Japanese Patent JP5499228
Kind Code:
B1
Abstract:
To wrap an optical fiber bundle in a press-wrapping tape while guiding the optical fiber bundle. A former of the present invention includes: (A) a guide pipe that guides an optical fiber bundle configured from a plurality of optical fibers; (B) a tape forming section that forms a press-wrapping tape from a strip shape into a helical shape, while guiding the press-wrapping tape along a feed direction, the tape forming section including a curved section that gradually curves the strip shaped press-wrapping tape while guiding the press-wrapping tape along the feed direction, and a helical section that is a helical tube shaped location further to a downstream side than a position where two edges of the curved section intersect with each other, the helical section causing two end portions of the press-wrapping tape that has been curved with the curved section to overlap and forming the press-wrapping tape into a helical shape, while guiding the press-wrapping tape along the feed direction, and gradually narrowing an external diameter of the helical shaped press-wrapping tape, wherein (C) an outlet of the guide pipe is disposed further to the downstream side than the position where the two edges of the curved section intersect with each other.
