A full-automatic positive let-off motion for looms developed by the author is described in this article. The author defines the length of warp let-off by this new device as the displacement of the feeling roller, i.e., as the change of the angle of inclination of the weight lever. It is necessary, then, to know the effects of the change of the angle of inclination of the weight lever on the length and tension of the warp let-off. For this purpose the author has derived theoretical formulas.
On the basis of these formulas, it is certain that the maximum amount of the swing of the weight lever falls within the limits permitted for woven fabrics.
