Patented rear suction paper feeder with independent servo control for paper feeding, simple and easy to maintain.
CM450B Automatic Case Maker (Photoelectric Positioning)
The high-stability workhorse for long-run production. The CM450B is designed for high-volume, continuous manufacturing of standard-sized covers.
It uses a reliable Photoelectric Positioning system and a robust standard straight-edge folding structure (Front Tucking + Straight Plate), ensuring maximum stability and efficiency for dedicated, non-irregular jobs.
Max. Size: (e.g., 450 x 800 mm)
Core Tech: Photoelectric (Optical) Positioning.
Key Feature: Optimized for long-run, standard straight-edge covers.
Benefit: Extremely reliable and cost-effective for mass production of standard book covers.
