    摘要: A device for tempering of a glazing by contact has two cooled compression plates and a device for cooling the peripheral surface of the glazing by air jets. The device intended to cool peripheral surfaces of the glazing consists of parallelepipedic blowing ramps placed between cooling and compression plates and in which are provided slots for the cooling air jets directed toward the peripheral surface of the glazing, and exhaust openings placed between the slots. The slots have a diameter at least equal to 1 mm and at most equal to the thickness of the glazings, and the exhaust openings having a cross section which is at least three times that of slots. The dimensions of the cooling and compression plates, as well as arrangement and/or width (B) of the ramps are such that a distance (A) between the orifices of outlet slots and peripheral surface of glazing which is opposite to it is at least two times and at most six times the diameter of the slots.

    摘要: An apparatus for bending and tempering glass plates has a horizontal roller furnace (3) and a press bending station with two water-cooled bending molds (6,7) through whose contact the glass plates are tempered immediately following bending. At the outlet from the roller furnace (3), the glass plates (1) are taken over by a continuous flexible conveyor belt (10) and are conveyed by the latter into the bending station. During the press process the glass plate remains on the conveyor belt, which is interposed between the glass plate (1) and the lower bending mold (7). The conveyor belt (10) is made from a woven or knitted fabric of heat-resistant metal fibers and, in a direction at right angles to its surface, has a heat resistivity of 0.25.times.10.sup.-3 to 5.times.10.sup.-3 m.sup.2 .times.K.times.W.sup.-1.

    摘要: In a substantially horizontal conveyor or conveying heated glass sheets, a positioning device for aligning the sheets in a direction transverse to the conveying direction. It includes thrust rods advanced by the engagement of cam followers moving with the thrust rod on cams stationary with respect to the conveyor. Draw springs return the thrust rods to their initial position. The thrust rods are mounted on crosswise carriages, which are in turn mounted on carriages movable in the conveying direction and in synchronism with the glass sheets. The thrust rods are pivotally mounted on the crosswise carriages about horizontal axes, and so their distal ends can be displaced out of the plane of the glass sheets during the return movement of the carriage.

    摘要: Glass sheets are bent in stages into the final shape in a horizontal position in two successive bending stations. The glass sheets heated to bending temperature are laid on a fabric carrier arranged resiliently on a rigid support frame. The glass sheets are conveyed stepwise with the fabric carrier and the support frame through the bending system, and are bent together with the fabric carrier which adapts to the shape of the glass sheets.

    摘要: A method and device for the bending, on a frame, at least one glass sheet by gravity includes two bending steps. The glass sheets are first supported at their periphery along a first peripheral line by a rough bending device during the first step and along a second peripheral line by a definitive bending device during the second step. Transfer of the glass sheets from the first peripheral line to the second peripheral line is performed by positively and continuously regulating a position of at least one of the rough and definitive bending devices in reaction to forces generated on the at least one of the rough and definitive bending devices by contact with the glass sheet.

    摘要: In a method and apparatus for bending glass plates, the glass plates are heated in a horizontal position in a continuous furnace (1) to the bending temperature and in a following bending chamber (5) are pressed by an upwardly flowing hot gas stream against a convex bending mold (7) positioned above the conveying plane. The bent glass plates (3') are placed on a displaceable shaping ring (13) and transferred with the latter into a following cooling station (16). The glass plates (3) are raised from the conveying roller train (2) of the continuous furnace (1) by a suction plate (3) are positioned relative to the transfer ring (28) on the latter. With the aid of the transfer ring (28) the glass plates (3) are transferred into the bending chamber, where in the end position of the transfer ring (28) they assume the desired end position relative to the bending mold (7).

    摘要: A holding device for glazing panes heated in a horizontal position to a deformation temperature comprises a downwardly facing contact surface, to which the glazing pane is held by suction action. The contact surface is formed of a tensioned fabric of highly heat-resistant fibers. As the glazing panes are sucked on, the fabric yields and bulges upwards. The amount of the bulge of the fabric is dependent upon the tension in the fabric. By the bulging of the fabric the glazing pane undergoes a bending opposite to the succeeding bending of the glazing pane under the effect of its self-weight. This counter-bending compensates an undesired transverse bending during the later bending process.
