摘要
A die head for a roll imprinting machine for the imprinting of edges of grooves preformed in a valve core for a rotary valve for use in a power steering gear, the die head supporting a circular cluster of radially disposed rolling die holders, each die holder carrying at an inner end an arcuate imprinting die and being mounted for partial rotation on a transversely extending axle, partial rotation of all the die holders being effected synchronously, by action on each die holder at a position on the die holder more remote from the inner end of the die holder than the position of the axle and valve core locater arranged to locate and hold the valve core at the center of the cluster for roll imprinting by the imprinting dies in a synchronous relationship.
