A b s t r a c t The invention relates to blending of individual fibre components in accordance with the properties of a required intermediate product such as a card silver, or a required end product such as a yarn. The blending process is as follows: fibre bales (2) are combined Into component groups and the fibre components in the groups are accurately supplied by metering devices (11) to a blender, in which the components are homogeneously mixed. The product from the blender is then cleaned in a cleaning station (60) and delivered for processing to a card (63). After leaving the card, the sliver is tested in a colour-testing device (65) and the corresponding signal 18 delivered to a control system (7; 7.1; 7.2; 44) which primarily controls the component blend and secondarily is also corrected by a colour system so that the primary blend control is altered until the colour at the outlet of the card again coincides with the colour in the card silver. The card silver is also tested for fibre fineness (MICRONAIR) using the fibre-fineness testing device (66), and a corresponding signal is delivered to the aforementioned control system. The aforementioned component blend is also adjusted by means of this signal, if the fineness deviates from a preset value. A third signal (81) comes from the card control system (64). This signal indicates the output (kg/h) to the aforementioned control system, in order to control the amount delivered by the extraction devices (20, 23).
