A pile fabric loom includes a frame, a pile warp beam, a terry motion roller and a pile warp tension adjuster. The pile warp beam is supported by the frame. The terry motion roller serves to guide pile warp yarns let off from the pile warp beam toward cloth fell. The pile warp tension adjuster is operable to adjust tension of the pile warp yarns. The pile warp tension adjuster has a leaf spring that is located along a path of the pile warp yarns extending from the pile warp beam to the terry motion roller. The leaf spring extends in longitudinal direction of the loom and a first end and a second end. The first end is fixed to the frame. The surface of the second end is in contact with the pile warp yarns. The leaf spring is elastically deformable by the tension of the pile warp yarns.
