A sealing machine and method for controlling a sealing machine Includes the following steps: placing capped containers provided with a seal on plates, rotating the plates, pressing the seal against the cap of the container and fastening said seal using a sealing head. The step of rotating the plates is performed by rotating each plate independently of the other plates. The method further includes: detecting at least one parameter associated with the rotation of a plate and/or with a compression load between each sealing head and the seal, and comparing the value of the detected parameter with a reference range.

A capping head includes a body centered on a center axis, a cam follower configured to roll on an outer peripheral surface of a cone cam, a forming roller configured to move in a radial direction as the cam follower moves in the radial direction, and a biasing member configured to bias the cam follower and the forming roller toward a radially inner side, a plurality of the forming rollers include a plurality of thread forming rollers, and at least one tuck under forming roller, and the body has a body recess portion depressed downward from an upper surface of the body and configured to accommodate at least a lower end portion of the cone cam.
