Endless Conveyor Belts

An endless conveyor belt is a type of conveyor belt that is manufactured as a continuous loop without any seams or joints. Unlike traditional conveyor belts that are made in long sections and then spliced or fastened together on-site, endless belts are a single, monolithic piece.

This seamless construction is their defining characteristic and the source of their key advantages, making them the preferred choice for applications requiring high precision, hygiene, and durability.

COLD MILL WRAPPER BELT

A cold mill wrapper belt is a specialized, high-performance belt used in the steel and metal processing industry. Its primary function is to securely and precisely wrap flat-rolled metal strips (such as steel or aluminum) into compact, cylindrical coils.

This is a critical, yet delicate, part of the cold rolling process. Unlike hot mills where the metal is at a high temperature, cold mills deal with metal at or near room temperature. This requires the wrapper belt to handle a hard, rigid, and sometimes abrasive material while preventing surface damage.

A corrugated sidewall conveyor is a specialized type of belt conveyor that is designed to transport materials at steep angles, including vertical (90°) inclinations. Its unique construction allows it to handle bulk materials in confined spaces and with high efficiency..

CATTERPILLAR BELTS

Usage:

This type of belt is a critical component in a machine known as a "caterpillar haul-off unit." The machine works with a pair of these belts—one on top, one on the bottom—that clamp down on a continuous product to pull it away from an extrusion die at a precise speed. This process is essential for:

  • Cable and Wire Extrusion: In the cable industry, extruded cables are passed between two flat caterpillar belts. The belts pull the cable uniformly, ensuring a consistent diameter and quality as it cools before being spooled.

  • Plastic Profile and Pipe Manufacturing: This is a major application. The belts are used to pull extruded PVC pipes, hoses, and other plastic profiles through the cooling and cutting processes. Their strong, even grip prevents the soft plastic from deforming.

  • Welding Rod and Tube Manufacturing: They are used to convey and pull continuous products like welding rods or various types of industrial tubing along the production line with precision.

  • Packaging and Winding: In some applications, they are used to drag, roll, and press layers of material, such as paper, in the creation of tubes and other packaging products.

Key Characteristics and Benefits in these Applications:

  • Precise Speed Control: The use of a pair of belts provides a strong, non-slip grip, ensuring a uniform and consistent pulling speed.

  • Damage Prevention: Because the grip is distributed over a large surface area, it prevents damage or marking on the surface of the extruded product.

  • Endless and Seamless: High-quality caterpillar belts are made as a single, endless loop without a seam or splice. This is crucial for preventing any "jump" or irregularity in the pulling motion, which could compromise the product's quality.

  • Usage of Caterpillar Drive Belts (in Heavy Machinery):

    These are the belts (V-belts, serpentine belts, etc.) found in the engines of equipment made by Caterpillar Inc., such as bulldozers, excavators, and generators. Their usage is for:

  • Powering Engine Components: These belts transfer power from the engine's crankshaft to various accessories, including the alternator, water pump, power steering pump, and air conditioning compressor

RIB TYPE CENTRE HOLES CONVEYOR

  • Suitability for specific materials: Ribbed belts are particularly effective for conveying materials that are prone to slippage, such as granular, lumpy, or packaged goods, especially on inclines.

    Center holes function

    • Drainage and Filtration: In applications like wet processing or dewatering, the holes facilitate the separation of liquids or contaminants from solids as they are conveyed.

    • Airflow and Cooling: For certain applications, holes can allow for better airflow, potentially aiding in the cooling of the transported materials or the belt itself.

    • Specialized Handling: Depending on the material and application, holes can also be used for specific handling tasks, such as vacuum conveying for delicate items.

    Essentially, a rib-type center hole conveyor belt is designed to:

    • Convey materials efficiently: The ribbed surface ensures secure and stable transport, even on inclines.

    • Address specific material handling challenges: The center holes address challenges related to draining liquids, separating contaminants, or providing specialized airflow.


CATTERPILLAR - CABLE BELT

A "Caterpillar cable belt" is a specialized type of industrial belt used in a process known as "haul-off." Unlike the continuous tracks on a bulldozer or tank (which is a different use of the term "caterpillar"), these belts are a key component in machinery used for the extrusion of cables, pipes, tubes, and other long, continuous products. The primary usage of these belts is to provide a consistent, high-friction grip to pull the product away from an extruder die at a controlled, stable speed. This ensures the final product has a uniform diameter, a consistent shape, and an accurate length.

1. Cable and Wire Manufacturing

This is one of the most common applications. In cable extrusion lines, a caterpillar haul-off machine uses a pair of these belts—one on top and one on the bottom—to grip the cable firmly. This process is crucial for:

  • Pulling extruded cables from the extrusion die.

  • Maintaining a constant line speed to prevent variations in the cable's diameter and overall quality.

  • Winding the finished product onto a spool or into a drum.

2. PVC Pipe and Plastic Profile Extrusion. In the plastic and PVC industry, a caterpillar belt system is essential for: Traction and Pulling: It provides the necessary pulling force to draw extruded PVC pipes and other plastic profiles (like window frames, door trims, etc.) through the cooling and cutting stages.

  • Preventing Deformity: The consistent and even grip of the two belts prevents the newly formed, soft plastic from deforming as it is being pulled.

3. Welding Rod and Tube Manufacturing: other continuous products, such as welding rods or various types of industrial tubing, these belts serve a similar purpose

  • Precise Conveying: They ensure the product moves at a precise speed along the production line.

  • Quality Control: The consistent movement and traction are vital for maintaining product integrity and quality throughout the manufacturing process.

  • Key Features and Functions:

  • Dual-Belt System: The belts operate in pairs, providing a strong and even clamping force from both the top and bottom of the product.

  • High-Friction Surface: The belts are typically made from a rubber or similar material with excellent abrasion resistance to provide a reliable grip without damaging the product.

  • Endless and Spliceless: Many high-quality caterpillar belts are manufactured as a continuous loop without a splice or joint. This is critical for preventing "jumps" or inconsistencies in the pulling speed that could compromise the product's dimensions.

  • Customization: They are often available with different surface textures (grooved, smooth, etc.) and levels of hardness (Shore hardness) to match the specific requirements of the material being extruded.
