Reed for air weaving looms comprising a plurality of side-by-side dents, each dent being provided with a wide central recess (C), which separates an upper portion from a lower portion of the dent, for forming the reed launching channel, said central recess (C) being limited at least by a lower wall (L2), a bottom wall (L3), an upper wall (L4), two inner curved arcuate connecting surfaces (R2, R3) which connect said walls to each other and an outer arcuate connecting surface (R1) which connects said lower wall (L2) to the outer wall (L1) of said lower portion of the dent. One end of the outer arcuate connecting surface (R1) is tangential to said lower wall (L2) and its other end forms an angle other than 0° with said lower outer wall (L1) of the dent.
