ABSTRACT:
The invention relates to an apparatus for forming a sliver with a first regulated drafting arrangement (10) with several pairs of rollers (11, 12, 14) for the regulated drafting of the fibre mass (8) supplied to the drafting arrangement, with the fibre fleece (28) delivered by the drafting arrangement being joined and supplied to a measuring member (32) from where the measured fibre material is thereafter supplied to a second drafting arrangement (40) and with the autoleveller device (35, 52, 21) of the first drafting arrangement (10) intervening in a regulating manner in the drive of the first drafting arrangement (40) in order to compensate fluctuations in mass on the basis of the signals issued by the measuring member (32) by including a predetermined setpoint value.
Various regulating and control devices are known in practice in order to obtain a high-quality sliver. In order to detect and compensate short-wave and long-wave fluctuations in mass in a simple way an apparatus is proposed, with the second drafting arrangement (40) being provided with a control device (35, 50, 48) for compensating short-wave fluctuations in mass, which device intervenes in a controlling manner in the drive of the second drafting arrangement (40) on the basis of the signals issued by the measuring member (32).
