Abstract
An improvement in cutters used in the field of paper manufacturing consisting in that the support-bearing for the knife is connected to a raising and lowering device through a structure elastically deformable and able to impart elastically opposing movements to the knife. These movements are essentially motions of torsion which allow compound movements thereby providing continuous engagement between the knives and the counter knives during rotation. Said elastic structure consists of at least one rectangularly shaped elongated blade formed of steel.
