Suction device for a textile machine, textile machine with a suction device, use of two cyclone elements, and method for suctioning yarns

A suction device for a textile machine, wherein the suction device comprises two cyclone elements for generating a vortex flow of compressed air arranged one behind the other in a suction direction, so that the yarn can be guided through a first cyclone element and then through a second cyclone element, wherein each cyclone element comprises a cyclone axis and the cyclone axes are aligned coaxially, a suction pipe for guiding the yarn and a suction element for generating a suction pressure, a mouthpiece for introducing at least one yarn, the mouthpiece comprising at least one opening on a circumference of the mouthpiece on an inner side of the mouthpiece, and an air delivery system constructed and arranged such that the air delivery system serves as an air supply to the mouthpiece and at least one of the cyclone elements, wherein air flow can be introduced into the mouthpiece through the at least one opening, wherein the at least one opening is aligned in the suction direction so that the air flow introduced through the at least one opening flows in the suction direction.
