Abstract: The invention relates to an assembly machine having a frame, an upper plate vertically displaceable, a table, an annular transfer plate, a cam-shaft and a driving device for said cam-shaft. Said machine comprises working units of three kinds, the one fixed onto the upper plate and the others fixed onto the table either inside or outside of the transfer plate. All working units fixed to the upper plate and the ones fixed to the table inside the transfer plate are controlled by cams carried by the cam-shaft and corresponding mechanical linkages passing through a control opening provided in the table of the frame.
