There is described a method of increasing the output of a transfer film () upon embossing, in particular hot embossing, wherein the transfer film () has a carrier film () and a transfer layer portion () which is releasable from the carrier film (). During a first embossing operation first regions () of the transfer layer portion () which are arranged removed from each other at a spacing a are transferred by means of a first embossing tool from the transfer film () onto at least one substrate (), wherein first openings () are produced at the spacing a in the transfer layer portion () of the transfer film (). After the first embossing operation the transfer film () is wound up after the first embossing operation and fed to at least a further embossing operation.

Method of increasing the output of a transfer film upon embossing and apparatus suitable for same

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.
