摘要

A method of swaging is provided to mount an anchor member (14) on a solid shaft (12) to form a component of a yielding rock bolt The anchor member (14) is mounted on the shaft (10) and the assembly is placed in a swage press (10) having three or more swage press members (50) which are equiangularly disposed about the anchor member (14). The swage press members (50) are simultaneously applied to the anchor member (14) laterally to apply pressure so as to deform this anchor member (14) and the shaft (12).
