The invention relates to the technical field of weaving devices, in particular to a rapier loom preventing warp from being twisted. The rapier loom comprises two wrap beams, a warp feeding mechanism, a workbench, a weft feeding mechanism and a batching mechanism. The two warp beams are arranged in parallel. One leasing mechanism preventing warp from being twisted is arranged between one warp beam and the warp feeding mechanism, and the other leasing mechanism preventing warp from being twisted is arranged between the other warp beam and the warp feeding mechanism. The batching mechanism comprises a batching support, a plurality of batching shafts, a slip frequency chain wheel and a speed reducing motor. The batching shafts are installed on the batching support, the slip frequency chain wheel is installed at one ends of the batching shafts, and the speed reducing motor is installed below the slip frequency chain wheel and drives the slip frequency chain wheel to rotate. The rapier loop has the advantages that warp is prevented from being twisted, the weaving quality is good, and efficiency is high.
