PROBLEM TO BE SOLVED: To improve ability of a rotary capper and to prevent dust from being generated in the capper for performing capping while pressure is applied. SOLUTION: On a rotating body rotated and driven by means of a motor, a plurality of container grips and capping heads respectively above them are provided at equal intervals in the circumferential direction. Spindles provided with the capping heads are respectively connected with servo motors 32 working independently from the above described motor and are rotated. Cam followers are respectively fitted on each of the spindles and elevation and lowering is performed by hooking these cam followers in cam channels of fixed cylindrical cams and moving them. A speed detecting means 42 and an angle detecting means 44 are provided on the rotating body and by these detected signals, a control means 46 controls rotation of each servo motor 32. Rotation can be started before the capping head reaches the lowest position and it can cope with speeding-up.
