Abstract: This severing device (1) includes an upper pressing member (2), a pile support part (4) having a plurality of conveying members (10) for conveying the pile in a conveying direction (X), a lower pressing member (6) arranged under the conveying members (10). The conveying members (10) are juxtaposed in a transverse direction. Two juxtaposed conveying members can be parted. The lower pressing member (6) has: i) two adjacent lower plates (6.1, 6.2) that can be moved apart, and ii) a lower translation actuator (6.3) for moving the lower plates (6.1, 6.2) so as to cause the severance slot (2.0) between juxtaposed conveying members to coincide with a frangible line in the plate.

Abstract: A method for supplying plate elements to a machine for processing the plate elements, from an initial pile of elements, the method includes: pushing a first batch of plate elements, from the top of the pile, downstream until the first batch comes at a storage capable of storing the first pushed batch, and simultaneously, displacing the storage downstream over a distance corresponding to the length of the first batch to separate the first batch from the pile; and thereafter transferring the elements of the first batch one after the other to the machine.

Abstract: A method of adjusting a machine (1) for printing plate elements (12) equipped with at least one rotary impression cylinder (27) includes the steps of measuring a speed of the element (12, 13) passing through the machine (1), generating an operating signal (34) as a function of the measured speed and a tangential speed of the cylinder (27), and adjusting an operating speed of the machine (1) as a function of the signal generated so that the operating speed of the machine (1) is such that the speed of the element (12, 13) is substantially equal to the tangential speed of the cylinder (27).

Abstract: A device for positioning a plate element (7a, 7b, 7c) in an infeed station (2) of a machine for treating the element (1), fitted with a conveyor (8, 9), gripping the element (7a, 7b, 7c) which is found in a predetermined intermediate position, and carrying the element (7a, 7b, 7c) in a rated running into successive processing stations (3, 4, 6). The device includes a holding device (18) for temporarily holding the element (7a, 7b, 7c), the holding device moving longitudinally alternatively (A) from an upstream position to a downstream position, and vice-versa, to pick up the element (7a, 7b, 7c) in a rear position and bring it to the intermediate position, and to return empty. A motor (23) moves the holding device (18) longitudinally, from the upstream position to the downstream position, and vice-versa, as a function of the rated running. A detector (27) detects a rear longitudinal position in which the element (7a, 7b, 7c) is found, and emits a position signal.

An unloading device (7) unloads the elements (1a) from the initial pile (3). An intermediate storage device (16), stores the unloaded elements (1) in the form of an intermediate batch (19) and is positioned downstream of the unloading device (7), a conveyor device (18) for conveying the elements (1) from the storage device (16) to the infeed station, and a shingling device (21) for shingling the elements (1) and being positioned downstream of the storage device (16).

Abstract: A method for registering at least two colors for a machine for printing plate elements equipped with at least two printing units: printing marks of different colors in spaced pairs on edges of the plate elements; detecting position errors between different marks of possibly the same color and comparing the position with respective theoretical relative positions; adjusting operation of the printing units to have both marks of a color overlie.

Abstract: Method of positioning thin flat objects within a processing machine comprising an inserter for positioning these objects in a plurality of gripper members belonging to a conveyor drawing them discontinuously through successive stations. This method consists in calculating, for each of the gripper members, variations in the positioning distance of these members relative to a reference position, assigning these variations to the respective gripper members, and incorporating them into a primary procedure of the controller to improve the positioning of the thin flat objects in the gripper members.

Abstract: An independent motor/reductor drives a conveyance device that feeds a converting press. The converting press includes a number of stations including a feeding station, a converting station, a waste stripping station and a delivery station. The conveyance device services the stations and includes two endless gripper bar chains to convey sheet material through the converting press. A transverse drive shaft drives the conveyance device under the control of the independent motor/reductor. The independent motor/reductor provides motion trajectories for the conveyance device that are independent of, but synchronized with, the serviced stations. The arrangement improves throughput, reduces machine wear and results in a simplified design.

Abstract: This universal ejection tool (1) for the waste from a blanking press for cutting out sheet elements, particularly for a press for cutting sheet elements such as paper or cardboard intended for the production of packages, comprises a frame (2), the top part of which is equipped with a plate (10) perforated with a plurality of holes (11) uniformly distributed. The bottom part of said frame is provided with a plate (12) identical to the plate (10) and of substantially identical dimensions to those of the frame (2). Said plate (12) is also perforated with a plurality of holes (13), which are perfectly aligned with the holes (11) in pairs on vertical straight lines. Said plates (10, 12) are separated in the inner space of the frame (2) by a separating means. The vertical pairs of holes (11, 13) are traversable by ejection needles (30), which are simply held therein by a spring effect.
