    摘要: The invention relates to a grooved forming roll, which includes a rotably supported shell (20) comprising circular openings (21) arranged to be opened at least on the outer surface of the shell (20). In connection with each opening (21), formed on the outer surface there is a circular groove (22), which is arranged concentrically relative to the corresponding opening (21). In addition, on the outer surface a portion of the formed circular openings (22) extends to each opening (21) from each adjacent opening (21). The outer radius (r) of the circular groove (22) is arranged such that the number of necks (24), delimited by the adjacent openings (21) and their circular grooves (22) on the shell outer surface within the area of one circular groove (22), is greater than the number of the adjacent openings (21) of the corresponding opening (21).
