| description | The invention relates to an impregnating device for impregnating at least one quasi-endless fibre material with a plastic material which is melted at a corresponding process temperature, having at least one fibre supply channel a having a fibre feed to supply the quasi-endless fibre material to the impregnating device, and at least one plastic supply channel having a plastic feed separate from the fibre feed to supply the plastic material to the impregnating device separately from the fibre material, the at least one fibre supply channel and the at least one plastic supply channel being separate at least in some portions and opening out into a common impregnation cavity to impregnate the quasi-endless fibre material with the supplied and melted plastic material, characterised in that the impregnating device has a backflow-blocking region in which die fibre supply channel has, at least in some portions, an S-shaped profile which is formed by two curves with opposing curve directions, between which the fibre supply channel is joined with the at least one plastic supply channel so that a coalition channel portion is then formed. |
