<p>A table comprises two table parts 1 and 2 for movement along guides 3, 4. The table part 1 is reciprocable by a piston rod 5 and is connected to the table part 2 by a linkage 6, 7, 8 and 9 to reciprocate the table part 2 by opposite but equal increments. An electrode mounted between the parts simultaneously forms mirror image impressions in workpieces fixed to the respective table parts. <IMAGE></p> |
