Abstract

A film-embossing apparatus with a hot-embossing device which has a heated embossing stamp. With the formation of a contact pressure, a transfer layer, arranged on a carrier film, of a hot-embossing film is transferred to a surface of a workpiece. The hot-embossing device has control inputs and outputs. The film-embossing apparatus has an industrial robot with control inputs and outputs. The control inputs and outputs of the hot-embossing device and of the industrial robot are connected to a control unit. The industrial robot is formed such that it guides the workpiece to the hot-embossing device, positions the workpiece on the embossing stamp, guides the workpiece past the embossing stamp, and guides the embossed workpiece away from the hot-embossing device. The industrial robot can also position the hot-embossing device on the workpiece.

A film-embossing apparatus for transferring a transfer layer

arranged on a carrier film, of a hot-embossing film to a surface of a workpiece with a hot-embossing device which has a heatable embossing stamp,
wherein the hot-embossing device has control inputs and outputs, and
wherein the film-embossing apparatus has an industrial robot with control inputs and outputs, and
wherein the control inputs and outputs of the hot-embossing device and of the industrial robot are connected to a control unit, and
wherein the industrial robot is formed such that it:
guides the workpiece to the hot-embossing device,
positions the workpiece on the embossing stamp or guides it along the embossing stamp, and
guides the embossed workpiece away from the hot-embossing device, and
wherein the hot-embossing device has a first film-guiding lever with a first film-guiding roller, arranged upstream of the embossing stamp, and a second film guiding lever with a second film-guiding roller, arranged downstream of the embossing stamp, the first and second film-guiding levers cooperating with the industrial robot, and
wherein the industrial robot is further adapted to detach the carrier film from the transfer layer transferred to the workpiece.
