Abstract (en)
[origin: EP0362538A1] The invention relates to the mixing of individual fibre components on the basis of properties of a requisite intermediate product, for example a card band, or a requisite final product, for example a yarn. <??>This mixing is carried out by combining fibre bales (2) to form component groups and by adding the fibre components of these groups in exact amounts by means of metering devices (11) to a mixer in which these components are mixed homogeneously. <??>The product of the mixer is subsequently cleaned in an opening room (60) and thereafter transferred to a card (63) for processing. <??>After the card, the card band is tested in a colour tester (65) and the appropriate signal is transmitted to a control (7; 7.1; 7.2; 44) which primarily controls the component mixture and secondly is corrected by such a colour signal, should the primary mixture control be varied correspondingly, until the colour in the card band is correct again at the outlet of the card. <??>The card band is then tested for fibre fineness (MICRONAIR) by means of the fibre-fineness tester (66) and an appropriate signal is transmitted to the abovementioned control. The abovementioned component mixture is also changed in response to this signal if the fineness differs from a predetermined design value. <??>A third signal (81) comes from the card control (64). This signal transmits the output (kg/h) to the abovementioned control, in order to control the stripping output of the stripping devices (20, 23). <IMAGE>
