Oven and process for manufacturing an envelope for use in a display tube |
摘要 |
The invention relates to an oven for sealing a panel to a funnel, thus forming an envelope suitable for use in a display tube, comprising a tunnel structure 9 and at least one mount for conveying an assembly of a panel and a funnel through the tunnel structure 9. The tunnel structure 9 is provided with a longitudinal slot 16A and the components of the mount for guiding the mount along and through the tunnel structure 9 are placed outside the tunnel structure. It is preferred that the components comprise a means, such as a pump or compressor 24, for flushing the interior of the assembly 22 with a fluid obtained from a source which is substantially separated from the gas(es) circulating in the oven 1, e.g. from the surroundings of the oven 1.
