Title: Twisted yarn break splicing - applies a twist to the broken end of the doubled yarn before splicing
Inventor: STAHLECKER HANS
IPC: D01H15/007
Filed: 1991-02-13
Abstract: To repair a yarn break at a twisting machine, where the broken end of the twisted yarn is spliced to the end of the doubled yarn drawn off the bobbin, the end of the doubled yarn is twisted before splicing.
