    摘要： The invention relates to a device for cooling glass sheets using jets of air emitted by at least one pipe-shaped nozzle, including a casing (4) supplying air to said nozzle. The air flow ejected via the ejection opening (3) of the nozzle consecutively passes through a tapered portion (1), the inner cross-section of which decreases in the direction of flow, then through a cylindrical portion (2) including the ejection opening, wherein the inner cross-section of said cylindrical portion corresponds to the smallest cross-section of the tapered portion and to the inner cross-section of the ejection opening. The length of the cylindrical portion of the nozzle is greater than six times the diameter of the ejection opening. Said device provides high heat exchange during the cooling of glass sheets, thus making it possible to increase the reinforcing effect on the glass and/or to reduce the power of the fans used for conveying the air through the nozzles.

    摘要： The invention relates to a device for bending sheets of glass running between a bed of upper rolls and a bed of lower rolls forming a shaping bed that pinches the sheets as they run, said shaping bed being disposed in a path having a curved profile in the running direction of the sheets of glass, said shaping bed comprising at least one roll of what is known as the rod/sheath type comprising a fixed metal rod preformed in a curved profile lengthwise and a flexible sheath that is able to rotate about said rod, said sheath being rotated about said rod. The roll of the rod/sheath type may comprise a metal rod preformed in a curved profile lengthwise and a flexible sheath that is able to rotate about the rod, said sheath comprising a first envelope made of a polymer material and a second envelope made of a flexible metal material disposed around the first envelope, the first and the second envelope rotating together as one.
