Claim:
1. A device for cooling sheets of glass by jets of air emitted by at least one nozzle in a form of a pipe, comprising: a box supplying the at least one nozzle with air, wherein airflow ejected via an ejection orifice of the at least one nozzle passes successively through a conical part, of which an internal section is reduced in a flow direction, and then through a cylindrical part comprising the ejection orifice, of which an internal section corresponds to a smallest internal section of the conical part, and to the internal section of the ejection orifice and the airflow ejected via the ejection orifice is configured to blow air on the sheets of glass; and a roller bed conveying the sheets of glass, an axis of the ejection orifice passing between two rollers of the roller bed, wherein the cylindrical part of the at least one nozzle having a length which is greater than 6 times the diameter of the ejection orifice, wherein the at least one nozzle further comprises an additional tubular part located between a large base of the conical part and the box, wherein the internal section of the additional tubular part is equal to a largest internal section of the conical part and wherein the additional tubular part is non-linear.
