Product Description

The Grey Rubber Folder Gluer Belt with Single-Row Through Holes is a high-performance conveying accessory specifically engineered for folder gluer machines in the printing and packaging industry. Crafted from premium grey rubber, this belt features a precise single-row through-hole design, which works seamlessly with the vacuum suction system of folder gluers to achieve stable, accurate paper feeding. Its grey rubber surface offers excellent friction and wear resistance, ensuring no paper marks or damage during conveying, while the single-row through holes are evenly spaced to provide consistent vacuum adsorption—effectively preventing paper drift, double feeding, and misalignment, thus enhancing the efficiency and quality of box-folding operations.

Designed for durability and reliability, this belt combines flexibility with high tensile strength, adapting to the continuous operation of folder gluers and maintaining dimensional stability even under long-term high-speed running. It is a cost-effective and essential consumable for modern packaging production lines, suitable for both standard and custom folder gluer models.

Applications

Automatic folder gluer machines (both flat-bed and rotary types) for corrugated boxes, cartons, and gift boxes production.
Precision feeding of thin cardstock, coated paper, offset paper, and light-weight corrugated board in high-speed box-folding lines.
Packaging production lines requiring stable vacuum adsorption, such as food packaging, cosmetic packaging, and electronic product packaging.
Replacement of old or worn belts for folder gluer models from major manufacturers (e.g., MBO, Bobst, Heidelberg), ensuring compatibility and seamless integration.
Scenarios where single-row hole adsorption is required to avoid paper damage—ideal for printed or coated paper that is sensitive to pressure.

Technical Features & Advantages

1. Single-Row Through-Hole Design

The precise single-row through holes are evenly punched using water cutting or precision stamping technology, with smooth, burr-free edges to prevent paper tearing. The single-row layout is optimised for vacuum adsorption, ensuring consistent suction force across the belt width—effectively fixing the paper in place during high-speed conveying and eliminating misalignment.

2. Premium Material Performance

Made of high-quality grey rubber (CR/NBR), the belt offers excellent wear resistance and oil resistance, capable of withstanding long-term friction with paper and resistance to corrosion from printing inks and glues. The reinforced polyester canvas skeleton ensures low elongation and high dimensional stability, preventing belt stretching or deformation during operation.

3.Easy Installation & Long Service Life

The endless hot vulcanised joint ensures a seamless connection, avoiding paper jamming at the joint and enabling smooth high-speed operation. The belt is easy to install and maintain, with a long service life that reduces the frequency of replacement and lowers production costs.
