    摘要: The pressure-retaining device or clamp acts on the roll or log adjacently to the cutting plane and may be adapted to various diameters of the material being processed; for each path of advance of the rolls or logs (B) and on each side of the cutting plane, it comprises: a pair of symmetrically curved flexible strips (12, 14) projecting from enclosing supports (9A, 10; 7A, 10) and having end portions able to move according to the variation in the diameter of the roll, and a strap (22) fixed to elastic return holders (24A) and adjusting holders, said strap surrounding the pair of strips (12, 14) so as to vary their geometry in relation to the variation in the diameter of the material being processed.
