Optical fibre laying head for cable production

摘要

A head for laying optical fibres in a helically grooved cable core consists of a freely rotating mount assembly carrying fibre guides inclined on the axis of travel of the core with an angle smaller than 45 DEG . The fibre guides are elastic hollow tubes ended by a bevel maintained on the bottom of the associated groove. An optical control unit is provided for correct positioning of the mount when starting to lay.
