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).
Claims17
A system for supporting a reel of stamping foil in an unwinder module, in which the reel is mounted rotatably, the system comprising:
- two flanges connected to and spaced apart to receive and hold the reel between the flanges, each flange having a respective rotary shaft extending outward of the reel;
- an unwinder configured to unwind the reel of stamping foil;
- two ends mounted on guides, each end having an upwardly oriented notch located and arranged to receive the shaft of a respective one of the flanges so that the rotary shaft may rotate along with the flange, while the shaft is in the notch;
- and
- a braking device, separate from the unwinder, and configured to cooperate with and to brake rotation of the reel,
- wherein the braking device includes a disk brake including at least one brake caliper configured to act on the brake disk connected to one of the flanges.
