Patent ID: 8156982

Claim:
An apparatus for transferring a transfer layer from a carrier film, which together form a transfer film, to a printing material, the apparatus comprising: at least one film module having at least one transfer film supply roll for storing and unwinding at least one transfer film web and a supply shaft for holding said at least one transfer film supply roll; a drive for driving said supply shaft; a transfer film guiding device for guiding the transfer film web from said supply shaft to a transfer nip along a film transport path, the transfer nip being formed by an impression cylinder and a film transfer cylinder for transferring the transfer layer to the printing material, by guiding the printing material through the transfer nip along a printing material transport path; and a collecting device for accommodating the at least one transfer film web guided through the transfer nip, said collecting device having at least one transfer film collecting roll for winding up the at least one transfer film web and a collecting shaft for holding said at least one transfer film collecting roll, at least said supply shaft being a friction shaft, said friction shaft being driven by said drive so that a transfer of a rotational movement of said friction shaft to said at least one transfer film supply roll is carried out via a frictional connection between said friction shaft and said transfer film supply roll which can be overcome by tensile forces of the transfer film web.
