What is a woven belt?
When you search for ‘woven belt’ there are two results you may find, and this can be confusing. Firstly, you have woven belts that are used in fashion. Secondly, you have woven belts that are used in the conveyor belt industry.
This common misconception in search results can make finding a woven belt manufacturer extremely frustrating for procurement and manufacturing teams who are looking to find highly respected solid woven belt manufacturers.
That being said, the woven belt used in the conveyor belt industry is a type of conveyor belt that is predominantly used the in biscuit/cracker manufacturing industry.
Types of woven conveyor belts
To make matters more confusing there are two types of woven conveyor belts. These are:
The difference between these two types of woven belts are the raw materials from which they are made from. Depending on the type of woven conveyor belt material, the industrial from which the belt is used may differ.
What are solid woven conveyor belts made from?
Solid Woven Conveyor belts are traditionally made from cotton yarn. Cotton conveyor belts, is a solid woven conveyor belt that is used traditionally in tea and biscuit production.
However, solid woven belts can be produced using nylon and polyester materials, also. Some conveyor solutions require a cotton-nylon blend.
This solution is used to achieve the three key requirements of a conveyor belt; long-lifespan, durability and moisture regain. This combines the ability of a cotton conveyor belt to absorb moisture and coherently ‘pull’ and release’ dough throughout the biscuit conveying process, with the high durability and longer lifespan of the nylon conveyor belt.
Synthetic woven conveyor belts are made from polyester, nylon, glass fiber, etc. and these types of belts also vary depending on the industry they serve. For example, nylon, which falls within the Thermoplastic conveyor belt family, can be used across chemical, medical and food production. Whereas polyester is used to create an air slide conveyor belt and is used in pneumatic conveying solutions.
How are woven conveyor belts used in biscuit manufacturing?
Within the biscuit and manufacturing industry there are two key stages in which the woven belt is during biscuit production.
Specifically, these stages are; the pre-oven stage where the dough has been made, the biscuits have been ‘marked’ and shaped and are ready for cooking, and the post-oven cooling stage.
During the post-over stage a solid woven belt is used to help filter air from underneath the biscuit to allow for equal cooling of the biscuit. It is imperative during the ‘cooling’ process of biscuit manufacturing that belts with high air permeability are used.
The detail is in the weaving of the conveyor belt. Belts for biscuit manufacturing can be made seamless and vary in ply depth and weave size. The traditional form of weaving for air permeable conveyor belts is Warp and Weft, however, various weaving methods can be implemented to suit the requirement for air penetration into the biscuit during post-oven cooking.
Types of weaves for woven conveyor belts
There are three key weaves for woven conveyor belts; standard, twill and broken twill. More information on the specifics of these weaves can be found in our guide to rotary moulder belts.
The weaves in woven belts must not be mistaken for the way in which metal conveyor belts are manufactured. For woven conveyor belts, the need for the weave is specific to the requirement of the industrial belt.
Depending on the material, and purpose, the weave to match will vary. Ultimately, the weave used is specific to either the need for; high durability and long-lifespan for the conveyor belt, high air penetration through the belt, or moisture retention, which is a requirement for food production conveyor belting.
How are woven conveyor belts used in pneumuatic conveying?
In pneumatic conveying the type of woven conveyor belt used is the air slide conveyor belt.
This particular conveyor belt is located in between the blower and air chamber in the pneumatic conveyor, and is used to efficiently transport pulverized material (referred to as ‘bulk powder’) over a long distance in a seamless and fluid motion.
The belt is kept within an enclosed solution and air is pushed through the weaves of the air slide belt to help transport the material through the conveying solution.
Air slide belts are a fantastic solution for pneumatic conveyor systems as they can be put through extreme conditions in order to transport materials at damaging temperatures with little to no damage through wear and tear of hot and cold rough pulverized material.
Woven Conveyor Belts
Cotton Conveyor Belts are our specialty, and can be used across all food production verticals due to their durability and long-life span.
Nylon belts are part of the thermoplastic conveyor belt family. They are used in industries where their hygienic properties are needed.
Solid Heavy Duty Belt
Our in house specialty renders us the unique ability to form heavy conveyor belts. Belts from 6mm to 16mm, and in 4000 GSM to 14000 GSM. These belts can endure pressure up to 75 Mpa with coefficient of friction greater than 0.4.
Our belts can be made with blended yarns that we would design to ensure your material would be transported seamlessly.
Some of the Industries our Conveyor Belts Serve
Similarly to biscuit production, the tea industry uses woven conveyor belts for the conveying purposes of leaf-to-bag production of the teabag.
As like the pharmaceutical industry, chemical manufacturing and production uses thermoplastic belts due to their hygeinic properties.
Flower can be transported using our non-stick thermoplastic belts that are absent of sticking properties and are easy-to-maintain.
