METHOD FOR MANUFACTURING AN OPTICAL FIBER SPOOL WITH SELF-SUPPORTING COIL OF AN OPTICEL FIBER AND OPTICAL FIBER SOOL

摘要

#CMT# #/CMT# The winding of superposed layers of a fiber optic line is formed as a crossed-winding. Several projection portions (86) are provided at surfaces (76) of fiber optic line. The projection portions are arranged at the gaps (88) that are formed between the fiber optic lines. The projection portions arranged at the contact surfaces (92a,92b) of specific adjacent layers (96a-96c) of fiber optic lines are engaged with other adjacent layers of the same contact surfaces. A solid portion of the fiber optic line is made of plastic base. #CMT# : #/CMT# An independent claim is included for glass fiber coil. #CMT#USE : #/CMT# Manufacturing method of glass fiber coil (claimed) of optical fiber cable. #CMT#ADVANTAGE : #/CMT# The glass fiber coil is manufactured effectively such that a safe and easy unwinding of the glass fiber coils is ensured by the layers of the fiber optic line to be fixed in a specific position. The surface of the fiber optic line is roughened by the partially distributed projection portions or the friction coefficient of the surface of fiber optic lines is increased. The exact shape of the glass fiber coil is maintained even without the usage of adhesive material. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the glass fiber coil. 76 : Surface of fiber optic line 86 : Projection portion 88 : Gap formed between fiber optic lines 92a,92b : Contact surfaces 96a-96c : Adjacent layers of fiber optic lines.
