The present invention relates to an apparatus for manufacturing reinforcement meshes and spinning stations therefor. Reinforcement rods to be joined with the spinning wires are supplied by advancing means from the rear end of the apparatus, and a special mechanism prevents that the wire breaks during its encounter with the reinforcement rod.

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.

A method for starting a spindle of a cabling or two-for-one twisting machine, wherein a yarn reserve is formed on a take-up package, the machine has a workstation having a spindle pot for holding a first feed package and having a spindle rotor with a lateral outlet below the spindle pot, an outer yarn from one feed package is wound around an inner yarn from another feed package and the outer yarn is guided through the spindle shaft and its lateral outlet in a balloon orbiting the spindle pot to a yarn-guiding device above the spindle which merges the two yarn supplies, and a winding device in which the produced twist is wound onto the take-up package. A ratio of the take-up speed of the twist to the rotation speed of the spindle rotor is increased in comparison with the production data is used during creation of the yarn reserve.
