Apparatus for making clay ware handles has a die (1) movable between closed and open positions, in the closed position having a cavity (2) defining the shape of the handle. The cavity (2) has an inlet end (3) and an outlet end (4). The apparatus includes means (5) for injecting clay under pressure into the inlet end (3) and pressure control means (7) at the outlet end (4). The clay acts on the pressure control means (7), which controls the pressure of the clay in the cavity (2) and shuts off the clay injection means (5) when the pressure of the clay in the cavity reaches a threshold value. The pressure control means (7) ensures that the cavity (2) is full of clay at a sufficient level of plasticization, so that there are no voids in the handle. |
