    摘要: Process for bending glass sheets, particularly in pairs, in which the glass sheets undergo a pre-bending under the effect of gravity in a horizontal position on a concave annular bending ring (3) whose profile corresponds to the desired final profile of the glass sheets, until the edges of the glass plates are applied entirely to the bending block (3). A monolithic convex bending block (31) is then applied over the whole surface and acts from above on the glass sheets (21). The inner part of the sheets then undergoes supplementary bending which gives it the desired final shape, the glass sheets being pressed by suction, against the monolithic convex bending block, at the edge of the monolithic convex bending block (11).

    摘要: In the manufacture of bent or curved car glass plates or panes with more markedly bent areas, the latter are additionally locally heated with acetylene--oxygen, or acetylene--air, flames. An apparatus suitable for this includes a continuous furnace (1) and a bending station (3) with a bending mold (41) positioned above the conveying plane of the glass plates (9), as well as a ring mold (45) which serves as a countermold and a conveying ring and which is located on a movable carriage (44). In the areas of more marked bending below the ring mold (45) are provided burner tubes (42), which are supplied via flexible hoses with the acetylene gas and the combustion air or oxygen. Alternatively, the plates are locally heated in a transition zone (7) located between the furnace and the bending station by a gas burner (8), and thereafter pressed in the bending station by an upper bending mold (14) and a lower ring mold (16).

    摘要: Glass plates are bent by discharging a glass plate from a suction plate onto a concave circumferential bending ring. Within the furnace (1) the glass plate is gripped by the suction plate (27) and is moved with the latter out of the furnace (1) into a combined bending and tempering station (10) and is discharged there onto the circumferential bending ring (19) located between two blowing boxes (11,13). Immediately following the discharge of the flass plate onto the circumferential bending ring (19), the suction plate (27) moves back to its starting position and the glass plate is tempered in this position.

    摘要: A method and installations for curving sheets of glass. The sheets of glass (9) are heated to the curving temperature in a horizontal position in a continuous furnace (1) and are pressed in a curving station (4) which is adjacent to the continuous furnace (1) by means of an annular frame against a solid surface curving form (40). During the pressing between the annular frame and the solid surface curving form (40), the sheets of glass (9) are pressed against said solid surface curving form (40), in the area located inside the annular frame, by the static pressure of a hot gas under pressure, with the static pressure of the gas being produced in a chamber (32) whose upper surface (33) is defined by the annular frame and is closed by the sheet of glass (9) applied in a sealed manner against said annular frame.

    摘要: A device for pressing and bending glass panes comprises an upper, solid-faced bending mold and a lower frame-shaped mold. The lower frame mold is mounted horizontally traversable and serves at the same time as a support ring for transferring the bent glass pane into a cooling station. The frame-shaped mold is provided with an electrical heating resistor. In addition, a temperature sensor is disposed in the frame-shaped mold. The temperature of the frame-shaped mold can be regulated to a predetermined temperature by way of a power regulator, which is governed by the temperature sensor.

    摘要: A production installation for the contact toughening of glass sheets comprises a horizontal furnace for heating the glass sheets, a press containing two liquid-cooled pressing plates, a feed apparatus for transferring the heated glass sheets into the press and a removal apparatus for removing the toughened glass sheets out of the press. To the lower pressing plate, a solids-transmitted sound pick-up is coupled which, if a glass sheet breaks in the press, supplies an electrical signal. From this signal, after suitable processing of the signal, the control device is triggered, and as a result thereof interrupts the process sequence.

    摘要: A continuous furnace (straight-through furnace) for heating glass panes to their curving and/or toughening temperature is constructed as a circular furnace and comprises an annular, horizontal hot gas support bed (3). On this annular hot gas support bed (3) the glass panes are carried, each by means of a template (56) of heat-resistant metal plate, also floating on the hot gas support bed (3), in a circuit from the feed station (6) to the discharge station (7). The templates (56) are each mounted on the arms (17) of a star-type turntable (16) concentrically to the support bed (3). At the discharge station (7) the glass panes, heated to bending and/or toughening temperature, are removed from the furnace by means of a radially traversable suction plate (42) and transferred into a bending and/or toughening device disposed laterally alongside the furnace.

    摘要: In an installation for bending glass panes, the glass panes are heated to bending temperature in a horizontal once-through furnace. At the end of the once-through furnace, they are taken over by an endless conveyor belt and are conveyed by this conveyor belt into the bending station, where they are bent together with the conveyor belt. The bent glass pane is conveyed of the conveyor belt into the succeeding cooling or tempering station. In order to support the bent glass pane over the largest possible area, an upper deflector roll for the conveyor belt, disposed at the exit end from the bending station, has a form corresponding to the transverse bend of the glass pane. A lower deflector roll, following the upper deflector roll, has a form complementary to the form of the upper deflector roll. In this way the relative changes in length of the conveyor belt caused by the upper deflector roll are compensated.
