Air jet spinning machine and drafting system unit for a spinning unit of an air jet spinning machine

A drafting system unit for a spinning unit of an air jet spinning machine for producing a thread or roving from a supplied fiber strip, with

• at least one front roller pair consisting of a front top roller on a load carrier and a driven front bottom roller on a bottom roller carrier and forming a clamping line, and
• a bearing element arranged on the bottom roller carrier for movably bearing an air jet spinning nozzle having a nozzle carrier,
• characterized in that
• the bottom roller carrier comprises a guide element and the bearing element, wherein the guide element has a guide surface, wherein the bearing element has at least one free end, via which the air jet spinning nozzle can be received, wherein the bearing element forms a pivot axis for pivoting the air jet spinning nozzle between an operating position and at least one second position spaced apart therefrom, wherein the bearing element is connected to a portion spaced apart from the at least one free end on the bottom roller carrier, wherein the guide element is arranged on the bottom roller carrier and having the guide surface extending parallel beyond the at least one free end and at a distance from the bearing element, and wherein the air jet spinning nozzle is brought into contact with the guide surface by the nozzle carrier and, as the nozzle carrier is disposed against the guide surface, the air jet spinning nozzle is pushed via the at least one free end of the bearing element until the nozzle carrier rests against a portion of the bearing element.
