An automatic production machine having a headpiece that is adapted to hold a workpiece and/or a work tool and a support for carrying the headpiece. The headpiece and the support are self-contained units which are independent of each other. The support has a mount for supporting the headpiece for pivotal movement with respect to the support about a transverse pivot axis and a drive for pivoting the headpiece when the same is pivotably supported by the support. The headpiece has a mount capable of being pivotably received by the mount of the support and at least one extension which, when the headpiece is pivotably supported by the support, extends into the support and coacts with the drive such that upon actuation of the latter, the headpiece is pivoted about the transverse pivot axis. The connection between the mount on the headpiece and the mount on the support as well as the connection between the extension of the headpiece and the drive of the support are detachable connections and form the sole structural connections between the headpiece and the support. Consequently, the support may be used in conjunction with any one of a plurality of headpieces each of which may, by establishing and breaking the two connections, as required, be interchanged for another headpiece.
