Therefore the timing unit 33 with driving group is taken to first lock in the embodiment of the timing of cold film transfer Stop bit is put in E1, wherein transfer film breadth 5 is directed to transfer gap 6 in guiding roller 35 from film in film guiding.Cause For film roller 35 is guided to be arranged to be connected with timing unit, thus shift the guiding of film breadth 5 shift gap 6 it The surface of pressing roller 3 is delivered in preceding such spacing, that is, obtains the expansion relative to guiding on approximate tangential Wrapping angle and the guiding for being derived from improvement.It is important in this that the surface of pressing roller 3 has relative to transfer film 5 More precisely say the friction of the reduction for being in dorsal part on pressing roller 3, forming carrier thin film of transfer film 5.

In addition realized in the case of film paths F2 by shifting the smaller of pressing roller 3 caused by film breadth 5 Wrapping angle, wherein film guide structure is into until extension on approximation at pressing roller 3 is tangential.Have proven to herein, When the smaller wrapping angle of the adjustment at pressing roller 3, for implementing when performing cold film and shifting into the fortune without timing It can be achieved to apply the simpler mode of production for covering quality with sufficient for line mode.

The displaceable arrangement for carrying the timing unit of driving group 33 for this reason is of use not only in introducing turn Move the operation simplified during film 5.According to the present invention in order in the fortune for the simplification shifted without the cold film in the case of timing Line mode equally takes timing unit in the second lock position E2 to.So transfer film 5 can be directed through timing unit simultaneously And transfer gap 6 is directed to by the film guiding roller of film guide device 14, wherein so carrying out at pressing roller 3 more It is appropriate to say tangentially guiding transfer film 5 by shifting gap.

In addition in order to which the method for operation film guiding for the simplification shifted according to Fig. 1 cold film can also be from timing unit 33 In guided on the film paths F3 similar with the second film paths F2 by one or more films of film guide device 14 Roller guides.Film breadth 5 is shifted herein according to Fig. 1 in a manner of coming out from timing unit 33 by film guiding roller 35 to be drawn It is directed at the one or more of the film guiding roller of film guide device 14.Turn by this way for the cold film with timing It can also have been realized for the method for operation of shifting and transfer film breadth 5 is approximately tangentially guided at pressing roller 3 by transfer seam Gap 6.

Such method of operation is favourable in a case where, i.e., when in the less timing stepping of implementation (Taktschritt) and in the case of the time of stopping occurred herein of transfer film breadth 5 film timing is carried out.By means of this The method of operation of sample can realize bigger machine speed and be achieved in the productivity ratio improved.
