Abstract (en)

This method is for cutting pile warp yarns (I, II, III, IV, V) in a double carpet weaving loom (2) where pile warp yarns selectively extend between an upper ground fabric (G1) and a lower ground fabric. These warp yarns are cut by a cutting device (6) including a knife carriage (64) which, in order to perform cutting operations, has translation movements (F, B) from a first side (G1 L) of a ground fabric (G1) to a second side (G1 R) of the ground fabric (G1). Each translation movement (F, B) of the knife carriage (64) takes place within a pick (P1-P9). Moreover, each translation movement (F, B) of the knife carriage (64) is controlled on a pick by pick (P1-P9) basis.
