The printing form on the printing drum of the machine bears an image in the form of a multi-line text. A counterpressure element can be moved to an operative position to effect transfer of the whole text onto whole-page sheets or transfer of individual lines or line groups to smaller-format cards or slips. The counterpressure element is moved by an activatable moving unit. A sheet feeding unit is activatable for feeding whole-page sheets to the printing location. A card feeding unit is activatable for feeding smaller-format cards to the printing location. A diverting unit is activatable for diverting printed whole-page sheets directly to the delivery station and smaller-format cards to a branch path in which they are turned over and then deposited at the delivery station in the printing sequence. A marking unit is activatable for providing routing markings on the various sheets and cards. A programmable control system is automatically operative for activating preselectable ones of the aforementioned activatable units preselectable numbers of times in preselectable sequences.
In a rotary duplicator machine of the type provided with a rotary printing drum, an image transfer location, a printing form mounted on the drum and bearing a transferrable image in the form of a text comprised of a plurality of successive lines, a counterpressure element and activatable means operative when activated for moving the counterpressure element into and out of operative position to effect transfer of the whole text, individual lines or groups of lines to sheet material transported between the printing drum and the counterpressure element, infeed rollers located upstream of the image transfer location for feeding sheet material to the image transfer location, activatable sheet feeding means operative when activated for removing whole-page sheets onto which the entire text of the printing form is to be transferred from a stack of such sheets and feeding such whole-page sheets to the infeed rollers, activatable card feeding means operative when activated for feeding to the infeed rollers cards of smaller format than the whole-page sheets and onto which only preselected portions of the text on the printing form are to be transferred, a delivery station downstream of the printing drum, an outfeed transport means for transporting printed whole-page sheets and smaller-format cards from the printing location towards the delivery station along an outfeed path having two branches, the first branch leading directly to the delivery station, the second branch including a turnover means for turning over printed cards to cause them to be deposited at the delivery station each one printed-side-down upon the back of the previously printed card, adjustable diverting means operative when activated for diverting cards transported along the outfeed path into the second branch, and activatable marking means located intermediate the printing drum and delivery station and operative when activated for providing routing markings on the printed whole-page sheets and smaller-format cards, in combination therewith, programmable control means automatically operative for activating preselectable ones of said activatable means preselectable numbers of times in preselectable sequences.
