  • Patent number: 11020958
    Abstract: A foil reel mounting device for supporting a reel of stamping foil in a supporting module. The device includes a support having a recess to receive an axle of the reel of stamping foil. A retaining element mounted on the support and arranged to move between a closed position, in which the retaining element retains the axle of the reel in the recess, and an open position, in which the retaining element releases the axle of the reel from the recess. The retaining element is biased towards the closed position. Also, a supporting module has at least one foil reel mounting device and a stamping machine includes a supporting module or at least one foil reel mounting device. A method for loading and unloading a reel of stamping foil with such at least one foil reel mounting device is also disclosed.

  • Patent number: 10906763
    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).

  • Patent number: 10093506
    Abstract: A braking device 1 is provided for a tape reel mounted rotatably about its axis. The braking device 1 includes two rotating members 10, 20 rotationally coupled with the reel, and a selection member 30 configured to cooperate by friction selectively with either one of the rotating members 10, 20 by moving the selection member to engage one or the other rotating member for friction braking.

  • Publication number: 20180257366
    Abstract: A foil reel mounting device (10; 40) for supporting a reel (2) of stamping foil (3) in a supporting module (1). The device is fixed to the supporting module (1). It includes a support (11; 41) having a recess (16; 46) to receive an axle (7) of the reel (2) of stamping foil (3). A retaining element (12; 42) mounted on the support (11; 41) and arranged to move between a closed position, in which the retaining element (12; 42) retains the axle (7) of the reel (2) in the recess (16; 46), and an open position, in which the retaining element (12; 42) releases the axle (7) of the reel (2) from the recess (16; 46). The retaining element (12; 42) is biased towards the closed position. Also, a supporting module (1) has at least one foil reel mounting device (10; 40) and a stamping machine (100) includes a supporting module (1) or at least one foil reel mounting device (10; 40). A method for loading and unloading a reel (2) of stamping foil (3) with such at least one foil reel mounting device (10; 40) is also disclosed.

  • Patent number: 9849706
    Abstract: A device 300 for printing a succession of sheets, includes a platen press 310 for depositing colored or metalized film on each sheet by stamping between a stationary platen 320 and a movable platen 330. A heating element 340 brings a stamping tool integral with the stationary platen 320 to a given temperature for a stamping operation. The heating element 340 is displaced between an operating position between the stationary platen 320 and each stamping tool associated with that platen 320, and a maintenance position in which the heating element is outside the platen press 310.
