A loom (1) has feed motor (27) rotating a warp beam (3) in a direction to feeding warps (V) from the warp beam (3), a heddles (10) opening and closing the warps (V) fed off from the warp beam (3), a reed (13) beating wefts (H) inserted into the openings of the warps (V) by a weft inserting device (11), a surface motor (61) rotating a surface roller (17) to pull in the woven fabric (W), which has been beaten by the reed (13) and formed of the warps (V) and the wefts (H), in the pulling direction, a position detector (35) detecting the tension of the warps (V), and a control device 25 having an adaptive filter unit (83) filtering the tension detected by the position detector (35), and controlling the feed motor (27) and the surface motor (61) on the basis of the tension filtered by that adaptive filter unit (83) so that the tension of the warps (V) to a predetermined target tension.
