Apparatus for moulding a generally solid block or like component having a tool engaging recess comprising:
- a mould box for receiving material and for moulding said material to form said block;
- means for forming a recess in said material in said mould during formation of said block, said recess forming means being movable relative to said mould box;
- means relative to said mould box for tamping said material in said mould during formation of said block said tamping means being movable relative to said mould box and said recess forming means;
- and
- means for moving said tamping means relative to said mould box to tamp said material in said mould box,
- whereby movement of said tamping means in successive strokes to tamp said material in said mould box is coordinated with said recess forming means so that said recess forming means enters said material in successive strokes in sequence with said strokes of said tamping means.
