A balanced weave conveyor belt is built from alternating left- and right-hand wire spirals joined by cross rods. Changing the spacing, wire size and material allows the same belt family to serve quite different jobs, from supporting small food products to carrying metal parts through a furnace.
The starting point is simple: what must the belt carry, and what happens to the product on the conveyor? That helps determine how open the mesh should be, which material to use and how the belt should be driven.
Whether you are designing a conveyor, replacing an old belt or improving a production line, you can begin with the information you already have.
1. Selecting a Balanced Weave Belt for a New Conveyor
If you already have a belt drawing or specification, send it to PFM Screen with the quantity required. We can work from your selected mesh, material and drive arrangement when reviewing the enquiry.
If you are still choosing, the following points will help you decide what matters for your process.
Choose the mesh around your product
For baking, cooling or drying, consider how much support the product needs while leaving space for air to pass through. For frying or washing, consider product retention alongside the passage of oil or water.
Standard balanced weave is a useful starting point for many applications. Where small or delicate products need closer support, double balanced weave is an option to consider: its paired spirals allow a closer arrangement across the belt width. The actual opening still depends on the selected pitch and wire sizes.
For example, a belt carrying baking trays can be selected around the tray support points. Small parts resting directly on the mesh need attention to the gaps between the wires. These two jobs may call for different meshes even when the conveyor widths are the same.
PFM also offers crimped and straight cross-wire versions. You can leave that choice to the specification review; a product photo and its approximate dimensions are enough to start discussing the mesh.
Standard Balanced Weave
A starting point for a wide range of product sizes and processes.
Double Balanced Weave
Paired spirals allow closer spacing for small-product support.
Match the material to the process
For food conveying, frying and washing, stainless steel options such as 304 and 316 are commonly considered. The choice depends on the product, process liquids and cleaning conditions. For furnace duty, the alloy needs to be selected for the operating temperature, furnace atmosphere and load.
Tell us the normal process temperature and whether the belt contacts water, oil or cleaning chemicals. For a furnace, include any atmosphere information you have. We can then recommend a material for that duty rather than ask you to choose from a long alloy list.
Choose the drive with the conveyor design
Balanced weave belts can use three drive arrangements:
-
Friction drive: a roller drives the belt through contact with the mesh. This is a common arrangement for balanced weave belts.
-
Positive mesh drive: matched sprockets engage the mesh directly. This is available for selected compatible mesh specifications.
-
Chain edge drive: sprockets drive chains on the two sides, with cross rods connecting the chains and mesh.
If your conveyor designer has already chosen the drive, share that arrangement. If it is still open, we can discuss the belt and drive together. Chain edges are an option where the conveyor is designed for them, rather than an upgrade every belt needs.
Add edge features only where the product needs them
Welded edges are a common finish. Hooked or laddered edges are also available for suitable constructions. These edge details can be settled when the belt specification is prepared.
If loose products need containment, ask about edge plates. If an inclined section needs help carrying the product, flights may be worth considering. A sketch of that part of the conveyor will help us discuss the arrangement.
2. Replacing an Existing Balanced Weave Belt
If your old belt worked well before wearing out, matching its original specification is usually the best starting point. You do not need to repeat the selection process for a new conveyor.
Send an existing drawing, belt specification or previous order description if available. For balanced weave belts, the matching details include the spiral and cross-rod pitches, their wire diameters, material and edge arrangement, along with belt width and length. We can help identify these from the records or sample you provide.
No drawing or mesh code?
Start with a clear mesh photo, a belt-edge photo and the approximate width. A photo of the drive is particularly useful if the belt runs on sprockets or side chains. We will explain which measurements are needed next; a small sample can help with details that are difficult to measure.
Customers who prefer to measure first can use our Balanced Woven Belt Measuring Guide.
3. Improving a Belt That Does Not Suit Your Process
If the current belt is causing a problem, describe that problem first. The useful change may be quite specific:
-
Small products fall through: review the clear opening and whether a closer mesh or double balanced construction would provide the support needed.
-
Airflow or drainage is restricted: review a more open specification alongside the support the product still needs.
-
Products escape at the sides or move on an incline: consider whether edge plates or flights suit the conveyor.
-
The belt wears or fails too soon: share photos of the affected area and the operating conditions so we can review the material, mesh and how the belt is running.
Changing from plastic modular or polyester mesh to metal?
A balanced weave belt may be worth considering when the process calls for a metal conveying surface, particularly for heating applications. Tell us why you want to change and send a conveyor photo or drawing. We can review suitability and explain any drive or support changes involved before you decide to order.
Start with Your Product, Drawing or Existing Belt
You do not need a complete mesh specification to make an enquiry. Send PFM Screen what you have: a drawing for a new conveyor, details of an existing balanced weave belt, or photos showing the problem you want to solve.
Include what you convey and the operating temperature, if known. We can help narrow down the options and set out the proposed specification for you to confirm.
