A substrate-feeding device has at least two acceleration devices, which are arranged one beside the other, beneath a storage region, and having a framework and a lifting frame, which lifting frame can be moved relative to the framework. The at least two acceleration devices are arranged for movement jointly with one another, and with the lifting frame. Each of the acceleration devices has at least one body of rotation, which is driven via a common shaft which has at least two shaft portions arranged one behind the other. Directly adjacent shaft portions are arranged in a state in which they are connected in each case, via a coupling. There are subassemblies provided which each have a deflecting device, a shaft portion and at least one transporting belt and which are each one of fastened on the lifting frame, and are arranged for movement jointly with the lifting frame and are connected to one another by virtue of their shaft portions being connected via couplings to form the common shaft. The invention also relates to a sheet-processing machine.

A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus 200 is configured to upgrade an installed corrugated board processing machine (e.g., 10) and includes a feed table surface 210 for boards (e.g., 2) having drive wheels (222W, 224W, 226W) in an initial variable velocity zone 220 which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone 230 which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder 200 also includes a controller 300 configured to receive predetermined velocity signals from the host machine 10 and generate (i) a first initial variable velocity control signal for initial variable velocity zone 220 and (ii) a second velocity control signal for second velocity zone 230 in response.

The destacker apparatus (1), comprises: a succession of conveyors (10, 11, 12) arranged inclined relative to the horizon, each comprising a mobile surface (S) for receiving and supporting articles (J, K) carried upwards by the conveyors (10, 11, 12); and a device for varying the pressure of a fluid (2). The surface (S) of the conveyors (10, 11, 12) has through holes and the pressure varying device (2) is fluid dynamically connected to this surface (S).

The invention relates to an installation for printing and die-cutting laminar bodies, which comprises a digital printing station (1) for printing at least one face of the laminar bodies, and a die-cutting station (2) for die-cutting the laminar bodies coming from the digital printing station (1), comprising first conveying means (3) for moving the laminar bodies (P) positioned between the digital printing station (1) and a redirection station (5), and second conveying means (4) for moving the laminar bodies between the outlet of the redirection station (5) and the die-cutting station (2), The digital printing station defines an axial direction of travel and the die-cutting station (2) defines an axial direction of travel that is perpendicular to the axial direction of travel of the laminar bodies in the digital printing station (1), such that an L-shaped path of the laminar bodies (P), viewed in the plan view, is defined.

A device for feeding sheet products into a thick sheet feeding machine including an insertion gantry, a feed carriage sliding on rails. The device includes an insertion head configured as a gantry. The insertion head includes a crosspiece and support legs positioned on the rails and a system of suction cups located in the crosspiece through a forward movement mechanism allowing the system to move. The device includes an insertion module moving vertically on guides of the insertion gantry, a base for placing the sheets, and an alignment control device for aligning the sheets with respect to the insertion module. The sheets are suctioned by the suction cups, which are moved by the forward movement mechanism in the direction of the insertion gantry.

An insertion assembly for the continuous and automated feeding of laminar elements into a graphic printing station without the involvement of roller elements in the process, allowing the distance between the laminar elements in question to be adjusted such that adjacent laminar elements may be positioned very close to each other regardless of their length. Said assembly comprises an insertion device (1) that includes a rotating belt system on which the laminar elements (3) can be moved horizontally, and suction means, with the insertion device (1) connected to a stacking area (4) and; a pulling device (2) that includes a rotating belt system on which the laminar elements from the insertion device (1) can be moved, and suction means, with the pulling device (2) connected to a graphic printing station, said pulling device adjoining the insertion device (1) in a direction of forward motion.
