摘要: A process is provided of yarn spinning and/or twisting, in which a yarn runs between a yarn feeder towards a yarn picker. A driver rotates the yarn picker at a predetermined speed, in which a stretch of balloon is generated in a point located between the yarn feeder and the yarn picker by the presence of a ring. A helical path with oscillating spiral diameters exists between the yarn feeder and the yarn picker, so that the path of the yarn through the ring, creates a body of revolution from a diameter generating a balloon that has at least a hyperboloid structure forming at least two stretches of balloons consecutive to each other. A machine for performing the process is also provided.

摘要: A method for transforming a yarn spinning and/or twisting machine and the yarn spinning and/or twisting machine modified according to the method to increase the height (h) of the balloon region zone (a), between the upper and lower ends thereof is provided. In order to provide the zone with two or more balloon regions (a), with means for feeding (1) the thread (2) using conventional upper guides (3), and means for tensing (4) and rolling (5) the thread (2) onto a lower collection reel (6), includes elimination of the conventional guide means (3); and the incorporation of an additional guide accessory (3′) immediately after the feed means (1), including for example, of a clip (30) or a set of rollers (32) optionally with a conveyor belt (33).

摘要: Process to set the optimal working height between the thread entry point and the thread exit point in a twisting and/or thread spinning machine, and a twisting and/or thread spinning machine that applies such process including: identifying the variation of tension of the thread produced by the variation of the winding diameter (d) of the thread (8) on the bobbin (5), depending on the position of the rocker (6), or the winding diameter of the thread on the bobbin (5); carrying out the displacements from the thread entry point (PE) and/or from the thread exit point (PS) to obtain a distance (LB) between both in which the variations of tension counter each other.

摘要: An ultralight flat-weave fabric including more than one wefts and their directions that intersect with one another to form a particular angle in relation to the warp, and a warp. The weft and warp are supplied with fibers or fabrics having a cross-section in the form of a flat tape. In this way, it is possible to product a woven fabric in which two weft tapes having different directions are combined with the warp tape, such that stresses in six different directions are absorbed in a single fabric layer without multiple fabrics having to be overlapped. The woven fabric is completely covered, has a weight-to-surface area ratio of 2, and, as a result, is very light.
