An apparatus for manufacturing a cable bolt includes a rotatably driven pay-out reel (20) for paying out a cable (1) coiled in use about the pay-out reel (20). An upstream accumulator (40) is located downstream of the pay-out reel (20) for accumulating cable (1) advanced from the pay-out reel (20). A bulb forming device (80) is located downstream of the upstream accumulator (40), for forming a bulb (2) in cable (1) advanced from the upstream accumulator (40). A cable drive (60) is located downstream of the upstream accumulator (40), for advancing cable (1) through the bulb forming device (80). The pay-out reel (20) is configured to rotate at least substantially continuously whilst the cable drive (60) is configured to advance the cable (1) after formation of each bulb (2) to a position for formation of a subsequent bulb (2) in the cable. The cable drive (60) stops a central portion (1b) of the cable downstream of the upstream accumulator (40) for formation of the subsequent bulb (2), the upstream accumulator accumulating or decumulating an upstream portion (1a) of the cable (1) as required throughout operation of the apparatus to allow at least substantially continuous rotation of the pay-out reel (20) whilst the central portion (1b) of the cable (1) is stationary.
