    摘要: Method for packaging in a carton full size yarn packages by a yarn producing machine provided with a plurality of yarn package producing units. A predetermined number of full size yarn packages are firstly doffed from the corresponding spindles of the yarn producing machine at once by means of the bobbins chucks which are displaceable as one group, and each doffed yarn package is wrapped separately by a film bag while holding by the corresponding bobbin chuck. Next the yarn packages wrapped with the corresponding film bags are deposited at once into a space of a carton by displacing the bobbin chucks, and after releasing the gripping of the yarn packages by the respective bobbin chucks, these bobbin chucks are displaced to their standby positions. The pitch between each two adjacent bobbin chucks is changed from the spindle pitch to the pitch for depositing the yarn packages into the carton, just before the operation for wrapping each yarn package by a film bag or the operation for depositing the wrapped yarn packages into the carton. The above-mentioned operation is repeated for carrying out the doffing operation for all spindles of the yarn producing machine.
