Eye-Flex^® belt without spacers

Eye-Flex^® has a standard construction based on a straight modular form. It is designed and built without spacers or perpendicularly welded under wires. This allows excellent flow-through in applications where no cross support is required. Eye-Flex^® is often used in food processing for its flat conveying surface, open mesh configuration, and ease of cleaning. Eye-Flex^® without spacers is also easily repaired with minimal cost.

Eye-Flex^® belt with underwelded wire spacing

Eye-Flex^®belting with underside welded wires provide the largest range of available gap widths, up to 50mm. One, two or three wires can be welded to the underside of the links, depending on the belt pitch and application requirements. Underwelded wire spacing should be considered on applications where hygiene and sanitation are critical. The underwelded wire eliminates the potential bacteria traps under the spacers, springs, rings and sleeves. This configuration makes cleaning and sanitation easy and more efficient.

Eye-Flex^® belt with rings as spacers

This versatile variation of Eye-Flex^® uses rings between the wires to increase the belt gap. By increasing the belt gap, more air will circulate around the bottom of the product. Increasing the product exposure to this additional air flow improves the efficiency of your process. The gap is set by one or more rings placed between adjacent links on the cross rod. The gap width is determined by the number and thickness of rings used.

Eye-Flex^® belt with springs as spacers

Springs help create a more dimensionally stable belt in heating or freezing applications. These belts are more dimensionally stable because the wires are able to move on the cross rod. Springs also expose a large proportion of the connecting rod for improved cleaning and sanitising. The gap width is secured by springs placed on the cross rod between adjacent links. Permanent fixing of the wire links does not occur with this method. They are held in relative position by compression of the springs.

Example #1

At Wire Belt we undertook a number of capital projects in the lead up to the Olympics, but there is none more unusual than the Eye-Flex® belt being used to clear the waterways around the Olympic Park. Wire Belts’ involvement with this project dates back to November 2006. The Canal and River Trust already had a weed clearing boat, and fundamental to its’ operation was the use of Eye-Flex type wire link belting.

In February 2007, the Canal and River Trust visited Wire Belt to discuss damage and maintenance problems that they were experiencing with belting from their existing supplier. Wire Belts’ John Warters was able to offer the solutions.

By changing its’ construction, the belt was made more resilient to damage and by re-engineering the boat, to use multiple narrow belts, utilization was improved. From an original belt life of two years the new belt, with about 20% repair and replacement, lasted for five years.

On May 23, 2012 the Canal and River Trust, with funding from the Environment Agency, launched two new weed boats that will service London’s waterways during the Olympics and beyond. The rivers and canals in East London formed a backdrop to the London 2012 Games, and keeping them clean and weed-free was more important than ever.

The belts for the new boat were supplied from Wire Belts’ factory, in Northern Germany, directly to the German boat builder.

Over 70 million dollars were invested in regenerating East London’s waterways, creating a wonderful legacy that stretches far beyond the summer of 2012. Rivers and canals are a prominent feature of the Olympic park.

Example #2

Eye-Flex® belting from Wire Belt, along with Flat-Flex® belting for less demanding situations, is used in a number of weed and debris applications. These include removing leaves from water channels at fish farms and in protecting small-scale hydro-electric generation installation from debris.

The picture here is of an installation at a hydro-electric generation project.

Timber Framed Windows Application

Summary

The customer is a manufacturer of timber framed windows and doors for both commercial and private individuals. Currently frames are manufactured on a CNC and handled manually to remove all debris/waste products before the frames move on to the next stage.

Issue to be resolved

Currently during the manufacturing of product, a fair amount of sawdust, woodchips and offcuts are generated which are manually removed and cleaned from the CNC machine to allow for product to move onto the next stage of manufacturing. The customer is looking to automate this to allow for better production throughput, higher efficiencies, and lower costs.

Action taken

The Wire Belt Technical Sales team consulted with the customer to determine what their requirements were for disposing of offcuts, woodchips and sawdust. Through continued discussion with the customer, Eye-Flex® was determined to be the best choice their application, due to the customisation available on aperture/gap size. Along with this, Wire Belt Technical Sales identified that the customer would benefit from using a Straight Conveyor to transport product from the CNC to the next processing station.

Results

Wire Belt has offered the customer a Straight Conveyor fit with Eye-Flex® Conveyor Belting, that will effectively transport the completed product away from the CNC, while allowing sawdust, offcuts and woodchips to fall through the belt, into a collection trough. From here the by-products will be disposed using a vacuum system implemented by the customer.
