Document Type and Number:
WIPO Patent Application WO/2018/190065
Kind Code:
A1
Abstract:
A manufacturing method for an optical fiber cable comprises: an SZ twisting step for SZ twisting a plurality of optical fibers (3) or a plurality of optical fiber units (5) using an SZ twisting device (12) to form an optical fiber bundle (B); and a covering step for covering the optical fiber bundle with a sheath (101) using an extrusion molding device (14), wherein in the covering step, the optical fiber bundle is covered with the sheath while the optical fiber bundle is being pressed by a pressing part (13) disposed between the SZ twisting device and the extrusion molding device.
