Do You Know The Application of Carrier Rope?

The Application of Carrier Rope on Paper Machine

In the paper making industry, carrier rope play a crucial role in ensuring the stable and continuous transport of the paper web, guiding it through various sections such as forming, pressing, drying, calendering, and reeling. Consequently, carrier rope requires high strength, low elongation, wear resistance, high temperature resistance, anti-static properties, and non-stick performance to ensure stable and efficient paper transfer.

To meet the demanding conditions of modern paper production, carrier ropes are typically manufactured from high-performance synthetic materials such as polyester, aramid, or blended fibers. The carrier rope surfaces undergo a specialized treatment developed by Sun Hong, which simultaneously enhances grip and effectively prevents paper adhesion, thereby ensuring smooth and reliable paper sheet transport even in high-humidity and high-temperature environments.

Core Function of Carrier Rope

• Pulling the paper: During paper breakage, roll change, and startup, narrow paper is pulled through various roller groups to quickly establish full width operation.

• Stable tension: Maintain even tension at the edges of the paper, reducing paper breakage and wrinkles.

• High temperature resistance: Suitable for high temperature environments of 100-180 ℃ in the dryer section.

• Wear resistance and fatigue resistance: Continuous high-speed operation (300-1500m/min), long service life.

Material of Carrier Rope

Aramid (DuPont/Kevlar)

• Advantages: high strength (breaking 8 – 9g/d), low elongation (≤ 3%), high temperature resistance (280 ℃), wear resistance and aging resistance.

• Applicable: high-speed paper machine (>800m/min), dryer section, long-distance paper guiding.

Structure type of Carrier Rope

Carrier Rope with Core

Structure: Multi strand (8 strands/12 strands) weaving, without an inner core.

Features: Soft, easy to bend, slightly high elongation (4% -5%).

Applicable: short distance, low tension, medium low speed.

Carrier Rope without Core

Structure: Inner core (aramid/polyester monofilament)+outer layer woven.

Features: Low elongation (≤ 3%), high stiffness, stable tension, and not easily relaxed.

Applicable: High speed, long-distance, dry section (preferred for mainstream).

How to Choose Carrier Rope

• Forming and press section: medium speed → with core and without core type, 10-12mm; high speed → aramid belt core, 12-14mm.

• Dryer section: aramid core+coating, 14-16mm (high temperature resistance, low elongation).

• Calendering/winding: Polyester/aramid blend, 12-14mm (wear-resistant, anti-static).

• High speed paper machine (>1000m/min): Full aramid core, 16mm+coating.
