Abstract

Provided are cord reinforcer manufacturing method and apparatus, which can improve the manufacturing efficiency of a cord reinforcer to be arranged in an annular reinforcing object and which can improve the manufacturing precision of the cord reinforcer. A cord (C) is fed to the circumferential portion (18A) of an index rotor (18). This index rotor (18) is rotated on the axis, and a disc (12) is so rotated on the axis that its portion confronts the circumferential portion (18A) of the index rotor (18). When the cord (C) is moved to the position to confront the disc (12), the cord (C) is pushed from the circumferential portion (18A) of the index rotor (18) and adhered to the disc (12) by a cord holder (62) and a hammer (64), which can make frequent appearances to and from the circumferential portion (18A).
