发明名称 A sealing arrangement for optodevice moulds
摘要 A mold arrangement for moulding an optodevice onto an optical ribbon fibre. The mould includes of a plurality of plates which are intended to be inserted between the movable top plate and the stationary bottom plate, or counterpressure plate, of a transfer moulding press, and includes an inlet channel, primary and secondary runners and an optodevice moulding cavity formed when two plates are brought together and through which the ribbon fibre extends. According to the invention, the mould cavity is provided with an outwardly projecting part at the ribbon-inlet end of the optodevice, and a seal in the form of a rubber sleeve or a sleeve of some similar material disposed around the ribbon and positioned in the mould cavity so that one end of the sleeve will completely fill the outwardly projecting part and so that the other end of the sleeve extends into the mould cavity. The seal in the moulded optodevice extends out from the optodevice around the ribbon fibre.
