2123504 9310543 PCTABS00022 The individual coils (7) with the canted section wires (10) are arranged on the wire stranding head (1). So-called twisting or transposing of the individual section wires (10) is carried out in the twisting head (3). The twisted conductor (11) thus produced in the twisting head (3) is wrapped with various plies of insulating paper in the subsequent insulation braider (4). A caterpillar pull-off (5) capable of swivelling in order to adapt to the bunched dimension of the twisted conductor pulls the twisted conductor (11) from the twisted conductor machine. A winding device (6) mounted downstream of the caterpillar pull-off (5) has a transverse expansion mandrel (12) movable inside a frame (13) in the vertical as well as in the horizontal directions. In addition, this expansion mandrel (12) can also swivel in the horizontal plane. A carrying cylinder (14) that afterwards can be directly laid on the transformer core is arranged on this expansion mandrel (12). This device allows for the first time the winding material producer to produce a complete transformer winding. According to the calculations and design data, the winding can be finished directly after production of the conductor.
