  • Oven and process for manufacturing an envelope for use in a display tube
    Patent number: 6527547
    Abstract: 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.
