| 摘要 |
A process for joining objects, such as wooden boards, by means of a cement adapted to be hardened in an electric high-frequency field between a pair of electrodes, wherein the section of the objects situated between the electrodes is sealed off by means of a suitable layer of resilient material pressed against the surfaces of the objects to prevent steam and ionized gases from escaping from the objects to the surrounding space, thereby permitting a substantial increase of the electric energy applied without risk of spark discharge between the electrodes. The invention also provides a device for performing this process, comprising a pair of electrodes provided with a layer of such resilient material. |
