DEVICE FOR INJECTING A SOUL, IN PARTICULAR AN ELECTRIC LADDER.

摘要

A device for spraying the outside of a core, especially of an electric conductor, with a jacket having at least two layers or strips of different or differently coloured materials, which device has at least two separate supply channels for the plasticised materials and at least two outlet cross-sections for the plasticised materials, through which can pass the core to be sprayed, which outlet cross- sections can be connected, as desired, to the supply channels, via a distribution device. In order to avoid having to clean the channels of the distribution device when the colour or material is changed, it is provided that the distribution device is formed by a sleeve (8) which is arranged such that it can rotate between limit positions with respect to an external housing having supply channels (2, 3) for the plasticised materials, and has a number of channels corresponding to the number of materials to be sprayed, those supply channels (2, 3) which are intended to be connected alternately to the outlet cross- sections (15, 20) for the plasticised materials, terminating on the outside of the sleeve (8), offset with respect to one another by the same angular amount. …IMAGE…
