HC-138

HC-138 envelope and paper sack sealing machine is a kind of high-speed, high-quality Chinese-style small-size envelope and paper sack maker of our factory by assimilating leading technologies from abroad based on independent innovation. The mechanical properties and product quality are equivalent to those of imported devices, so the machine is provided with a high cost-performance ratio and the latest technical norms. The machine features bottom paper feed technology, extending stability of paper distribution and reliability. Technology prevents paper reading under suspension. The attached air admitting roller provides two traverse folding mechanism and simplistic and yet practical longitudinal folding mechanism, thus it could accomplish bottom sealing and envelope tongue folding accurately. The traction and sealing components are equipped with electronic counting and grouping devices with preset functionality.
