The present disclosure discloses alloy filament and simple yarn blending equipment and a process, and belongs to the technical field of textiles. The equipment comprises a machine head, a machine body, a machine tail, and a computer control box arranged on one side of the machine head; and an upper roller, a first covering spindle, a second covering spindle, a heat setting box, a lower roller, and a winding device are sequentially arranged in the machine body from top to bottom. The equipment is technically modified through the solution to achieve completion of the procedures such as covering, twisting, spooling and the like of the yarn on one piece of equipment, the yarn is integrally formed, the process is the first in China, and is equivalent to a chip in the spinning industry, the labor as well as time and energy are saved, and economic efficiency is greatly improved.

An air-jet type spinning device (4), comprising a body (8) at least partially hollow which defines a spinning chamber (12), a fibre feed device (16), facing said spinning chamber (12) so as to feed the fibres into the spinning chamber (12), a spinning spindle (20) at least partially inserted in the spinning chamber (12) and fitted with a spinning channel (24) for the suction of yarn obtained from said fibres, the spinning channel (24) defining a spinning direction (X-X), at least one channel (28) for sending a jet of compressed air inside the spinning chamber (12). Advantageously, the spinning chamber (12) is delimited at least partially by an outer side wall (32), opposite the spinning spindle (20), wherein at least one thread (36) is made on said outer side wall (32), wherein said at least one channel (28) is oriented so as to direct the jet of compressed air towards the at least one thread (36) in order to be guided and oriented by the latter.

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.
