Abstract: Clamping device and method to temporarily clamp, in a mixing machine (11), a container (12) containing a fluid product, comprising two clamping elements (20, 21), opposite each other and able to clamp the container (12) in a determinate position. A movement mechanism (22), controlled by a control unit (24), is able to reciprocally move the clamping elements (20, 21) and impart thereto a clamping force (F) or clamping impulse, according to the actual height (L) of the container (12). The control unit (24) is also able to calculate, as a function of the clamping force (F), a relative clamping speed (v3), at which to move reciprocally the two clamping elements (20, 21) so as to clamp the container.

Abstract: An anti-rotation device for a gripping member of a mixing machine for fluid products contained in a closed container. The mixing machine comprises a fixed structure and the gripping member comprises a supporting structure rotary with respect to the fixed structure and on which two gripping elements are mounted, able to be selectively moved nearer to or farther from each other by means of a screw, in order to determine the temporary clamping of the container with respect to the supporting structure.
