ABSTRACT OF THE DISCLOSURE: A device for adjustably tensioning the weft in loom weaving from a stationary weft supply, to be applied at the side of the loom from which the weft is fed to the members carrying the weft through the shed. The device of the invention comprises a single support, a pair of elastic metal laminae, arranged substantially parallel to each other and on opposed sides of the path of the weft, one of the laminae being fixed with both ends to the support, the other metal lamina mounted cantilevered on the support, means acting on the other lamina to urge its free end into contact with the first lamina with an adjustable pressure for engaging the weft between the laminae and providing for the braking thereof, an oscillating lever having at one end a threadguide, through which passes the weft after engagement between the laminae and before reaching the carrying members and at the other end a small arm, means pivotally mounting the lever at the other end and adjustable spring means acting on the lever through the small arm to cause it to oscillate and move away from the laminae and from the members, in order to take up slack and retain tension in the weft.
