An apparatus for providing batches of a mouldable, fibre-reinforced thermoplastic material matched to a moulding to be produced and accompanied by heating, wherein a free-flowing initial product of fibres and thermoplastic material-containing binders are heated as a strand and a matched batch is separated from the strand and supplied to batch further processing. The apparatus includes a melting device with a melting channel, through which the material to be processed is pressed as a continuous strand, as well as a cooling station.
