Abstract
Abstract The disclosure is directed to a die set in which at least one of the die members of the set includes a nest block composed of a semirigid, flexible material. Such die member comprises a support block for receipt of said nest block together with end blocks for restraining the nest block therebetween. The cooperating die member of the die set has a nest which permits entry of the nest block such that the shape of the nest of the nest block may be controlled jointly by the interaction between the nest block and the nest of the cooperating die member and the effects of an object placed therebetween. In other configurations of the die set both die members may include a nest block of semirigid, flexible material. In either of the embodiments the nest may be of uniform nest configuration such as a V-notch or an arcuate portion, or a composite configuration having an arcuate portion and straight sides. Raised portions may be introduced along the length of the nest in order to place greater force upon particular portions of the object placed in the die set.
