Abstract
A method for manufacturing a thread, includes introducing fibers into a rotor having a fiber collecting groove, combining the fibers in the collecting groove into a fiber ring gradually converting into a thread, conducting the thread in a given travel direction through a pneumatic twisting device discharging a quantity of air, bringing the thread in contact with an air stream in the pneumatic twisting device which rotates around the longitudinal axis of the thread against the given travel direction of the thread, conducting fibers loosened from the thread back into the rotor with at least part of the quantity of air discharging from the pneumatic twisting device, drawing off the twisted thread leaving the pneumatic twisting device, and conducting the twisted thread to a thread collecting device, and a device for carrying out the method.
