2 PCS 4x8 7-Digit Backward Jump Roman Numbering Machine for Printing Press

The 4×8 7-Digit Backward Jump Roman Numbering Machine is a mechanical numbering component designed for numerical printing applications. The unit features seven individual mechanical digit wheels arranged in a compact assembly for seven-digit serial numbering and corresponding jump-number printing applications. This version uses a backward jump configuration. Mechanical numbering machines can differ in numbering direction, jump mode, digit count, and mounting dimensions, so the original machine specification should be checked before ordering. The compact metal body includes mounting sections on both sides for connection with the corresponding printing machine assembly. Each package contains 2 pieces, making the set suitable for printing shops, maintenance technicians, repair departments, and spare-parts inventory.
