A method for the cyclic production and continuous provision of a resin-filler mixture (9, 9') in the course of producing plastic moulded parts with or without fibres for reinforcing, wherein at least fractions (7, 7', 7"...) of the resin are pre-mixed as a pre-mixture (4, 4') and homogenised together with a filler and with or without fibres in at least one extruder (13, 13') into a resin-filler mixture (9, 9'), having the following features: a) the individual fractions (7, 7', 7"...) of a determined pre-mixture (4, 4') are dosed in a gravimetrically controlled manner into a mixing container for producing a pre-mixture (4, 4') under an admission pressure via dosing valves from various storage containers (6, 6', 6"...), b) wherein a weighing apparatus attached to the mixing container and an open-loop or closed loop control apparatus connected to said container sets and/or controls the quantity of every single fraction (7, 7', 7"...) of the pre-mixture (4, 4') during the gravimetrically controlled dosing of the individual fractions (7, 7', 7"...), c) wherein subsequently or simultaneously the individual introduced fractions (7, 7', 7"...) in the mixing container are mixed with a stirring apparatus into a pre-mixture (4, 4'), d) and said pre-mixture (4, 4') is transferred in a cyclic fashion to a dosing container after sufficient pre-mixing, e) and the dosing container continuously supplies the pre-mixture in a continuously dosed fashion at least to an extruder (13, 13') for producing a resin-filler mixture (9, 9') during the preceding method steps via a second weighing apparatus attached to the dosing container and an associated second open-loop or close loop control apparatus and a feed pump, f) wherein a further pre-mixture is produced in the mixing container during the continuous transfer of the pre-mixture to the extruder (13, 13'), g) wherein the continuous conveying from the dosing container to the extruder (13, 13') occurs in a gravimetrically or volumetrically controlled or regulated manner, h) and wherein the continuous extraction of the pre-mixture (4, 4') from the dosing container is changed over by means of the feed pump for this period to volumetric dosing during the cyclic transfer of the pre-mixture (4, 4') from the mixing container to the dosing container. a) the individual fractions (7, 7', 7"...) of a determined pre-mixture (4, 4') are dosed in a gravimetrically controlled manner into a mixing container for producing a pre-mixture (4, 4') under an admission pressure via dosing valves from various storage containers (6, 6', 6"...), b) wherein a weighing apparatus attached to the mixing container and an open-loop or closed loop control apparatus connected to said container sets and/or controls the quantity of every single fraction (7, 7', 7"...) of the pre-mixture (4, 4') during the gravimetrically controlled dosing of the individual fractions (7, 7', 7"...), c) wherein subsequently or simultaneously the individual introduced fractions (7, 7', 7"...) in the mixing container are mixed with a stirring apparatus into a pre-mixture (4, 4'), d) and said pre-mixture (4, 4') is transferred in a cyclic fashion to a dosing container after sufficient pre-mixing, e) and the dosing container continuously supplies the pre-mixture in a continuously dosed fashion at least to an extruder (13, 13') for producing a resin-filler mixture (9, 9') during the preceding method steps via a second weighing apparatus attached to the dosing container and an associated second open-loop or close loop control apparatus and a feed pump, f) wherein a further pre-mixture is produced in the mixing container during the continuous transfer of the pre-mixture to the extruder (13, 13'), g) wherein the continuous conveying from the dosing container to the extruder (13, 13') occurs in a gravimetrically or volumetrically controlled or regulated manner, h) and wherein the continuous extraction of the pre-mixture (4, 4') from the dosing container is changed over by means of the feed pump for this period to volumetric dosing during the cyclic transfer of the pre-mixture (4, 4') from the mixing container to the dosing container.
