A method and apparatus for manufacturing carpets with an antique appearance using an automated weaving machine. The system integrates advanced control of warp tension, specialized pile yarn, and a unique reed and lancet assembly to replicate the randomized wear patterns, variable pile heights, and textural intricacies characteristic of aged carpets. A blend of synthetic and natural fibers undergoes a proprietary crimping, spinning, and two-stage dyeing process, producing multicolored yarn with pseudo-random shrinkage properties. Warp threads are precisely positioned using weighted beams and tiered lancets, enabling the creation of areas with zero and non-zero pile heights, separated by gradual transition zones. The resulting carpets exhibit high aesthetic authenticity and structural durability. A chi-squared statistical process ensures the randomness of worn patterns, optimizing the antique effect.
