Abstract
A belt having stretch reduction features is provided, along with a method for producing a belt having reduced stretch characteristics. The belt is formed of a jacket and a stretch reduction element. The stretch reduction element is formed of a material having a greater modulus of elasticity than the jacket. Additionally, the stretch reduction element is formed by bathing the stretch reduction element to a reactive fluid in an oxidizing atmosphere.
Claims22
A method for producing a stretch-resistant conveyor belt, comprising the steps of:
- providing a thermoplastic jacket material having a modulus of elasticity;
- providing an elongated stretch reduction element having a modulus of elasticity that is greater than the modulus of elasticity of the jacket material;
- exposing the stretch reduction element to a bath of a reactive fluid in an oxidizing atmosphere to alter the surface of the stretch reduction element;
- forming the jacket material into a belt jacket around the stretch reduction element to form a length of belt material having a first end and a second end;
- and
- connecting the first end to the second end to create a continuous belt.

A method for producing a stretch-resistant belt, comprising the steps of:
- providing a jacket material having a modulus of elasticity;
- providing an stretch reduction element having a modulus of elasticity that is greater than the modulus of elasticity of the jacket material;
- exposing the stretch reduction element to fluorine gas in an oxidizing atmosphere to improve the stretch reduction properties of the stretch reduction element when it is subsequently combined with the jacket material;
- forming the jacket material into a belt jacket around the stretch reduction element to form a length of belt material having a first end and a second end;
- connecting the first end to the second end to create a continuous belt;
