Claim:
Process for selectively lacing filaments on multi-dimensional textile preforms provided by rods ( 2 ), in which the rods are replaced by the filament, the rods being pushed vertically downwardly by a needle ( 3 ) of the type having an open eye which, after passing through the piece to be laced ( 1 ) and ejection of the rod ( 2 ) is opened at a so-called filament insertion station ( 9 ) to receive the filament ( 21 ) to be laced, then is raised to pass the filament into the space freed by said rod, characterized by the following steps: there are first prepared a plurality of different filaments ( 21 ) disposed in a ready position in parallel, the desired filament ( 21 ) is selectively brought facing said filament insertion station ( 9 ), the necessary length of the selected filament is pre-delivered, the filament ( 21 ) is presented and moved into the eye ( 4 ) of the needle ( 3 ) such that the hook of the needle is located substantially in the middle of the length of the filament to be laced, the needle ( 3 ) is raised and the double filament ( 21 ) and, if desired, at the end of rising of the needle the filament is cut in line with said insertion station ( 9 ).
