embossing formations 14 the internal cam force action on the inner tool parts 11 a is forward of the embossing formations 12 the forces balance out to provide a final embossed pattern of consistent depth formations over the entire zone of the embossed pattern 50 next actuator 21 returns to its start position arrow e permitting the arms 13 of the external toiling to flex outwardly to their normal position in so doing tooling parts 13 a disengage from embossing engagement with the container 1 external surface at this stage in the procedure the situation is as shown in fig1 14 a the next stage in the procedure is for the internal mandrel to collapse moving tooling parts 11 a out of abutment with the internal wall of the cylinder 1 at this stage in the procedure the situation is as shown in fig1 15 a finally the tooling table 6 is retracted away from the rotatable table 3 withdrawing the tooling 10 from the container at this stage in the procedure the situation is as shown in fig1 16 a in the embodiment described the movement of the tools to effect embossing is translational only it is however feasible to utilize rotational external internal embossing tooling as is known generally in the prior art.
