Abstract

A process is disclosed for consolidating and coating an air-core coil (3) with a winding made of naked electroconductive cables (5) made of twisted wires of substantially rectangular cross-section wound one or several times. A liquid duroplastic synthetic resin mixture is poured on the upper end of the pre-dried coil of the air-core coil rotated around its vertical axis in an impregnating station and flows downwards along the inner and outer surfaces of the coil, if required also between the layers of the coil winding, partially entering the intermediate spaces between the wires of which the conductive cable (5) is composed. The excess of synthetic resin mixture is collected and re-used, and the air-core coil (3) is then cured at a higher temperature. A device for carrying out the process has a chain conveyor system which moves hanging treatment units constituted of a revolving ring (10) to which is secured the air-core coil (3) between several working or processing stations. In the impregnating station (2) the revolving ring (10) is coupled to a driving device (21) in order to rotate the air-core coil (3).
