1. A method for rotating rotationally symmetrical containers at a predetermined first area along a conveying surface comprising the steps of:
- (a) limiting the conveying surface laterally in the first area by at least two railings the distance between the railings being limited to about 1.2 to 1.6 times the diameter of the container;
(b) transporting the containers under backup pressure;
(c) arranging one of two consecutive containers stable against one of the at least two railings and the other stable against the other of the at least two railings in the direction of conveyance after the first area by reducing the distance between said at least two railings at an angle β
of the lateral railings to each other of about 30°
to 100°
to about somewhat more than the diameter of the containers and arranging the at least two railings substantially symmetrical to the midline of the conveying surface;
thereby rotating said containers.

Abstract
Rotationally symmetrical containers (10) are transported under backup pressure on a conveying surface (12) limited laterally by railings (14). For rotating the containers (10) at a predetermined site along the conveying surface (12), one of two consecutive containers (10) is arranged stable against one railing (14) and the other stable against the other railing (14) in the direction of conveyance after the site at which the containers are to rotate.

2. An apparatus for rotating rotationally symmetrical containers comprising:
-
(a) a conveying surface with a predetermined first area where the containers are to rotate; (b) at least two railings limiting the conveying surface laterally, the distance between the railings in the first area being limited to about 1.2 to 1.6 times the diameter of the container; (c) means for transporting the containers under backup pressure on the conveying surface; and (d) means for the stable arrangement of one of two consecutive containers at one of the at least two railings and of the other container at the other of the at least two railings, the stable arrangement means following the first area in the direction of conveyance and comprising said distance between said at least two railings substantially symmetrically reducing at an angle β
of said at least two railings to each other of about 30°
to 100°
to about somewhat more than the diameter of the containers and arranging said at least two railings substantially symmetrical to the midline of the conveying surface. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)

12. An apparatus for rotating rotationally symmetrical containers comprising:
-
(a) a conveying surface with a predetermined first area where the containers are to rotate; (b) at least two railings limiting the conveying surface laterally the distance between the two railings in the first area being limited to about 1.2 to 1.6 times the diameter of the container and wherein the distance between the railings is constant through the first area; (c) means for transporting the containers under backup pressure on the conveying surface; (d) means for stable arrangement of one of two consecutive containers at one of the at least two railings and of the other container at the other of the at least two railings, the stable arrangement means following the first area in the direction of conveyance and comprising said distance between said at least two railings substantially symmetrically reducing to an angle β
of said at least two railing to each other of about 30°
to 100°
to about somewhat more than the diameter of the containers. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
