Method for restoring the operation of a yarn twist apparatus following a yarn break

A method for restoring the operation of a twist apparatus which imparts a prescribed twist to a yarn following a break in the yarn as it travels between a twist spindle of the twist apparatus and a wind-up package of the twist apparatus, the method comprising:

• drawing off a twist yarn end from the wind-up package;
• securing the drawn off twist yarn end at a fixed securement point once the drawn off twist yarn end has been drawn off the wind-up package to an extent such that the drawn off twist yarn end comprises a portion with an intact twist turn;
• cutting the drawn off twist yarn end at a cutting location selected such that a sufficient extent of the twist yarn end is available below the fixed securement point for subsequently interconnecting this twist yarn extent with a spin yarn end of the yarn from the twist spindle;
• interconnecting the twist yarn end from the wind-up package with the spin yarn end of the yarn from the twist spindle by a selected one of knotting the yarn ends to one another and splicing the yarn ends to one another;
• re-commencing the operation of the twist spindle;
• and
• re-commencing the operation of the wind-up package in a time-delayed manner relative to the re-commencing of the operation of the twist spindle with the time delay being such that the prescribed twist which the completed twist yarn is to have has propagated through the location at which the yarn ends have been interconnected to one another to the fixed securement point.
