Abstract: A printing machine for printing on a web includes a plurality of guide rollers for guiding the web through a simplex and a duplex path in the printing machine. The duplex path is adjacent and laterally shifted with respect to the simplex path. An apparatus for turning or laterally shifting the web and transfer the web from the simplex path to the duplex path includes four rollers. 90° twists are present between rollers 1 and 2 and between rollers 3 and 4. Rollers 1 and 4 are substantially parallel, and rollers 2 and 3 are substantially parallel. Rollers 1 and 4 are substantially at right angles to rollers 2 and 3.

Abstract: A method for turning or laterally shifting a web in a printing machine includes guiding the web successively around four rollers. Roller 2 is rotated with respect to roller 1 by about 90°, so that a strand of the web extending between the first and second rollers performs a first twist by about 90°. Rollers 1 and 3 are substantially parallel so that the strand of the web extending between the second and third rollers is straight. Roller 4 is rotated with respect to roller 3 by about 90°, so that a strand of the web extending between rollers 3 and 4 performs a second twist by about 90°.

Abstract: A high speed photofinishing apparatus for reading information/data from a photosensitive filmstrip and for writing data on a magnetic layer contained on the filmstrip. The apparatus comprises at least one device for reading information/data from the filmstrip and a magnetic write head for writing information/data on the magnetic layer at a predetermined location. The write head is positioned with respect to the at least one device for reading a distance sufficient for allowing sufficient computational time needed for processing the information/data so that it can be magnetically written on the magnetic layer at the predetermined location.
