Claims6
A process for producing a yarn end reserve on a cross-wound package which is carried on a conical package former having end portions extending beyond the side of the wound yarn package, the smaller end portion of the conical package former defining a cylindrical portion, the process comprising:
- unwinding the package to withdraw a length of yarn from the package;
- rotating the package in the normal winding direction;
- deflecting the withdrawn yarn onto the cylindrical end portion of the package former as the package is rotated in the normal winding direction causing the yarn to wrap around the surface of the cylindrical end portion;
- and deflecting the withdrawn yarn end over the side of the package for laying the withdrawn yarn end on the surface of the package.
