Abstract (en)
[origin: WO9116480A1] This process is used to optimize yarn quality and maintain it constant in the automatic mixing of bales of different quality. Bales of different quality (1a, ...1b, ...1n) are placed in the transport path (3) of the transfer element (4) of a yarn-transfer device (2) and a yarn sample is taken automatically from each bale (1k) processed by the yarn-removal element (4) and the sample automatically analysed in a measurement and control unit (5). The measured values obtained in this way are continuously compared by a programme in the measurement and control unit (5) with reference values, and the comparative monitoring carried out in this way is used to maintain the mixture parameters constant by controlling the yarn-removal device (2) to remove appropriate amounts of yarn from the various bales of different quality (1a, ...1k, ...1n).
