Abstract

A weaving loom for weaving a multilayer fabric with weft insertion mechanism (90) and main heddles moved by a Jacquard main shedding mechanism for guiding main warp yarns (12) and defining a main harness width (W11). According to the invention, the weaving loom includes auxiliary heddles (21) moved by an auxiliary shedding mechanism, for guiding auxiliary warp yarns (22) and defining a clamping area (W21) arranged within the main harness width (W11). At a first pick, the auxiliary heddles are configured for closing the auxiliary shed of auxiliary warp yarns for clamping an inserted weft (100) while the main shed is still open.
