Mechanism for cutting and distributing portions of sheet, particularly pap er towels, comprising at least one cylinder (9) which can rotate around its axi s in a supporting structure (1, 2, 3) and drag an end portion (8) of at least one sheet, inside said cylinder (9) being arranged one or more movable blades (28) whic h can protrude outside the cylinder (9) for cutting said end portion (8) of th e sheet and are fixed to a shaft (26) suitable for rotating around an axis parallel to the longitudinal axis of the cylinder (9), wherein said shaft (26) is provided with at least a first member (30) which protrudes from one side of the cylinder (9) and can be rotated for an arc of a circumference by at least a second member (25 ) which shifts in a direction parallel to the longitudinal axis of the shaft (26) of the movable blades (28) and rotates around this axis, the rotational-translation al motion of this second member (25) being synchronized with the rotatory motio n of the cylinder (9). The present invention also relates to a paper towel dispenser comprising said mechanism. |
