Abstract (en)
[origin: WO2020053127A1] The invention relates to a drawing die and the associated nib holder. The nib holder is construed such that at least 20% of the nib mantle surface remains exposed to the coolant during drawing in a limited number e.g. two, three up to twelve disjoint areas. In this way a sufficient cooling of the nib is guaranteed. The nib holder comprises a base plate with protruding clamps that hold the nib. The nib holder is made of a single piece of material. An associated method to insert the nib into the nib holder is also described.
