ABSTRACT:
A reed A for a loom is disclosed which includes a front row B of dents 30 on the beat-up side of the frame and a back row C of dents 34 staggered in alignment with dents 30. An upper support bar D and lower support bar E support the dents 30, 34 in the reed. Upper support bar D includes mounting bars 42, 44 which are reduced in height compared to a main bar element 40 such that dents 34 have a greater free height in the reed than dents 30 rendering them more flexible. Upper support bar D which is on the free unclamped side of the reed during beat-up is thus rendered lighter than lower support bar E which is on the clamping side to reduce inertial loading on the frame. The front reed dents will offer a strong reed to the beat-up. Since the back reed is required only to separate the adjacent warp ends it is made as flexible as possible by increasing the height. In this way, the back reed offers less resistance to the yarn passage reducing the lint buildup between the dents and increase efficiency by offering a larger opening to the warp yarns.
