The cutting plate of a press for shaping sheets of paper or cardboard comprises a bottom beam receiving a support plate (1) on which a metal cutting plate (7) is placed, the support plate (1) has means for adjusting its position in a horizontal plane and means for fixing the cutting plate (7). The support plate (1), on a first side thereof, has at least one moving stirrup (15, 16), the said moving stirrup being adapted to take up a clamping position where it prevents the cutting plate (7) from sliding on the support plate (1) and an inoperative position where it enables the cutting plate (7) to slide on the support plate (1). The side opposite the first side and one of the adjacent sides are provided with at least one fixed stirrup (10, 11, 12, 13, 14) disposed so that portions of the edge of the cutting plate (7) can be slid into the said fixed stirrups and be gripped under the moving stirrups in the clamping position.
A blanking platen of a press for shaping sheets of paper or cardboard, comprising a bottom beam receiving a support plate (1) on which a metal cutting sheet (7) can be placed, the support plate comprising means for adjusting its position in a horizontal plane and means for fixing the cutting plate (7), characterised in that the support plate (1) on a first side thereof comprises at least one moving stirrup (15, 16), the moving stirrup being adapted to take up a clamping position where it prevents the cutting plate (7) from sliding on the support plate (1) and an inoperative position where it enables the cutting plate (7) to slide on the support plate (1), whereas on the side opposite the first side and on an adjacent side, the support plate comprises at least one respective fixed stirrup (10, 11, 12, 13, 14) disposed so that edge portions of the cutting plate (7) can be slid into the fixed stirrup (10, 11, 12, 13, 14) and be gripped under the moving stirrup (15, 16) in the clamping position.
A blanking platen according to any of the preceding claims, characterised in that each moving stirrup (15, 16) is mounted on a moving push rod which can be manually actuated to counteract a return force, enabling the moving stirrup or stirrups to rotate from the said inoperative position to the said clamping position.
A blanking platen according to any of the preceding claims, characterised in that under each moving stirrup (15, 16) the support plate (1) has a recess for receiving the said moving stirrup when in the inoperative position.
A blanking platen according to any of the preceding claims, characterised in that on each of its sides, the support plate (1) has means (2, 3), more particularly adjustment blocks bearing milled knobs (4, 5), for micrometric adjustment of the longitudinal position of the said edge of the support plate.
