  • Patent number: 10870600
    Abstract: A bending tool for bending at least one glass pane by suction, includes a frame-like convex contact surface and a cover having a peripheral air guide plate that surrounds the contact surface at least in regions is described. The bending tool is suitable for generating a first, reduced pressure in a first pressure region between the air guide plate and the contact surface; a second reduced pressure in a second pressure region. The second pressure is less than the first pressure; and a third pressure in a third pressure region, wherein the third pressure is greater than the first pressure.

  • Patent number: 10662105
    Abstract: A device for heating objects and a method that has recourse to the device, particularly for heating and/or bending one or more glass panes positioned one on top of the other, covering each other. The device includes a furnace line, plural supports, particularly transport molds that transport and/or bend the objects, the objects being placed on the supports positioned on transport carriages, a drive device that progresses the transport carriages through the furnace line and plural heating elements provided above the objects in the furnace line. In the device the heating elements are positioned on the whole above the entire furnace line and the heating elements can be operated and regulated so as to form heating zones suited to dimensions of the objects.

  • Patent number: 9656537
    Abstract: A vehicle glazing is described. The vehicle glazing has at least one windowpane having a height from 900 mm to 1650 mm, a top upper edge, a side edge of a pillar, a body edge, and two rectangular surfaces A and B. The surface A has an extent of 800 mm*800 mm and the surface B has an extent of 1000 mm*700 mm. Surface A and surface B are centrally bounded by the lowest contact point of the at least one windowpane with the body edge horizontally with respect to the ground, and the lowest contact point and the point of the top upper edge at the shortest distance from the contact point form a Y0 axis and the points at the furthest distance with respect to the width of the windowpane form a Z0 axis.

  • Patent number: 9452662
    Abstract: A method for bending a sheet is described. The method includes the following steps: a) at least one sheet is inserted into a pre-bending ring with a movable bending ring holder, the at least one sheet is heated at least to an approximately softening temperature, and the at least one sheet is prebent in the pre-bending ring to 5% to 50% of a final edge bending, b) the pre-bent sheet is lifted out of the pre-bending ring by means of a suction device and is bent further, beyond a bending obtained in the pre-bending ring, c) the at least one sheet is laid down by means of the suction device in a final-bending ring on the movable bending ring holder and the at least one sheet is bent to a final bending, and d) the at least one sheet is cooled down in the final-bending ring and the at least one sheet is bent by means of the suction device to 100% to 130% of an overall final edge bending.

  • Patent number: 8964279
    Abstract: An electrode is produced on a rigid or flexible support substrate, including a grid network of very fine electrically-conductive lines with nodes and links, to produce a diffraction pattern, as much as possible in an arc shape, in the light transmitted and that results in an absence of high-level optical impacts. The grid network may in addition be produced without preferential direction with a number of three lines joining up at each node and/or with conductive sections extending in the shape of an arc or in wave form between the nodes.
