<p>The printing cylinder is mounted between two points of two supports which are mounted by slots in a surface plate. A mobile assembly moves vertically to position an eye glass located on one side of the cylinder while the projector is emitting a luminous beam from the other side and supported on a U-shaped arm. The eyeglass is supported on a cross member which slides on vertical columns and is adjusted by a micrometer screw. An electronic probe provides position information for a display unit. The two columns are fixed at their lower ends to a horizontal base section which is slidably mounted on a base, forming a longitudinally mobile trolley. The base member can be locked onto the base plate by a screw and its position can be precisely adjusted.</p> |
