Abstract

A method for producing SZ groove type optic fiber comprises a receiving device having a cylindrical surface with alternatively reversed threaded grooves to receive the ZS groove line, characterized such that more than two places will be installed with a twist held means which will keep the SZ groove line processing along the center of the groove axis without any twist taking place, between two twist holding means, at least one guide means is provided to maintain the SZ groove line going in straight line without spirally rotating along the projected portion of the groove, while the optic fiber passing the guide means in the SZ groove , it will be wrapped with filaments and tape surrounding its outside.
