Abstract: A hot-stamping device (1) is described, having a stamping device (2) for transferring a transfer layer (15u) disposed on a carrier layer (15t) of a hot-stamping foil (15) onto a substrate (14). The hot-stamping device comprises a heatable stamping roller (11) and a counter-pressure roller (12), between which a stamping gap (16) is realized, in which a stamped substrate (17) is realized, and comprising a separating device (3), disposed downstream, for separating the carrier layer (15t) from the stamped substrate (17). The separating device (3) has a separating element (20), which is realized as a bar-shaped hollow body, disposed on which there is a supply for a compressed gas (21). At least one longitudinal edge of the separating element (20) is realized as a perforated separating edge (20k) having outflow openings (20a) for the compressed gas (22), for the purpose of realizing a gas cushion between the carrier layer (15t) and the separating element (20).

Abstract: There is described a joining device (1) comprising a stamp which can be moved up and down between a lower working position and an upper loading position. For example a hot embossing film (14) and a substrate (13) arranged under the hot embossing film (14) can be arranged between the stamp and the support table (12). The support table (12) is mounted pivotably about two pivot axes which are perpendicular to each other and which are perpendicular to the axis of movement of the stamp (11) and is pivotable by means of adjusting devices (18) about the two pivot axes, wherein the stamp (11) forms a rigid support in the working position. Alternatively the stamp (11) is mounted pivotably about two pivot axes which are perpendicular to each other and which are perpendicular to the axis of movement of the stamp (11) and is pivotable by means of adjusting devices (18) about the two pivot axes, wherein the support table (12) forms a rigid support in the working position.
