PURPOSE:To manufacture a tape type optical fiber cable with accurate shape by supplying a resin by a cross head to form the tape type optical fiber cable while moving an optical fiber core in the vertical direction. CONSTITUTION:Optical fiber cores 2 drawn out from supply bobbins 1 are turned facedown by a turn sheave 3 and are arrayed in a row at 1mm pitch. Optical fiber cores 2 are naturally centralized to centers in the lengthwise direction of rolls 4 while being guided by rolls 4 and are positioned on plane parts 4a and are arrayed in a row without gaps. A resin 5 hardened by ultraviolet rays is supplied to optical fiber cores 2 arrayed in a row without gaps by a cross head 7, and both of them are unified to form a tape type optical fiber cable 6. The resin 5 hardened by ultraviolet rays is hardened by an ultraviolet ray irradiator 8. Thus, the resin 5 hardened by ultraviolet rays is prevented from being irregularly deformed by gravity in the unhardened state to manufacture the tape type optical fiber with accurate shape. |
