Method and device for loading an installation with fibres

Method according to any one of the preceding claims, characterised in that the actual pressure values which are measured in the pneumatic feeding installation are converted by a differentiation over time into a corrected actual pressure value, and the resulting difference, with a desired pressure value, is introduced into the regulating circuit.

Method according to any one of the preceding claims, characterised in that, for starting up the spinning room preparation installation, the regulating algorithm starts from a constant mass flow of fed fibre tufts.

Method according to any one of the preceding claims, characterised in that planned or unplanned fluctuating production amounts of at least one fibre-processing machine are processed in the regulating circuit.

Method according to any one of the preceding claims, characterised in that fluctuations in the pneumatic feeding installation through the determined fibre running time are introduced into the regulating circuit.

Method according to any one of the preceding claims, characterised in that the maximum amount of fed fibre tufts can be set manually.

Method according to any one of the preceding claims, characterised in that the desired pressure in the pneumatic feeding installation can be set manually.

Apparatus for feeding an installation with fibres, which installation is fed with fibre tufts, the fibre tufts are opened at least partially and fed by means of a feed apparatus to a pneumatic feeding installation, which guides the fibres into the reservoir of at least one fibre-processing machine, especially a flat card, roller card, opener or cleaner, characterised in that, by means of a regulator (X2) which is part of a regulating circuit into which the actual pressure values (p1) measured and further processed in the pneumatic feeding installation are introduced, and into which the mass flow ({dot over (m)}1) of the further processed fibres measured and further processed at at least one fibre-processing machine is introduced, the optimal operating point of the installation is determined by means of a regulating algorithm, and a signal (z) is passed to an actuator of the feed apparatus for regulating the amount of fibre tufts ({dot over (m)}2).
