To provide the subject regulator intended to prevent warp tension from partially loosening in the direction of weave width on a warp travel pathway from a feed beam to a tension roll.

This regulator 1 designed to feed sheet-like warps 2 from a feed beam 3 via a tension roll 5 to a cloth fell 9 has such a scheme that at least one tension regulation means 15 partially elastically movable in the direction of weave width is disposed over the whole range of the direction of weave width on a warp travel pathway from the feed beam 3 to the tension roll 5 and subjected to pressure contact on the warps 2 over the whole range of the direction of weave width.
