ABSTRACT:
An apparatus is disclosed for doffing and inserting empty cores on an automatic winder having core holders each clamping and freeing cores by assuming two prescribed positions, said apparatus being comprised of a position holding mechanism for holding cradle parts of winding units, a forwarding mechanism for arranging a package in a direction adapted for taking it off, a package take-off mechanism for taking off the package from the core holder, a package receiving mechanism for receiving the package so taken off, a yarn severing and holding mechanism for severing a yarn on a path from a bobbin of the winding unit to the package and carrying the yarn end to the core holder part, a core inserting mechanism for inserting an empty core over the core holder and returning the core holder to the winding up position and a core supply mechanism for supplying empty cores to the core inserting mechanism, so that successful doffing can be achieved regardless of the size and type of yarn packages, e.g. cheese-type packages or cone-type packages.
