<p>The machine comprises operating units (18, 18') placed above, below and laterally to the rotary table. The control of the advances of the operating units with vertical axes comes about by levers (1, 1'), controlled by disks (2,2') in turn driven by a cam (15) having opposite profiles so as to control said disks (2, 2') in the opposite direction. The extent of the advance of operating units (18, 18') is varied individually by moving fulcrums (4, 4') of said levers (1,1'). <IMAGE></p> |
