FLEXOBORD ®

FLEXOBORD ®
Product Presentation

Flexobord belts are based on the following main components:


1) Base belt
2) Sidewalls
3) Cleats


The correct choice of each component in relation to the final use is one of the most important contribution to the overall plant performances. The complete range of SIG belts is produced according to the international standards; therefore the cross reinforcement of the carcass ensures the necessary transversal stiffness and prevents from hitting the full width return idlers.

Sketches on the right show typical but not exhaustive Flexobord layouts; the belt designer must take into consideration these alternatives to guarantee correct plant performances.

Base Belt - The Cross Stabilized Construction

The main required characteristic of a base belt suitable for Flexobord applications is the controlled transversal stiffness, also named cross stabilized construction.

 

The following sketches indicate the consequences due to a wrong choice of the base belt:

 

 

Standard base belt without any particular transversal stiffness are usable only for horizontal flat belts made with only corrugated sidewalls without transversal cleats.

 

According to the heaviness of the application, the following base belt typologies are available:

 

XR Composed by only textile fabrics with high transversal stiffness; two special synthetic layers assure the correct cross stabilizing properties. They are provided with cut edges for light and medium applications.
This base construction can be sold as indipendent product with the brand name TEXRIGID®. The sketch on the right shows the cross stabilized construction.

They are provided only with moulded edges.
This cross stabilized base belt can be sold as indipendent product with the brand name CROSSRIGID®.

Standard production length: 200 m;
The transversal stiffness of CROSSRIGID is not suitable for sealing applications unless supported over the whole belt width with a suitable rigid structure; specific constructions are necessary for these special products to assure the static stability when rest only along the edges: SIG SpA designs and produces such a products with the brand name SEALTEX.

 

 

ST Designed for the heaviest applications where high elevation and/or conveying capacity are involved, it is composed by longitudinal steel cords with a special transversal steel reinforcement to assure the required stiffness. Full range is available from 1250 to 3500 KN/m; for the correct belt selection, please contact our technical dept.

 

COVER SELECTION
Base belt can be provided with alternative rubber covers with reference to the specific application. On request, special productions with cleats and edges of the same rubber of base belt can be realized; please ask our sales dept to verify all details.
