Abstract: A machine has an intermittently rotating table for holding parts to be worked on or assembled. Operating units (20, 21, 25) are actuable either simultaneously for all units or groups of units, or independently of one another. The operating units can be mounted vertically over or under the table and also laterally and can receive the rotary movement of a central wheel or independent motors. According to a preferred embodiment, the control of the feed is effected by the central shaft (4). During a work cycle, this shaft makes a vertical movement and transmits that movement to the operating units (20, 21) by radial linear cams (16, 17, etc.), i.e., feed and return occur during a single movement of the shaft (4), for example, downward. During idle time, i.e.
