front of the wire guide roller blocks regarded in the running direction of the wire the shifting rollers are concentrically mounted and axially displaceable and bear parallel guide grooves on the periphery thereof perpendicular to the axial direction and are spaced apart by an equal distance determined by the requirements of the wire enameling facility in the starting position the fastening portion 8 is again located immediately after the wire guide roller block 4 regarded in the running direction of the wire wire shifting rollers 9 and 11 are shifted fully outward axially at the beginning of the wire pull in so that the first guide grooves come to lie precisely under the wire fixed on the fastening portion 8 when the band 1 is set moving driven by wire guide roller block 2 and band roller 7 coupled therewith the fastening portion 8 trails the beginning of the wire fixed thereto placing it about wire guide roller blocks 2 3 and 4 and in the first guide grooves of wire shifting rollers 9 and 11 after each rotation of the band 1 the wire shifting rollers 9 and 11 are shifted inward by the distance corresponding to that between two guide grooves on wire shifting rollers 9 and 11 thus the wire is shifted axially by one groove interval on the wire guide roller blocks upon each rotation of the band making the next free guide grooves of wire shifting rollers 9 and 11 available for a further wire.
