摘要

Improvements in the provisions for tensioning fabrics in the looms, characterized in that the fixed part of the elements that are rotationally related to the marginal areas of the fabric subjected to tensioning in the transverse direction, immediately to its formation, is coupled to slides mounted on a stable support fixed on the frame of the loom, which slide consists of two guides parallel to each other and joined at their ends, in which one of these ends has a trunnion in transverse direction, suitable for said coupling, while the other end presents in longitudinal direction a threaded rod of adjustable position, being lodged between the two guides of the slide two bearings mounted on the said fixed support and against which the inner faces of the mentioned guides of the slide are applied, there being a helical spring that operates by tension and arranged between the support and the slide for effects to place the latter in its rest position in which the adjustable stem makes a stop with the immediate bearing, all this in such a way that the margin of elastic displacement of the slide allows compensating eventual retreats that the free-turn tensioning elements exert sporadically during operation along the fabric, in order to retain the width thereof.
