Abstract: A clamping holder for flexible lines, particularly current-carrying lines, has a line holder with at least one device for fixing a line and a device clamping the line in the device. The device and the line holder have at least one mutually aligned passage, respectively. A known type of elastic, longitudinally extendible tension device is pulled into the passages. The tension device has a neck-type cross-sectional contraction and connects the line holder with the device in a ventable manner.

Abstract: The invention relates to an auxiliary blow nozzle for air jet weaving machines which permits a symmetric division of the warp, said division protecting the structure of the warp threads, when the blow nozzle is immersed in the warp. To this end, an envelope curve (5) which describes the free end (1b) of the nozzle body (1) and which has a radius (R.sub.1) runs at an angle (.alpha.) relative to the longitudinal axis (4a) of the approximately elliptic cross-section of a nozzle body end area (1a). The surfaces (6, 7) originating from the envelope curve (5) slope downward on both sides to the outer periphery (4) in a manner similar to a roof, and said surfaces (6, 7) thus enclose an angle (.beta.). The respective surface (6, 7) having a radius (R.sub.2) graduates into the outer periphery (4). A radius (R.sub.3) connects radius (R.sub.1) of the envelope curve (5) to the outer periphery (4), and each surface (6, 7) constructs an arc-shaped surface section (6a, 7a) which slopes downward at an angle (.gamma.

Abstract: A tentering chain is assembled of inner links and outer links or link plates interconnected by journal pins passing through the outer link plates and through the inner links so that the latter are positioned between the outer link plates. The inner links have plates which are provided with integral bearing bushings that are interconnected at a junction (J) formed by pressing four bearing bushings together with a transition fit after a bearing roller has been placed on each of two of the four bushings to form the inner links. The inner link plates form with their bearing bushings two chain link sections (1, 2) that are easily interconnected at the junction (J) and also easily disconnected again at the junction. Both sections are made by casting or drop forging.

Abstract: A holding and guiding mechanism (5, 5') for connecting shaft drive rods (6, 6') in a loom includes a plurality of parallel guide tracks arranged next to each other and extending substantially vertically and defining a guide curve for a prescribed motion path of the drive rods (6, 6'). The guide curve is preferably formed by a circular guide track for a respective drive rod. The upper end of each drive rod is connected through cooperating first and second couplings to one of the heald frames and the lower end of each drive rod is journalled to a shaft drive (8D) for the shed formation when the respective drive rod is an active rod connected to the heald frame or when the respective rod assumes a passive state in which it is also held in the drive and holding mechanism, but the coupling at the upper rod end is disconnected or decoupled at this time from the heald frame.

Abstract: A guide mechanism for a weft thread inserting gripper rod in shuttleless looms, has upwardly open U-rail mounted in a gripper rod housing for guiding at least a portion of the reciprocating gripper rod in the housing. Additionally, guide rollers position adjustably mounted in a bracket are located in an operating position for guiding the gripper rod outside the gripper rod housing. The bracket is either tiltably or removably mounted to the loom frame for bringing the guide rollers into an inoperative position in which the gripper rod is easily accessible for disengagement from its drive sprocket and removal out of the gripper rod housing. The guiding by the U-rail and by the guide rollers effectively prevents gripper rod vibrations, yet permits an easy access to the gripper rod.
