Abstract
In an apparatus for compressing and automatic introduction of a fibre strand into a feed nip: an opening is formed as a longitudinal slot (12, 12a, b12"a) extending from the outlet port (15) of the nozzle channel (7;7") in the longitudinal direction thereof and in a plane extending substantially perpendicular to the plane (E--E) of the feed nip (1; 1"). The contour of the insertion nozzle (6, 6") adjacent its outlet end on both sides of the longitudinal slot (12, 12a, b; 12"a) is of a shape (9, 10;9") conforming to the contours of the components (2, 3; 2", 8"a), particularly rollers (2, 3) defining the feed nip (1; 1").
