Spinning machine and method

Abstract

To provide a fiber machine achieving more flexible negative pressure distribution in a spinning apparatus to serve in negative pressure for thread production together with a suction nozzle to serve in negative pressure to find a thread end part on a bobbin.SOLUTION: A fiber machine can include at least one 2nd negative pressure system. This 2nd negative pressure system can be designed and arranged so as to be withdrawn to a fluid connection part with a 2nd negative pressure point. Alternatively, a 2nd negative pressure system can be designed and arranged so as to become a fluid connection part with a 2nd negative pressure point. To make a structure of the fiber machine be more flexible, to further improve distribution of negative pressure, and to make distribution of negative pressure to be more flexible, a connection part between a 1st negative pressure system and a 2nd negative pressure system is designed to establish or shutdown the connection part selectively.SELECTED DRAWING: Figure 1
