The invention concerns a web-printed item (1,2) for a web-printed pair (3) of a sheet-fed chain (4), comprising:a longitudinal length (5);a height range (7);-a width range (9);a flat surface (11,12) for contact with a flat surface (13) in use in a flat chain (4);a rolling surface (14,15) for contact with another weighing piece (2,1) in use in a weighing set (3); andA frontal plane (16,17) facing the longitudinal plane (5) with an angle parallel to the radial direction (8) is called an azimuth angle (18,19),where, in the case of an azimuth angle (18,19) of zero, the longitudinal distance (5) is vertical on the corresponding forehead surface (16,17) and in the case of an azimuth angle (18,19) greater than zero, the corresponding forehead area (16,17) the extension in axial direction (6) of the rolling surface (14) is shorter than that of the flat surface (11). The weighing unit (1,2) is characterized mainly by the fact that the front surfaces (16,17) of the weighing unit (1,2) have an azimuth angle (18,19) unequally zero.A further reduction in noise emission is achieved by means of the proposed weighing unit, with only a small or no increase in the stress of friction contact with the cone pairs.
