Abstract
The invention relates to the production of composite insulators consisting of a shank in the form of a bar or a tube, which is provided with a covering and which comprises plate-like screens which are distanced from each other. The covering and the screens are made of an elastomer material with high insulating qualities. As a result, the number, distance, form and size of the screens can vary from insulator to insulator. According to the invention, at least one injection mould () for injecting a screen () is arranged downstream from a device which is used to provide the shank () with a covering. The injection mould can be advanced in order to inject a screen upon the shank and opened in order to unmould said screen. An advancing device is also provided in order to displace () the shank () or the screen mould. Each time the shank () or the screen mould is displaced, the position of the latter with respect to the shank enables a subsequent screen to be injected.
