The reed (20) for a high speed loom has a number of adjacent blades (21) in a row, held by an upper profile (8) and the lower reed profile (22) secured to the sley beam (12). The blades (21) have a section extending from the lower profile (22) in a width of about 6 mm and the width of the upper blade section is about 4 mm. <??>The blades (21) have a U-shaped recess, to form a weft guide channel (5) in the center section. The bottom section of the blades (21) have a rectangular shape within the lower profile (22), with a width of about 6 mm, and the upper blade sections have a rectangular shape with a width of about 4 mm within the upper profile (8). The leading edges (32,13) of the lower (14) and upper (16) sections of the blade (21) form a beat-up edge (31) at the recess. The blade (21) has a straight edge between the upper (8) and lower (22) profiles, at the side away from the weft guide channel (5). The bottom of the blade can be in a wedge shape, to match the wedge shape of the lower profile. The tapering wedge has a reducing width from the open side of the profile over a length which is one-third to one-half of the profile depth, leading into a rectangular shape with a reduced width. The length of the rectangular section is about equal to the length of the tapering wedge shape. |
