Abstract

An improved roll cover 4 used to cover a roll 2 for use in the press-section or forming section of paper, pulp and board making machines. The roll cover 4 has a plurality of bores 6, 12, the bores having substantially equal cross-sectional areas. In one embodiment the bores comprise through-bores 12 and blind-drilled holes 6, whereby each through-bore 12 is not immediately adjacent another through-bore 12 and is surrounded by an even distribution of blind-drilled holes 6. A circumferential groove 8 may be provided in the surface of the roll cover 4 which interconnects the bores.
