The PETRA 10-Digit Auto Numbering Machine is a heavy-duty, self-inking metal stamp engineered for high-volume document control, manufacturing serialization, and transactional tracking. This robust office tool automates the process of repetitive sequence labeling by shifting numbers forward mechanically with each stamp press.
Core Specifications & Mechanics
