It uses the spokes structure which has better water cutting characteristic,and the surface is smooth so that it can avoid residues of paper fiber.The spokes is less 50% than ordinary cylinder mould,and it can achieve the minimum water resistance,at the same time it is adjustable so it can prevent the loosening of the rod and housing,at the last time it makes the strength of cylinder mould more higher and operation more flexible with control of quality and innovation of technological structure.
