  • Process and apparatus for coating glass containers and coated glass container
    Patent number: 6503328
    Abstract: Glass containers are taken to a high temperature in an annealing furnace and removed from the annealing furnace belt by grips of a gripping device. The gripping device is then moved by a handling device first vertically upwards, then horizontally above a fluidized bed and then downwards into the fluidized bed in order to coat the glass containers with a powder, it is then taken upwards out of the fluidized bed and finally moved horizontally over a conveyor belt. There, the glass containers are released from the gripping device and set down on the conveyor belt which takes the powder-coated glass containers through a second curing region in which the powder coating is cured to form a substantially duroplastic layer.

  • Process and device for coating glass containers and coated glass containers
    Patent number: 6329019
    Abstract: Glass containers (3) are taken to a high temperature in an annealing furnace (7) and removed from the annealing furnace belt (5) by grips (16) of a gripping device (12). The gripping device (12) is then moved by a handling device (13) first vertically upwards, then horizontally above a fluidized bed (18) and then downwards into the fluidized bed in order to coat the glass containers (3) with a powder; it is then taken upwards out of the fluidized bed (18) and finally moved horizontally over a conveyor belt (22). There, the glass containers (3) are released from the gripping device (12) and set down on the conveyor belt (22) which takes the powder-coated glass containers (3) through a second curing region (27) in which the powder is cured to form a substantially duroplastic layer.
