Abstract: A stepped cone draw block disclosed has intermediate sheaves which each include a pair of plate-like annular sheave members with peripheral flanges between which a ceramic ring for drawing a wire is clamped. Side surfaces of the sheave members of each intermediate sheave face away from each other along an axis of a shaft on which the draw block is mounted and axially facing surfaces of these sheave members are bolted in engagement with each other midway between the side surfaces. One sheave member of each intermediate sheave has a central opening sized to receive and mount the sheave on the shaft with a shaft key received within a keyway of the opening to provide coupling to the shaft, while the other sheave member has an opening slightly larger than the shaft and a groove aligned with but slightly larger than the keyway so as to facilitate mounting of the sheave.
