A method for sorting hollow bodies that are closed on one side, having a front-side opening, a base surface opposite said opening, and a lateral surface extending between the base surface and the opening, comprising the steps of: - conveying the hollow bodies in a single row in a conveying direction along a sorting section having an inlet and an outlet, and a guide open on one side, which is adapted for conveying the hollow bodies in a single row in a conveying direction along the sorting section, said guide comprising a lower guide, an upper guide opposite the lower guide, a lateral guide disposed between the upper and the lower guide, and an outlet opposite the lateral guide for ejecting hollow bodies that have been separated out, wherein the hollow bodies in the sorting section point in the direction of the lower guide either with the base surface or with the front-side opening, - guiding a first fluid flow through the upper guide and guiding a second fluid flow through the lower guide, or guiding the first fluid flow through the lower guide and guiding the second fluid flow through the upper guide, - aligning the first fluid flow in the direction of the lateral guide in such a manner that the first fluid flow either impinges upon the base surface of each hollow body from the outside, or impinges through the front-side opening upon a part of the lateral surface of each hollow body that abuts against the lateral guide, - aligning a second fluid flow in the direction of the outlet in such a manner that the second fluid flow either impinges upon the base surface of each hollow body from the outside, or impinges through the front-side opening upon a part of the lateral surface of each hollow body that points in the direction of the outlet, wherein - the first and/or second fluid flow (9b, 10b) has a vector in the conveying direction, and - the aligning of the first and/or the second fluid flow (9b, 10b) is accomplished with the aid of a plurality of nozzles disposed along the sorting section on the upper and lower guides. - conveying the hollow bodies in a single row in a conveying direction along a sorting section having an inlet and an outlet, and a guide open on one side, which is adapted for conveying the hollow bodies in a single row in a conveying direction along the sorting section, said guide comprising a lower guide, an upper guide opposite the lower guide, a lateral guide disposed between the upper and the lower guide, and an outlet opposite the lateral guide for ejecting hollow bodies that have been separated out, wherein the hollow bodies in the sorting section point in the direction of the lower guide either with the base surface or with the front-side opening, - guiding a first fluid flow through the upper guide and guiding a second fluid flow through the lower guide, or guiding the first fluid flow through the lower guide and guiding the second fluid flow through the upper guide, - aligning the first fluid flow in the direction of the lateral guide in such a manner that the first fluid flow either impinges upon the base surface of each hollow body from the outside, or impinges through the front-side opening upon a part of the lateral surface of each hollow body that abuts against the lateral guide, - aligning a second fluid flow in the direction of the outlet in such a manner that the second fluid flow either impinges upon the base surface of each hollow body from the outside, or impinges through the front-side opening upon a part of the lateral surface of each hollow body that points in the direction of the outlet, wherein - the first and/or second fluid flow (9b, 10b) has a vector in the conveying direction, and - the aligning of the first and/or the second fluid flow (9b, 10b) is accomplished with the aid of a plurality of nozzles disposed along the sorting section on the upper and lower guides. - the first and/or second fluid flow (9b, 10b) has a vector in the conveying direction, and - the aligning of the first and/or the second fluid flow (9b, 10b) is accomplished with the aid of a plurality of nozzles disposed along the sorting section on the upper and lower guides.
