Sätt och anordning för att bilda en bandkabelliknande struktur av lösa optiska fibrer, samt adhesivt band

摘要

Optical fibers (1) which are disposed in parallel and at each other in a plane, are fixed in this position by pieces of tapes (3) provided with an adhesive (7) on their surfaces facing the fibers so that the tape pieces are located exactly opposite each other on the two large surfaces of the parallel fiber assembly. The tape pieces can extend exactly up to the lateral edges of the assembly but can advantageously be a little longer, so that adhesives from the opposite tape pieces come in contact with each other at the lateral edges of the assembly. The tape pieces are advantageously cut off from specially designed retainer tapes having openings which are provided in pairs with the openings of each pair placed opposite each other at each of the edges of the tapes. The assembly is placed so that it extends over the two openings of a pair of openings, crossing or perpendicular to the longitudinal direction of the tapes. Then a cutting-off or more particularly two cuts are made in the tape, using knifes (17), only between the openings of the pair, from one opening to the other one. Then a piece of the tape between the openings is separated which adheres to the assembly and keeps it together. Between the knifes (17) a cushion (13) of an elastic material is provided which in a cutting-off movement presses the tapes in a direction towards a counterplate (15).
