A spreading unit for a creel basket of a textile machine, with - a carrier part that can be connected to a base carrier via a base surface and - a jaw part that can be connected to a clamping jaw via a bottom surface, such that the carrier part and the jaw part are resting against one another via a carrier part running surface (9a, 9b) and a jaw part running surface (9a, 9b), which are aligned correspondingly obliquely to the base surface and bottom surface in such a way that an adjustment of the jaw part directed parallel to the base surface and bottom surface and in the direction of the running surface relative to the carrier part causes a change in distance between the bottom surface and base surface, and the carrier part running surface (9a, 9b) and the jaw part running surface (9a, 9b) have a course curved around a first curvature axis extending parallel to the carrier part running surfaces/jaw part running surfaces (9a, 9b) and in the direction of adjustment in such a way that the jaw part can perform a lateral pendulum movement transversely to the direction of adjustment relative to the carrier part, characterised in that the carrier part running surface (9a, 9b) and the jaw part running surface (9a, 9b) each has a first running surface section curved around the first curvature axis and a second running surface section curved around a second curvature axis, with the first and second curvature axes running parallel to one another and opposite the running surfaces opposite to one another at the same distance from the carrier part running surfaces/jaw part running surfaces (9a, 9b) and a plane spanned by the curvature axis running perpendicular to the bottom surface and the base surface. - a carrier part that can be connected to a base carrier via a base surface and - a jaw part that can be connected to a clamping jaw via a bottom surface, such that the carrier part and the jaw part are resting against one another via a carrier part running surface (9a, 9b) and a jaw part running surface (9a, 9b), which are aligned correspondingly obliquely to the base surface and bottom surface in such a way that an adjustment of the jaw part directed parallel to the base surface and bottom surface and in the direction of the running surface relative to the carrier part causes a change in distance between the bottom surface and base surface, and the carrier part running surface (9a, 9b) and the jaw part running surface (9a, 9b) have a course curved around a first curvature axis extending parallel to the carrier part running surfaces/jaw part running surfaces (9a, 9b) and in the direction of adjustment in such a way that the jaw part can perform a lateral pendulum movement transversely to the direction of adjustment relative to the carrier part, characterised in that the carrier part running surface (9a, 9b) and the jaw part running surface (9a, 9b) each has a first running surface section curved around the first curvature axis and a second running surface section curved around a second curvature axis, with the first and second curvature axes running parallel to one another and opposite the running surfaces opposite to one another at the same distance from the carrier part running surfaces/jaw part running surfaces (9a, 9b) and a plane spanned by the curvature axis running perpendicular to the bottom surface and the base surface.
