with the nip k and is located on the level of the outlet opening 31a of the guiding channel 31 of the sliver funnel 30 it delimits the rear end of the prong shaped guidance segments 32 33 and marks the beginning of an approximately rectangular surface 31b visible in fig3 which supports the oval outlet 31a of the channel defined in one direction as being approximately parallel with the plane 90 connecting the axes of rotation 100a and 100b of the calendar disks the width of this inclined surface 31b is approximately equal to the distance between the inner surfaces 32a 33a of the prongs 32 33 in order to provide the best possible guidance for the emerging fiber sliver the straight forward edge 32e 33e of the guidance segments 32 33 prongs is shown in fig2 a in such a manner that it continues backwards at its outer end with two different curvature gradients 32d so that the prongs 32 33 become larger in the rear area than in the area close to the nip k if the prongs taper to a point the danger of breakage is higher in the forward area and for this reason care should be.
