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.
