Abstract: A device for assembling ends of optical fibers into a sheet. Each of the ends is stripped of any resilient coating and has a flat terminal face. A grooved substrate is supported on a cradle means. An adhesive dispensing means deposites adhesive into the grooves. A gripping means grips the optical fibers to form the ends into a sheet and positions each of the optical fibers into the grooves of the substrate. A portion of each of the optical fibers, including the ends, extends beyond an edge of the substrate. A means holds a plate, having a flat surface, against the substrate where the plate covers the grooves to hold the optical fibers in the grooves and where the plate bonds to the substrate. The flat surface extends beyond the edge of the substrate to cover the portion of each of the optical fibers extending beyond the edge of the substrate.

Abstract: An adhesive product ?9! in the liquid state is deposited in a plurality of parallel, rectilinear, and equidistant grooves ?6i! formed in a flat surface of a substrate ?5!; each of the stripped ends ?1i! of the fibers in the sheet is introduced into a corresponding groove ?6i!, and the ends of the fibers are held in the grooves with the aid of a plate ?13! affixed to these grooves. In accordance with the invention, because the adhesive product ?9! is still in the liquid state, the entire collection of the ends ?1i! of the fibers extending from the grooves ?6i! is pressed against a facing flat portion ?13'! of the plate ?13! extending from the substrate ?5!, and this pressure is maintained until the adhesive product ?9! hardens and the plate ?13! is glued.
