DEVICE FOR UPRIGHTING CONTAINERS FROM A POSITION WHICH THEIR AXIS HORIZONTAL TO A POSITION WITH THEIR AXIS VERTICAL A device for uprighting containers from a position with their axis horizontal to a position with their axis vertical comprises a circular plate (3) fixed to the end of a shaft (5) of horizontal axis by means of a support structure (4) arranged to undergo stepwise rotations of 180.degree. in synchronism with a container feed line (1); two parallel shafts (14, 15) symmetrically arranged about a diameter of the plate (3) and each carrying, at that end facing away from the plate, a receptacle (18) for seizing the containers, said shafts being connected mechanically such as to undergo equal rotations in the same direction, and carrying the receptacles (18) thereon with their axes mutually perpendicular; and a fixed positive-acting cam (25) within which there engages the end of a rocker arm (23) pivoted on the plate (3), its opposite end rotating one of the shafts (14 or 15) by means of a mechanism comprising a connecting rod-crank unit (21, 22).
