FIELD: printing. SUBSTANCE: grip has two parts. One part is installed for turning relative to the other part. Free ends of both part of grip interact to hold printed matter. First part of grip is installed through ball joint in support part fixed on rotating hollow shaft. Compression spring is placed between support and first part of grip installed in support through ball members. Compression spring exerts pressure on first part of grip when support is in closed position. Ball joint is displaced rearwards relative to turnable axle of support. As a result, elongation of arm of first part of grip is provided directed backwards to create favorable conditions for operation of lever and to form heavy clamping forces in zone of free end of first part of grip, if compression spring is installed.
