Abstract

Automatic thread tensioner applicable to textile machines, of special use in warping machines, characterized essentially by the fact of being constituted by a support body of variable shape and size, provided with two end walls in which both nozzles are mounted for inlet and exit of the thread to be tensioned, as well as of other walls or interior partitions properly distributed, in which there are as many nozzles for driving said thread, the mentioned support being also provided with the suitable means for its attachment to the corresponding machine, and figuring within it, duly articulated by its middle part, a rocker arm provided with walls with nozzles that come to be interposed between the fixed ones, whose rocker is equipped, on the one hand, with a variable position spring arranged attached to a point of said rocker out of the articulation of this and a sliding button along a recess made in a wall of the general support, whose button can be immobilized to vary the tensile force of said spring, and, on the other hand, with a pneumatic system determined by a cylinder integral with the rocker itself and by a piston linked through a tie, with the fixed part of the assembly, the tensioning of the thread taking place by the more or less marked inclination of the rocker in its support, inclination that determines a zigzag line more or less broken of said thread that passes through the Fixed and movable nozzles all according to their initial looseness state, varying the position of the rocker, which is always requested by its adjustable spring, in line with the tension of the wire at its entry into the device.
