Method and Device for Hot Stamping

摘要

The invention relates to a method for hot stamping at least part of at least one band-shaped stamping foil (10, 20) onto a band-shaped substrate (30), as well as a corresponding hot stamping device. The substrate (30) to be stamped is brought together with one stamping foil (10, 20) of the at least one stamping foils (10, 20). The substrate (30) and the stamping foil (10, 20) resting thereon are guided along the periphery of a first heated stamping roller wherein, in a first stamping, a first stamping layer is stamped onto the substrate (30). The once-stamped substrate (30) is guided away from the first stamping roller and again brought together with the same or a further stamping foil (10, 20) of the at least one stamping foils (10, 20) after the first stamping roller in the direction of travel (33) of the substrate (30). The once-stamped substrate (30) and the stamping foil (10, 20) resting thereon are guided along the periphery of a second heated stamping roller wherein, in a second stamping, a second stamping layer is stamped onto the substrate (30). Finally the twice-stamped substrate (30) is guided away from the second stamping roller.

1. A method for hot stamping at least part of at least one band-shaped stamping foil onto a band-shaped substrate, wherein
the substrate to be stamped is brought together with one stamping foil of the at least one stamping foils, the substrate and the stamping foil resting thereon are guided along the periphery of a first heated stamping roller wherein, in a first stamping, the substrate and the stamping foil resting thereon are pressed against one another and against the heated surface of the first stamping roller by at least one first pressure roller arranged at the periphery of the first stamping roller and a first stamping layer is stamped onto the substrate, the once-stamped substrate is guided away from the first stamping roller and is again brought together with the same or a further stamping foil of the at least one stamping foils after the first stamping roller in relation to the direction of travel of the substrate, the once-stamped substrate and the stamping foil resting thereon are guided along the periphery of a second heated stamping roller wherein, in a second stamping, the substrate and the stamping foil resting thereon are pressed against one another and against the heated surface of the second stamping roller by at least one second pressure roller arranged at the periphery of the second stamping roller and a second stamping layer is stamped onto the substrate, and the twice-stamped substrate is guided away from the second stamping roller.
