ABSTRACT:
An optical transmission device for use on an apparatus for disposing a sleeve in encircling relation on an article unit is disclosed. Signals are sent and received between two data handling devices monitoring the machine. The first data handling device is positioned on a rotating portion of the apparatus and the second data handling device is positioned on another portion of the apparatus independent of the rotating portion. The optical transmission device comprises a first optical fiber element attached at a first end to the first rotating data handling device. The first element has an inner and an outer portion wherein the inner and outer portions are concentric. A second optical fiber element is also included and is attached at a first end to the second data handling device. The second element has an inner and an outer portion wherein the inner and outer portions are concentric and correspond to the inner and outer portions of the first element. The first and second elements each have second ends with the second ends facing each other with inner and outer end portions in correspondence with one another and positioned co-axial with the rotation axis of the rotating portion of the apparatus so that there is a gap between the second ends.
