an alternative to using a shim, the holder can also, on one side, be clamped directly against the ram or the anvil bed. The advantage of this possibility is the greater contact area of the impact faces. Thereby the tendency for tiling is reduced considerably.
