Abstract: An automatic doffing and donning apparatus is disclosed for replacing a plurality of full bobbins which are mounted on winding spindles disposed parallel to each other on a yarn processing machine with a plurality of empty bobbins which are mounted on a bobbin reservoir plate disposed along and in front of the winding spindles. The apparatus comprises: a movable frame which is horizontally movable along both the yarn processing machine and the bobbin reservoir plates; a full bobbin doffing device mounted on the movable frame for doffing the full bobbins formed on the winding spindles and transferring them to the bobbin reservoir plate, and; an empty bobbin donning device mounted on the movable frame.

Abstract: 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.

Abstract: A plurality of yarn packages are stably held by a pair of protector plates in parallel and non contacting condition to each other so as to form a unit package. The yarn packages are covered with a sheet of film as a whole or separately at a position inside the protector plates. At least one unit package may be packaged in a cardboard box. In a preferable process for making the unit package, a series of successive operations, such as a first protector plate supply, a first film supply, mounting of a predetermined number of yarn packages on the first protector plate by way of the first film, a second film supply on the combined body of the yarn packages with the first protector plate, sealing of the first and second films for wrapping the yarn packages, a second protector plate supply, binding of the first and second protector plates by tapes, packaging at least one unit package in a cardboard box, are successively and intermittently carried out when items are displaced along an assembling conveyer line.
