International ClassD03D 049/04Foreign Application Priority Data1988-07-13 JPAbstractIn a looming system or method, warp yarns are mounted on a loom by the following four steps. At a first step, warp yarns of a full warp beam are drawn through a warp holding unit including a warp dropper unit, a heald unit and a reed. Then, at a second step, the full warp beam is mounted on the loom. At a third step, a warp tension is sensed between the warp beam and the warp holding unit. At a fourth step, the warp holding unit is moved toward the loom and mounted in the loom while rotating the warp beam so as to reduce a deviation of the sensed warp tension from a predetermined standard. | |
