A feeding element intended for refiners with two opposed refining means (11, 12), one of which is stationary and one rotary, which are provided with refining elements (14, 15), which between themselves form a refining gap (17) with a refining zone (16) for working lignocellulosic fibrous material. A feeding device (20, 22) is located centrally inside the refining gap (17). The feeding element (30) is intended to be placed on the rotary refining means (12) in the refining gap (17} directly outside the feeding device (20, 22). The feeding element (30) is formed with at least one feeding bar (31), where the upper edge (33) of each feeding bar projects out on at least one side of the bar.
