PVC PU NITTRA Conveyor Belts

The conveyor belts with a PVC covering are used in all types of industry  and have rightfully become the most important part  in the  belt conveyor market . 

The wide range and selection of NITTRA ® products allows to satisfy almost every need both for the industrial use and the food contact one. 

In addition to PVC belts our range includes conveyor belts PU whose technical features allow a longer working life, a lower roll diameter as well as a higher resistance to temperature. 

In order to ensure an efficient technical support in any working condition, our range includes also belts with particular coverings such as felt, rubber, Teflon, elastomer polyester and silicone. 

Thanks to the efficiency of our production facilities, we are in a position to apply guides, profiles or flexible side walls to almost every type of belts. 

All this together with the expertise of our technical staff always allows our customers to find the most suitable solution and, at the same time, the cheapest one.

 

JOINTS  SYSTEMS
The characteristics of  the   new materials and the steady technological progress in the applications of conveyor belts, has led us to the development of various  and specific joint systems.
The most common types are the following ones:

GROOVE JOINTS : they are characterized by high flexibility and   guarantee the best performance at high speeds or against bending.
OVERLAPPED JOINTS: They are  used for particular applications,  as ,for example, when a product  tends to  interpose between the drums and the belt, thus creating a stress in the junction area.
METAL JOINTS: they offer a very short    belt replacement time because  it can be mounted  without any intervention on the structure of the assembly. They are available in different types and in galvanized steel  or stainless steel .
SUBMERGED JOINTS: they  are metallic joints where ,in the junction , the  belt covering material has been reconstructed.
They add  both the flatness and the  continuity of the conveying surface to the features of metal joints.

 

CURVED BELTS
One of the most significant applications of flexible fabrics is the one concerning the manufacture of curved conveyor belts.
In the curve, it is not possible to use rigid fabrics, since, to manufacture them, the cut is made along an arc of circumference and not in a straight line (parallel to the warp) as it happens for all the other types of belt. If for example the curve that must be achieved is 90 degrees, the material will have to be cut for a double angle (180 degrees), plus a further increase, necessary to obtain the overlapping  of the joint and compensate the bending  radii of the drums.
This last increase will vary depending on whether the drums are cylindrical or cone-shaped.
The conveyor belt made of two cone-shaped rollers  is the most precise technical solution from the point of view of the pulling easiness and assembly.
In case cylindrical rollers of few tens millimeters of diameter, one of which will be the tensioner, the cutting is often successfully made by simply doubling the angle and adding only the extra piece necessary for the overlapping during sealing.



BELTS FOR  CUTTING MACHINERY
3 R 12 LD belt  is an exclusive offer of A ZETA GOMMA.
It is especially designed to be used in cutting tiles machinery.
This 3 plied-fabric belt with thermoplastic rubber coating has numerous advantages if compared to traditional PVC belts with red and black rubber covering:

 

  • NO Grinding needed. The tape is manufactured at the origin with a constant thickness
  • NO BONDING: the belt covering forms a single body with the base, therefore no bonding is made thus obviating the possible problem of double tension between belt and rubber)
  • MAXIMUM WIDTH 2000 mm!!
  • HOT VULCANIZED JUNCTION :no visible sign of the junction on the belt surface
  • FAST DELIVERY: If urgently needed the belt can be manufactured in 4 hours.
  • INFERIOR WEAR of the discs: Empirical evidence has shown that this belt, if properly used, reduces the discs wear.
