A conveyor belt is basically one or more plies of fabric carrying a load while being pulled along a support mechanism. The strength of the belt, it's ability to trough, load support, and tracking are all dependent on the fabric. Rubber is used to bond or laminate multiple plies of fabric for increased performance. The fabric plies and the skims of rubber that bond the plies form the carcass. Rubber covers may be used to protect the carcass. Legg Company offers a variety of carcass selections to chose from. Customers may choose from fabrics of Polyester, Nylon, Cotton, or a blend such as Polyester/Nylon or Cotton/Nylon. Legg Company believes in giving the end user and distributor the ability to custom engineer products to suit exacting applications. Legg Company has standard belt carcasses already formulated with exacting carcass constructions for the more common applications.  For applications requiring a different belt, contact us, we'd love to provide your ultimate belt.

 

 

 

 

 

 

 

 

 

 

 

 

TIGER®
POLYESTER WARP -- POLYESTER FILL -- PLAIN WEAVE

The polyester warp yarns of the TIGER yield great strength with a minimum of stretch.  The TIGER is ideal when take-up is in short supply or when excessive stretch causes the belt to be cut and hot spliced again, costing time and money. Superior tracking is another great benefit of the polyester warp yarns of the TIGER.  The polyester fill yarns gives the belt good lateral stiffness and increased load support. The TIGER carcass has excellent chemical resistance and has good heat resistance.  The all polyester carcass resists moisture absorption, allowing the TIGER to run even in submerged applications without the carcass distorting.  Polyester retains more of its dry tensile strength when wet than other fabrics.  The TIGER carcass is manufactured using high grade compounds with high elongation and high adhesion properties.  Since polyester is more stable than nylon when subjected to extreme temperature fluctuations or moisture, it is superior for fabrication involving hot vulcanization.  The TIGER is available in a 75 lb*., and 110 lb*., rated fabrics.  The TIGER is one versatile carcass at home in varied conditions.

 * Maximum Allowable Working Tension is based on a safety factor of 10:1 vs. actual break tensile in a cured 3 ply belt sample.

GRIZZLY®
POLYESTER WARP -- NYLON FILL -- PLAIN WEAVE

NOW WITH S&Z TWIST

Our number one carcass!  The GRIZZLY  incorporates a powerful carcass of polyester warp yarns and nylon fill yarns.  The GRIZZLY has been engineered for maximum performance in a wide range of applications.  The polyester warp yarns give the GRIZZLY great strength while keeping stretch to a minimum.  Stretch can be critical in applications such as machinery where take-up is short.  Minimal stretch can save money if other belts stretch past the allowable take-up and a section of the belt must be removed and the belt spliced again.  The GRIZZLY carcass is easy to track and train due to the polyester warp yarns. Polyester maintains more of its dry tensile strength when wet than other yarns so the GRIZZLY is well suited for unprotected applications.  Polyester has excellent chemical resistance and will not weaken or stretch under chemical deterioration.

 The nylon fill yarns of the GRIZZLY enhance performance.  The GRIZZLY is resistant to ripping and tearing due to the nylon fill yarns.  The nylon fill yarns will also provide excellent retention for mechanical fasteners. Nylon fill yarns are supple, allowing for a more flexible belt.  This flexibility will allow the belt to trough under lighter loads.  The additional strength of the nylon fill will increase the impact resistance of the belt.  The GRIZZLY carcass incorporates the Legg standard high elongation and high adhesion compounds for the skims.  It is available in a 125* lb. and 225* lb. rated fabric.  The GRIZZLY is one strong, agile carcass.

 * Maximum Allowable Working Tension is based on a safety factor of 10:1 vs. actual break tensile in a cured 3 ply belt sample.
