In a driving system for the cross closing jaw (16) of a continually operating flow packing machine it is customary that the drive motor (30) for the vertical movements of the jaw is mounted on the sledge (8) reciprocating the jaws along the conveying path. According to the invention, the motor (30) should not participate in these movements as it is mounted in a stationary manner for driving a longitudinally extending shaft (20) which cooperates with a drive bushing mounted on the sledge so as to be slidable along the shaft (20) and operating to control the said vertical movements. |
