A device for driving a stamping foil over a path through a stamping machine is disclosed herein. The driving device comprises two foil-introduction chain-like elements and a drive member coupled to the foil-introduction chain-like elements for driving the foil-introduction chain-like elements notably through a platen press of a stamping machine. The driving device further comprises at least one first load-measurement device comprising a first detector configured to measure a parameter indicative of the load applied by the drive member for driving the foil-introduction chain-like elements in a first direction, the at least one first load-measurement device being connected to a stamping-machine control unit configured to stop the driving by the drive member when the parameter indicative of the load applied by the drive member and measured by the first detector crosses a threshold.

The invention concerns a device for unrolling a strip () for a stamping machine () that allows an accumulation of the strip to be stamped () under a pre-unrolled form between at least one stamping spool () and a plate press () of the stamping machine (), so characterized in that the device for unrolling a strip () comprises: The invention also comprises a stamping machine () so configured as to place on each sheet the gilded or metallic film of at least one strip to be stamped ().

Device for unwinding strips and machine for stamping elements in sheet form

A holding device () for a succession of sheet-shaped elements circulating in a processing machine () along conveying path T. The holding device () has two series () of a plurality of suction members (). At least one series of suction membersextends along and is movably mounted parallel to the transport path T of the sheets, between a retracted position and a deployed position. Each series is in an array, parallel to the transport path and the suction members are arranged spaced apart alongside one another, so that the array of members extend perpendicular to the conveying path T of the sheets and the suction members () of each series () are transversely offset relative to the suction members () of the other series ().

The blanking station of a diecutting press comprises an upper cradle for a blanking device and gripper bars for conveying the sheets in progress. This upper cradle includes devices for the removable mounting alternately of a blanking device or of a delivery device of non-severed sheets. At least one cam for opening grippers of the said gripper bars, and the cam is mounted in a removable manner.

Blanking station of a diecutting press

A converting press for paper or cardboard sheets including a waste stripping station and/or a blanking station with a pull-out chase ( ). A pair of horizontal transverse rails ( ) supports an upper stripping tool for a waste stripping operation, or a blanking tool for a blanking operation. The first rail ( ) is fixed relative to the chase and the second rail is movable in a longitudinal direction. The profile of the rails allows receiving and maintaining in an operational waste stripping position, a pull-out chase of an upper tool or an upper stripping board, and/or blanking board for blanking operation.
