Fabric dividers

Fabric dividers

The fabric layer can consist of up to six spacers connected by rubber interlayers. Fabric spacers can be made of various materials:


Material used




Structured fabric


Poliamide (nylon)






At present, plies are mainly made of fully synthetic materials, because experience has shown that these materials have the properties to achieve the best performance of belts.

The fabric spacer consists of a carcass of polyester fibers (E) arranged longitudinally and a polyamide weft arranged transversely (P), creating a material called EP. Spacers made of EP perfectly absorb high tensile forces, undergoing only slight stretching. In addition, they are resistant to many chemicals and impacts and are characterized by good adhesion and insensitivity to moisture and water.

The longitudinal tensile strength of the tape depends mainly on the fabric layer used. The value of the tensile strength of the entire warp fabric is always given in N/mm of the belt width. The normalized values ​​of the tensile strength of individual spacers are as follows:

63 – 80 – 100 – 125 – 160 – 200 – 250 – 315 – 400 – 500 – 630 (N/mm)

The tensile strength of the entire fabric warp is the sum of the values ​​for the individual plies, rounded to the nearest normalized value. The normalized values ​​for the whole warp (according to DIN 22.102-1/04-91) are as follows:

200-250-315-400-500-630-800-1000-1250-1600-2000-2500-3150 (N/mm)


  • EP 200/2:   tape with 2 plies, strength for each layer – 100 N/mm, total tensile strength – 200 N/mm;
  • EP 400/3:   tape with 3 plies, strength for each layer – 125 N/mm, total tensile strength – 400 N/mm;
  • EP 630/4:   tape with 4 plies, strength for each layer – 160 N/mm, total tensile strength – 630 N/mm;
  • EP 1000/5:   tape with 5 plies, strength for each layer – 200 N/mm, total tensile strength – 1000 N/mm.
