Klopp shaper rocker gear -  this was formed as a single unit integral with the main bearing of the machine (the column bush)

Speed-change gearbox models 625, 725  and 850. On all the larger machines, a high-pressure pump delivered oil not only to the gearbox but also the rocker gear,, rocker arm and slideways

Underside of the ram from one of the larger Klopp shapers - light to reduce the effect of its mass at higher stroke rates yet at the same time well braced  for strength by internal ribbing

Rocker arm: the unit used to convert rotary motion into the rectilinear alternating movement necessary to drive the ram
