Abstract (en)

[origin: JP2021066993A] To provide a convergence device enabling manufacturing of uniform yarns and a draft device for a convergence device.SOLUTION: The invention relates to a convergence device and a draft device for a convergence device. The convergence device is a convergence device for a draft device for a spinning machine, especially a ring spinning machine for convergence of a drafted sliver, the convergence device provided with a convergence zone which allows forming of a suction flow vertically to a fiber transportation direction by using a suction opening 4. In order to provide a convergence device enabling manufacturing of uniform yarns and a draft device for a convergence device, the convergence device is provided with a convergence element assembled with a guide roller, the guide roller can be arranged opposed to the suction opening 4 in a convergence zone area in a manner capable of turning in the fiber transportation direction so that a sliver engages with the guide roller.SELECTED DRAWING: Figure 1
