PROBLEM TO BE SOLVED: To carry out excellent weaving by a simple constitution in an let-off device which has a plurality of easing rolls and with which warps are divided into a plurality of parts and sent for each easing roll. SOLUTION: In the let-off device 1 for a loom with which warp sheets 5 from one delivery beam 4 are divided into a plurality of parts, independently guided to each of the easing rolls 2 and 3 and a warp opening 9 is formed for each of the warp sheets 5a and 5b, the delivery beam 4 is driven on the basis of tension of only the one warp sheet 5a so that warp tension has set tension for one warp sheet 5a and the easing roll 3 corresponding to the other warp sheet 5b makes only an easing movement by an easing apparatus 14 for other warp sheet 5b.
