Abstract
An extruder with at least one bore, in which an extruder shaft is arranged to be rotatingly driven, has a device for introducing a glass fibre strand. To this effect the shaft is provided with an adjustable throttling device, upstream of which starts out an impregnating channel which opens again into the bore downstream of the throttling device seen in conveying direction, i.e. into a mixing zone, in which the fibre strand is cut into fibre sections. An especially intense impregnating of the fibres of the fibre strand is thus achieved.
