Mounting arrangement of the bars supporting the grippers in a mapmaking or security-paper printing machine, wherein each bar consists of a pair of parallel tubular rods and is supported at its opposite ends on two transport chains slidable along two parallel fixed guides, each bar end being mounted on a pair of pins fixed to the chains and projecting therefrom towards said bar. Between said bar ends and said pairs of support pins there is interposed an intermediate support, formed by two elements apt to slide telescopically one in respect of the other in a direction parallel to the sliding plane of the chains, one of said elements, in the form of a plate, comprising two transversal bores to house said pins of the chain, while the other element, in the form of a slide, is fixed to an end of the bar and is slidably mounted on said plate.
