摘要： The warp threads (Ka) are clamped as a thread layer, are divided off individually from this and are stretched with a simultaneous measurement of the tensile force and/or stretching. These operations take place before the weaving process in a step of the weaving preparation process in which the warp threads are in the form of a prepared warp-thread layer. The device contains means (1, 2) for clamping the warp-thread layer, means (4) for dividing off the warp threads and means (FP) for measuring the tensile force and/or stretching of the divided-off warp threads, the means (1, 2) for clamping the warp-thread layer forming an integral part of a warp preparation machine, preferably of a knotting unit or of a drawing-in unit.

摘要： A method for producing multiple fiber data from a plurality of single fiber tests. A plurality of individual fibers are subjected to tension tests such that the individual fibers are elongated tensioned and broken while characteristics of the fiber are monitored. Multiple fiber data are obtained by testing a number of fibers from a sample and superimposing the graphical representation of tensile characteristics of the individual fibers upon one another to obtain a composite representation which constitutes multiple fiber data. Characteristics of individual fibers which may be combined to obtain a composite representation constituting multiple fiber data include such characteristics as tension, elongation and cross-sectional characteristics of the fiber.

摘要： A device for supporting a long cable to permit the ends of the cable, such as swaged end fittings, to be tested by a conventional tension/compression tester. The device includes a drum upon which the cable is wound. The drum is supported by a pair of vertical flanges which in turn are connected to a movable platform of the tension/compression tester. One end of the cable is connected to a fixed base of the tester. A small section of the remaining portion of the cable that is not wound around the drum is engaged by a movable clamp which is fastened to one of the vertical flanges. The cable is tested by movement of the platform away from the base until a predetermined load is reached. A majority of the applied force is absorbed by the portion of the cable that is wound on the drum. The remainder of the applied force is absorbed by the adjustable clamp. Consequently, during the test there is limited slippage of the cable on the drum.

摘要： An arrangement for measuring the static lives of glass optical fibers. The arrangement comprises a number of holders. In each holder a rod with a fiber wound on it can be arranged. The holder surrounds each rod on three sides. Upon rupture of a fiber the broken ends strike the enclosure and eject the rod from its holder. Means are provided for recording the instants of insertion and ejection of each rod in and from a holder.

摘要： A method of proof testing an optical glass fibre by pulling it around a free roller whose radius is sufficiently small to impart the strain necessary to detect fibres whose surface or near surface flaws weaken the fibre below a required strength. Proof testers are disclosed incorporating, single rollers, a set of three parallel rollers and a jig holding four sets of three rollers. Proof testers incorporating the extra rollers whose axes are at different angles are shown to more thoroughly explore the surface of the fibre for cracks.

摘要： A method of adjusting a given pretension in threads on tensile strength testing apparatus. A force measuring device is used as an adjusting member for the pretension, from where the tensile load increases and the elongation thereby appearing is measured. The loose thread inserted into the thread clamp is either pretensioned by means of a movable testing clamp, or the thread is stretched by a transport device until the force measuring device indicates the given pretension value.

摘要： Fibers, particularly optical fibers, are tested for determining their tene strength in expected environments. A pair of sheaves, on journaled and the other fixed receive a looped length of fiber and are placed within a cylindrical shell which is filled with an expected environmental medium, such as seawater. The sheaves are pulled apart subjecting the fiber to tensile loading and a strain gauge provides responsive read-outs so that the fiber's fatigue strength can be determined. The size of the sheaves and adhesively securing the loose ends of the fiber prevents the generation of any spurious pinching torsional stresses. Placing the fiber in the environmental fluid allows a monitoring of the effects of the fluid on the fiber's cladding and core so that the strength limits of the fiber are accurately determined under simulated operational conditions.
