RING-SPINNING SYSTEM FOR PRODUCING YARN AND METHOD FOR ENDING THE THREAD SUPPLY TO THE DRAWING STAGE OF THE RING-SPINNING SYSTEM Russian patent published in 2022 - IPC D01H1/02 D01H13/04 D01H13/16 D02G3/32 

FIELD: spinning.

SUBSTANCE: invention relates to a ring-spinning system for producing yarn. Ring-spinning system (1) comprises a bobbin stand for retaining the bobbin (5) configured for a first thread (2) to be fed therefrom, a drawing stage (4) for drawing the first thread (2) together with a second thread (3) fed to the drawing stage (4), and a spindle. The ring-spinning system (1) also comprises at least one sensor (23, 24) for detecting a break in the first and/or second thread (2, 3) and/or the roving containing both the first and second threads (2, 3) and extending from the drawing stage (4), as well as a clamping unit (8) containing a clamp for securing the second thread (3) in the event that the sensor (23, 24) detects a break, wherein said clamp is provided near the bobbin stand. The clamping unit (8) herein is equipped with a knife element (19), wherein the knife element (19) and the clamp are adjacent to each other.

EFFECT: possibility of reconnecting broken threads if a break is detected in the first and/or second thread and/or the roving extending from the drawing stage.
