Abstract
A method of moulding concrete ties in a series of open ended multi-cavity moulds which are arranged to have corresponding cavities aligned, and comprises positioning reinforcing wires in the aligned cavities and straining the wires, positioning spacers between adjacent ends of adjacent moulds and between the wires, filling the moulds with wet concrete to surround the wires, removing the spacers after the concrete has set and releasing the tension on the wires, severing the wires between adjacent moulds, coupling a tilt frame to one side of a mould frame and a base frame, the tilt frame comprising a pivot having a longitudinal axis, and lifting the other side of the mould frame to thereby pivot the mould frame about the longitudinal axis, lowering the mould frame to invert it and discharging the ties from the inverted moulds.
