An apparatus for positioning a reinforcing tendon into a drill hole formed rock face including a body portion having a bore extending axially therethrough. The bore has a dimension selected to allow limited sliding movement of the tendon therethrough and includes a portion which tapers inwardly from a forward outfeed end towards a rearward or infeed end. A wedging member is movably provided in the bore. Movement of the wedging member towards the rearward end of the body results in its frictional engagement with the tendon to restrict its withdrawal from the body relative to the infeed end, whereas movement of the wedging member relative to the bore towards the outfeed end results in its disengagement from the tendon allowing it to be repositioned forwardly relative to the body. A drive is further provided to reciprocally move the body relative to the rock face.
