An apparatus for packaging yarn packages in plural layers in a cardboard box or a like container is disclosed. A plurality of yarn packages carried to a packaging station by a transporting carrier are grouped in several groups and, then, a group of yarn packages is received by a supporting means with sufficient intervening space between two adjacent yarn packages for easy mechanical handling. Then, the above-mentioned space between two adjacent yarn packages is contracted automatically while the group of yarn packages is carried to a station for transferring them into a cardboard box or a like container, so as to fix the disposition of the yarn packages in the arrangement of a square lattice on a partition plate disposed in the container. When a plurality of yarn packages have been disposed in one layer in the container an intermediate partition plate is utilized for covering and fixing the upper end of the bobbin of each yarn package in that layer and fixing the lower end of each bobbin in the succeeding layer. When the package contains a plurality of such layers, an upper partition plate is utilized to cover and fix the upper end of the bobbin of each yarn package in the uppermost layer. In the apparatus of the present invention, auxiliary mechanisms such as a partition plate feeding device, a pallet lifting device, etc., are preferably utilized.
