The invention relates to a process for the production of a face-to-face carpet fabric on a double pile loom having at least two filling insertion planes, using filling yarns (SR, SI), stuffer warp yarns (FK), and chain warp yarns (B) to form the two back cloths (OW, UW), whereby the filling yarns (SR, SI) are inserted into each back cloth as back fillings (SR) and inner fillings (SI) and whereby groups of chain warp yarns (B) whose individual yarns between their respective last binding to an inner filling (SI) and the succeeding last binding to a back filling (SR) form a holding length (Y), are assigned to each back cloth. With the object of achieving an always vertical tie-in of the pile loops in the back cloth, a high pile density, and a saving of chain warp yarns, all patterning pile loops (PM) are stretched over back fillings (SR) and the pattern repeat (R) of a group of chain warp yarns (B) is selected to be greater than six. The holding lengths (Y) of a chain warp yam (B) extend over at least three filling insertion cycles. The number of chain warp yarns (B) per group distributed over at least two warp courses (K1, K2) is given by the number of back filling bindings of a chain warp yam (B) in the holding length (Y) and the length of the pattern repeat (R) selected. (FIG. 1, 1a).
