Abstract: A hot foil stamping press (10) comprises a platen press (16), with a supporting plate (22) comprising a base plate (26) and a compensating plate (28) being rotatably attached to the base plate (26) for switching between an operating position and a makeready position and a hook element (38) comprising a base part and a top part being arranged at an angle relative to the base part. The hook element (38) is rotatably attached to a door (30) of the platen press (16) by a fixation axle for switching between a releasing position and a securing position of the hook element, wherein the top part retains the compensating plate (28) in its makeready position when the hook element (38) is in its securing position.

Abstract: A platen press with a press toggle mechanism (43) having a driving member (14) and a press toggle column (44). The press toggle column (44) comprises a driven member (38), a first toggle lever (46) assigned to the driven member (38) and a second toggle lever (48) assigned to the driven member (38). The first toggle lever (46) has a first contact surface (50) and the second toggle lever (48) has a second contact surface (52). Both toggle levers (46, 48) contact each other via their contact surfaces (50, 52), and wherein both contact surfaces (50, 52) are convex-shaped.

Abstract: A method for checking and correcting the position of a blank (10) that includes closing the folded right-hand and left-hand flaps (17, 18) of the blank, which are positioned one above the other in an overlapping portion, checking the position of the right-hand edge (13) and of the left-hand edge (14), and comparing the position with a predetermined position in order to determine a positional deviation, if the positional deviation exceeds an admissible deviation value, and before the glue sets, fixing of the central flap (19), then holding the upper face of the right-hand flap and of the left-hand flap by a suction cup (21, 23, 24, 26), and correcting the position of the left-hand flap (18) and/or of the right-hand flap (17) by moving the suction cup (21, 23, 24, 26).

Abstract: A very compact play-free bearing unit includes a bearing that runs without play while having a reasonably large play when assembling and during disassembly of the bearing unit from its axle. The bearing unit uses three bearings, one of which is mobile, and thanks to a preloading mechanism the play is removed when loaded. Thanks to an amplification lever, the preloading unit is able to function either with a pneumatic actuator or with a hydraulic actuator.

Abstract: A system for supporting a reel of stamping foil (2) that is mounted rotatably, includes: two flanges (9, 9′) connected to the shaft of the reel (2, 2′) that is positioned between the flanges, each flange having a rotary shaft extending outward of the reel; two end walls (7, 7′) mounted spaced apart on a guide surface (3′), each wall end having at least one upwardly oriented notch (10, 10′) arranged to receive the shaft of each flange (9, 9′); and a brake (13) which cooperates with and slows the rotation of the reel (2).

Abstract: A method for protecting a unit for converting a web substrate to limit a jam of the substrate inside the unit, the unit converting the substrate when the unit is stopped, in a packaging production machine: the steps of: detecting at the outlet of the unit that the converted web does not come out; stopping a motor of an infeed arrangement to prevent the substrate from entering the unit; stopping a motor of a feathering drive; and simultaneously stopping the machine, and guiding the substrate to an accumulation storage.
