Abstract: A system for moving a carriage along a guide comprises: at least one sliding block that slidingly connects the carriage to the guide; a control shaft associated to the carriage; a driving unit suitable for moving said control shaft in rotation; and rotary-translatory connecting means between said control shaft and said guide. The control shaft is movable between a working position wherein it is connected to said guide for moving the carriage by said driving unit, and an idle position wherein it is disconnected from said guide for free manual pulling of the carriage through said at least one sliding block.

Abstract: The invention relates to a method and a machine for aligning at least two flexographic printing plates on at least one printing cylinder. The method comprises the steps of capturing an image relating to a first plate, capturing the image relating to a portion of a second plate, reprocessing the image captured from the first plate so as to obtain a portion thereof corresponding to the image relating to the portion of the second plate, concurrently displaying said reprocessed image and the image captured from the second plate and aligning said two images.

Abstract: The present invention relates to a method for aligning at least two flexographic printing plates on at least one printing cylinder, which provides acquiring an image of a part of a first plate, memorising the acquired image, framing a part of a second plate, at the same time displaying the memorised image and the image relating to the part of the second framed plate in real time; and aligning the image framed in real time with the memorised image.
