Balanced Spiral Woven Conveyor Belts

Balanced Weave Conveyor Belts are also known as spiral wire link conveyor belts, is the most commonly used belt for wire mesh conveyor belts.


PFM Screen’ Balanced Weave Conveyor Belts have been successfully used in the food industry, the heat treatment industry, the chemical industry and the glass industry, etc. Its simple design, the big range of dimensions (wire diameters and pitches) and the various ranges of belt materials are the main reason for its success.

Overview

    Balanced Weave Conveyor Belt is a stainless steel balanced woven belt with left and right-hand wound spirals, connected by crimped cross wires. At the sides of the belt, the cross wire is welded to the spiral wire. Balanced weave belts can be used for a virtually infinite number of applications. Ranging from super strong for conveying heavy loads over large widths or conveying very hot products to very dense weaves for small products, unsorted goods or products requiring stable support.


Balanced Weave Conveyor Belts can be executed with chains at both sides. The connection between the chains and the belt is mostly by means of extra cross rods going through the spiral of the belt and trough the chains. The spiral part of the belt will carry the product. The chains will drive and guide the spiral part. Driving this belt is easy by means of chain sprockets.


Balanced Spiral Woven Belts are manufactured in compliance with the latest food safety requirements for food processing equipment such as FDA, GMP and 1935/2004/EC. This ensures our customers a belt that is fit for use in the most demanding food processing applications.Spiral wirelink belts are suitable for a wide range of active food contact applications such as:Baking, Frying, Drying, Cooling, Freezing, Pasteurizing,etc.

Balanced Weave Conveyor Belt can be used in the temperature range of -50º to + 1350ºC. The length and width of the conveyor belt can be customized according to demand.

The stainless steel Balanced Weave Conveyor  Belts can additionally be equipped with edge plates and flights. The pins can be bent upwards in some belt types of the spiral wire link belts which will create a standing edge.


Features and Benefits

 High Temperature Resistance
Balanced spiral woven belts are ideal high temperature resistant mesh belts, capable of withstanding extreme heat up to 1150°C (dependent on material), making them suitable for annealing oven conveyor belts, lehr conveyor belts, and other heat treatment systems.

 Excellent Load Distribution
The interwoven spirals and cross-rods provide an even distribution of load across the belt width, ensuring long belt life under both light and heavy-duty applications.

 Open Mesh for Airflow and Easy Cleaning
The open structure promotes efficient air circulation and quick drainage—essential for cooling, drying, or baking. This also allows for easy cleaning, especially in wire mesh baking ovens belts and food-grade applications.

 Customizable Mesh Density and Structure
Available in standard, double, and compound balanced configurations, these belts can be tailored for precise product support or airflow needs. Options range from wide-open designs to close mesh for small or delicate items.

 Material and Edge Versatility
Can be made from stainless steel, carbon stee, nickel-chromium alloys, and more. Edge options include welded, hooked, laddered, and chain-driven, supporting both friction- and sprocket-driven systems.

 Durable and Low Maintenance
Balanced woven belts are engineered for longevity, offering high resistance to wear, thermal fatigue, and corrosion. Their robust construction reduces maintenance frequency and operational downtime.

 Compatible with Accessories
Supports side guards, flights, and chain edges, enabling inclined conveying, product separation, or containment—ideal for complex conveyor layouts.

 Proven Across Industries
From food processing to glass production, from metal heat treatment to packaging lines, these belts are trusted worldwide for their reliability and adaptability.

 Straight-Running and Self-Tracking
The symmetrical spiral design—featuring alternating left and right spirals—ensures smooth, straight tracking. This eliminates belt wander and reduces the risk of system misalignment, especially on long conveyor runs.


Belt Types

Balanced Spiral Woven Conveyor Belts are available in 4 types different versions. From  corrugated wirelink belt that is alternatively woven left and right to create a straight run to rod reinforced belt structure that is designed for applications that involve high temperatures. PFM Screen offers the following 4 types of belt configurations:


  • Standard Balanced Spiral Woven Belt
    The Standard Balanced Spiral Woven Belts consists of alternating left and right hand coils with each coil interconnecting with the next by means of a crimped cross wire.

  • Double Balanced Spiral Woven Belt
    Double Balanced Spiral Woven Belts is similar to standard balanced spiral but uses coil pairs of each handing intermeshing and then link by means of the crimped cross wire with pairs of intermeshing opposite hand coils on a repeat pattern down the length. This style allows for closer pitching of coils across the width for small product handling.

  • Standard balanced Spiral Woven Belt
    with straight cross wire

    The structure of this belt is similar to “Standard Balanced Spiral” but uses a straight cross wire with single interconnecting coils in a repeat pattern of left hand/right hand down the length. This assembly allows for a closer pitching of single coils across the width for small product handling.

  • Double Balanced Spiral Woven Belt
    with straight cross wire

    The structure of this belt is similar to “Double Balanced Spiral” but uses a straight cross wire with double intermeshing coils of each handing interconnecting by means of the straight cross wire in a repeat pattern of left hand/right hand coils down the length. This assembly allows for a closer pitching of coils cross the width for small product handling.

Edge Availability


  • Welded Edge
    This is the most common and economical edge finish.  With welding together of both the coil and crimp wires there are not cut wire ends.

  • Laddered Edge
    Less common than the welded edge the laddered edge is often used where welds are not desirable for the application.  It is also an option in applications where welding facilities are not available.  The belt edge is also smooth and allows more belt edge flexibility.  It is also more efficient in high temperature applications as the laddered edge is not under operational strain in use and therefore less prone to fracture.  Generally this edge finish is only available for meshes with a relatively large crimp wire pitch down the length.

  • Hook Edge
    Also less common than the welded edge type the hook edge is often used where welds are not desirable for the application.  It is also an option in applications where welding facilities are not available.  The belt edge is also smooth and allows more belt edge flexibility.  Generally this edge finish is only available for meshes with a relatively large crimp wire pitch down the length.

  • Chain Edge Driven Mesh
    Along with the above mesh edge finishes these meshes can be driven by side chains using cross rods which are located through the mesh coils and then through chains at the edges of the mesh.

Balanced Spiral Woven Metal Conveyor Belts for Industrial Product Processing, Transfer and Packaging Belts

Balanced Weave Conveyor Belts are the most versatile and widely used metal conveyor belts, thanks to their characteristics of true travel, good flexibility, excellent strength-to-weight ratio, flat surface and minimal maintenance. These belts are typically friction driven and are popular for conveying a variety of products, particularly those that are small or need a lot of support. Food processing spiral wire link conveyor belts are typically used in product transfer and in baking applications. Balanced Spiral Woven Belts can also be used in industrial product processing, transfer and packaging applications.
