FLEXOBORD ®
Presentazione Prodotto

I nastri trasportatori in gomma FLEXOBORD sono costruiti con i seguenti componenti:

 

  1. Nastro base
  2. Bordi
  3. Listelli

Questi tipi di nastri in gomma sono comunemente conosciuti come Nastri Trasportatori con Bordi e Tazze. 

 

La scelta corretta di ognuno dei componenti in relazione all’applicazione finale del nastro è da considerarsi come la più importante valutazione ai fini delle performance dell’intero impianto.
L’intera gamma di produzione di SIG è realizzata secondo gli standard internazionali; il rinforzo trasversale della carcassa assicura quindi la necessaria rigidità trasversale evitando così interferenze del nastro con i tamburi di ritorno.
I nastri Flexobord possono avere diverse configurazioni / costruzioni per garantire prestazioni adeguate secondo i requisiti richiesti dal sistema di trasporto in termini di velocità, inclinazione, ecc

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:

 

Nastri Trasportatori in Gomma Flexobord

 

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.

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.
