<p>PURPOSE:To obtain a reed saving consuming amount of pressurized air and having excellent stability of weft-inserting at high speed by setting air- converging angles satisfying specific conditions at both the parts of upper and lower jaws forming dents of a reed-introducing groove, setting an air-diffusing angle at an interior part and providing an edge part having a specific radius of curvature at the interior part. CONSTITUTION:Air-converging angles thetaA and thetaB satisfying relations of 0 deg.<=thetaA, 5 deg.<=thetaB<=30 deg. and thetaA<thetaB are set at an upper jaw part A and a lower jaw part B forming an introducing groove G in dents of a reed 1. Further, an air-diffusing angle thetaC is set at an interior part C in said introducing groove G and simultaneously a radius of curvature of edge part on a main nozzle side in said interior taper part is made to <=0.02mm to increase air-converging effect and inhibit flying out of weft from the reed groove G.</p> |
