Document Type and Number:
Japanese Patent JP2521134
Kind Code:
B2
Abstract:
PURPOSE:To surely hold tape type optical fibers into spiral grooves by providing a rotary twisting die which is positioned on the downstream side of a rotary eyeboard in the feed direction of an S and Z compose slot and is provided projectingly with the projecting parts holding the tape type optical fibers on the inside periphery. CONSTITUTION:The tape type optical fibers 5 guided by a stationary eyeboard 15 are further guided by the rotary eyeboard 18 and are inserted into the prescribed spiral grooves 2 by the rotary twisting die 23. The projections of the rotary eyeboard 18, i.e., screws 29 of a fitting body 21 and the projecting parts of the rotary twisting die 23, i.e., screws 29 of a fitting body 26 are fitted into the spiral grooves 2 and, therefore, the rotary eyeboard 18 and the rotary twisting die 23 turn as the S and Z compose slot 1 progresses. The rotating direction thereby inverts at every one rotation. The projections of the rotary eyeboard 18 and the projecting parts of the rotary twisting die 23 are constituted of the screws 29 and, therefore, the amt. of the projections to be fitted into the spiral grooves 2 is optionally adjustable.
