ABSTRACT:
A method of continuously introducing an impregnating liquid into a textile fiber arrangement, wherein the fiber arrangement is passed through a converging space formed by circumferential surfaces of a pair of discs and by lateral limiting walls for transforming the fiber arrangement into a fiber sliver, the liquid is supplied under pressure to the face sides of the discs, and a liquid film is formed on the face sides of the discs for supporting the discs by said liquid film. Further, the liquid is transported along the face sides of said discs to the circumferential surfaces into the converging space by rotating the discs, there is formed a coat of liquid surrounding the fiber arrangement passing through said converging space, and subsequently condensing the fiber sliver into a compact fiber sliver in an adjacent hydrodynamic pressure zone acting at all sides and pressing liquid into the fiber sliver in said pressure zone by passing the fiber sliver between the circumferential surfaces of the discs.
