Abstract: A belt (10) for a fiber web machine has an inner surface (11) and an outer surface (12). A plurality of parallel dewatering grooves are arranged in a first direction (D1) on the outer surface (12) of the belt (10), each dewatering groove having a width. A first dewatering groove (21) has shallow portions (30) having a first depth (32), and deep portions (40) having a second depth (42), which first and second depths (32, 42) are determined from the outer surface (12) of the belt (10) in a depth direction, wherein the first depth (32) is smaller than the second depth (42).
