Apparatus and method for manufacturing a rock bolt

摘要

An apparatus for manufacturing a cable bolt from a cable (1) includes first and second clamps (2, 3) adapted to releasably clamp the cable (1) with the cable (1) extending along the longitudinal axis (4) of the apparatus. A first cable displacement device (12) longitudinally displaces the first clamp (2) relative to the second clamp (3) along the longitudinal axis (4). A first clamp rotation device (14) rotates the first clamp (2) relative to the second clamp (3) about the longitudinal axis (4). The apparatus also has a second clamp displacement device (19) for simultaneously longitudinally displacing the first and second clamps (2, 3) along the longitudinal axis (4).
