METHOD FOR MANUFACTURE CYLINDRICAL PRINT WINDING Russian patent published in 1996 - IPC

FIELD: electrical engineering. SUBSTANCE: cylindrical print winding is formed from blank by bending it through 180 deg at least once. Blank has flexible base carrying desired quantity of printed conductors. Conductors are formed so that main sections are alternating with reduced-width ones. In the course of bending of blank trapezoidal board is obtained, rolled into cylinder across line of bending, and printed conductor ends are electrically connected. EFFECT: provision for dispensing with additional insulating layers when making winding involving multiple bending of blank; elimination of conductivity error associated with accuracy of alignment of lines of bending with conductor patter increasing with quantity of winding layers; provision for alignment of ends of strictly determined printed conductors when manufacturing cylindrical print winding due to reduced-length sections of printed conductors. 4 cl, 11 dwg
