Image shows (right) an etching machine that puts the name etc. on to the blades. The blades fall down the chute at the back of the machine and into the troughs of nutralising solution that stops the effect of the acid.

The employee (left) is carrying a loaded spinning frame to the centrifugal dryers which dry the baldes after etching and after grinding.
