This invention has reference to means for tensioning yarns or the likeinlooms, w nd ing, doubling and other textile machines in which the rate of travelof the yarn or the like is subject toflvariation, and it has for its object to provide improved? means for taking up slack which may occur in the yarn or the like at certainplaces or times due to over-running of the supply or the f pull on the yarn or the like temporarily or momentarily decreasing or ceasmg.
A means for the purpose referred to, according to this invention, comprises a roller and a pressure member or members between which the yarn or the like passes and is lightly gripped, said roller beingpositively driven in the opposite direction to the travel of the yarn or the like so that it tends to travel the yarn or the like backwards and impart a slight retarding effect upon same. By these means the yarn or the like is kept always taut beyond the roller, and slack which may occur is at once taken up by the roller travelling the yarn or the like backwards.
In the accompanying drawings Figs. 1 and 2 are elevations at right angles to each other illustrating one embodiment of the invention, and Fig. 3 is an elevation illustrating a. modification thereof. Figs. t'and are elevations at right angles to each other of another embodiment of the invention, and Fig. 6is a. plan of Fig. 5.
Referring to the drawing, the embodiment of the invention illustrated in Figs. 1 and 2 comprises a air of rollers 7,8. The yarn 9 is drawn oil from a cheese 10 through a guide 11 and passes between the rollers 7 8 to a guide 12 whence it passes as required. The lower roller 7 is positively driven by a belt 13 engaging in a groove 14, or any other suitable means from an appropriate rotating part of the machine, in a direction opposite to that of the travel of the yarn. The upper roller 8 is of light construction and bears lightly upon the yarn. This latter is achieved by making the roller 7 of two diameters 7 7 b so as to provide between the part of lesser diameter and the upper roller 8 a space slightly less than the thickness of the yarn 9 which lies therein.
The rollers 7 and 8 are carried in a bracket 15, the upper roller 8 being mounted in slotted bearings 16 in which it-is free to 179.917, andin ,GreatBritainAprflB, 1920.
move vertically to adapt itselfto inequalities inthe thickness ojfftlie yarn 9. The surfaces of therollers may, if desired,.be covered with felt or any otl1er suitable material. p
Normally the yarn 9 is-drawl i freely. be tween the rollers 7,8 in the direction indicated by the arrows. W'hen, however, the travel of the yarn is interrupted, any slack which may occur therein atthe right side of the rollers 7 8 as shown in Fig. 1, is at once taken out and the yarn maintained taut at such side ofthe rollers, by the latter travelling the yarn backwards, i. e., to wards the cheese 1 In some cases the upper pressure roller 8 may co-act with two positively drivenlower rollers 7 as shown in Fig. 3, or, if desired, the yarn may pass between and be controlled bytwo or more sets of lower and upper rollers.
In the embodiment of the invention illustratedin Figs. 4, 5 and 6, the/lower roller 7 is provided with a. grooved periphery in which the yarn'lies, and theupper roller 8 aforesaid is replaced by oneor more balls 17 arranged in holders 18, from the lower ends of which they project to bear on the yarn lying in the groove of the roller. The holders 18 preferably consist of short tubes mounted in spring clips carried by the bracket 15 and have their lower ends gapped as at 19 to permit the free passage of the yarn 9.
In this embodiment of the invention, as before, any slack which may occur at'the delivery side of the roller 7 is taken up by the roller 7, acting in conjunction with the balls 17, travelling the yarn backwards. Balls 17 of different weight may be mounted in the holders 18 according to the tension it is desiredto maintain. on the yarn and two or more sets of rollers and balls may be employed.
The invention is especially applicable for use in shuttleless looms in which weft drawn from a supply at one side or both sides of the loom is inserted into the warp shed by needle-like or other inserting devices. In such application of the invention it serves to take up the slack which occurs in the weft during the return of the reed and slay after V beating up the picking position and so maintains the weft taut to ensure its subsequent \Vhat I claim as my invention and desire to secure by Letters Patent is 1. The improved means for tensioning yarns in looms, winding, doubling and other textile machines, comprising a roller and a pressure member or members between which the yarn passes and is lightly gripped, said roller being positively driven in a direction opposite to the travel of the yarn so that it tends to travel the yarn backwards, and so roller travels the yarn when slack occurs therein, substantially as set forth.
2. Tensioning means for yarn, according to claim 1, comprising the combination With the positively driven roller, of a pressure co-acting, therewith and between which and the driven roller the yarn passes and is lightly gripped, substantially as set forth.
3. Tensioning means for yarn comprising in combination, a positively driven roller and a pressure roller coacting therewith, one of said rollers having a portion of reduced diameter to provide between the rollers a space slightly less than the thickness of the yarn in which to receive the yarn. Y
In witness whereof I have hereunto set my hand.
