In apparatus for slush moulding a boot a mould 3 is attached to a carrier 2 pivotally mounted on a trolley 1 for movement along a track 6 by means of conveyer chain 7, As the mould 3 is advanced in the direction of the arrow 34 as shoulder 35 on the trolley 1 closes a switch 36 on a filling gun carrier 26 to actuate a piston within a cylinder 33 to lower an elevator 27 carrying a filling gun 28 connected to a supply of liquid moulding material. When a switch 38 on the elevator 27 is closed by engagement with a flange 39 on the trolley 1 the downward movement of the elevator 27 is stopped and the filling gun 28 is actuated to fill the mould 3. When the level of liquid in the mould 3 rises sufficiently a control float 40 is lifted to discontinue the supply to the gun 28 and the piston in the cylinder 33 is actuated to raise the elevator 27 and remove the gun from the mould. Specification 841,754 is referred to.
