Title: Untwisting nozzle of piecing device
Inventor: KIMURA HIDETOSHI
IPC: B65H69/06
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To increase the untwisting property of a thread in an untwisting nozzle by forming a part in contact with a thread end absorbed in a suction port of the untwisting nozzle in such a way that the stress which acts on the thread end is dispersed. SOLUTION: An untwisting nozzle 1 consists of a suction port 5 which absorbs untwisted thread ends, a nozzle 4 which jets air from an air supply source to generate a turning stream of air, and a nozzle space 7 which untwists thread ends. The suction port 5 and the nozzle space 7 are brought in contact mutually and continuously. An inside diameter of an opening end of the suction port 5, namely, a thread contact face 6 with which the absorbed thread comes in contact, is curved in such a manner that a thread end absorbed into the nozzle space 7 is not bent in its middle and is not bent at a sharp angle. Moreover, a surface of the thread contact face 6 is smooth so that a thread can turn freely.  For this reason, the twisting in the direction of untwisting does not stop on the thread contact face 6 and is continuously transmitted to the thread ends by turning the thread ends to untwist the thread ends up to the upstream from a section where the thread ends come in contact with the thread contact face 6.
