Estimating the term…
To provide intimate contact between a sinter body holding a drawing die in ontact with a die support carrier, so that the setting will fit into a cup-shaped die holder, the carrier is a disk element having a base plate from which a stub leg, preferably in frusto-conical form, extends, defining a reentrant surface, the wider portion of which is spaced from the base plate, with a seating surface extending therefrom for the die, and the sinter body surrounding the die, extending into the reentrant surface defined by the conical projection of the stub leg from the base plate, and extending beyond the die, and fitting in the die holder, the setting being inserted in the die holder with the sinter body against the bottom of the cup-shaped die holder to accept compressive forces upon drawing of wire in the direction from the base plate through the diamond and then through the sinter holder, that is, reversed with respect to the customary direction, so that the sinter body will be placed under compression and in intimate direct contact with the die holder for efficient heat and force transfer.
Diamond drawing die and die setting combination adapted for insertion in a separate die holder (5), the die holder being cup-shaped and having upstanding inner wall portion, an open end and a bottom wall;
