Abstract
A flat belt provides an endless traction suitable for conveyor belts, and has no fabric insert in the force transmission region. In some embodiment it has no fabric insert in the back of the belt. The flat belt is formed by a multistage method which includes forming a flat belt with a main body and endless tension member elements, by a rotary vulcanization process, and subsequently forming at least a part of the force transmission region on the flat belt. The flat belt may be used in agricultural machines which convey agricultural harvested material.
Claims9
Flat endless belt, comprising:
- a length of at least 3 m,
- a main body comprising an endless tension member element formed from a multiplicity of tension members configured for transmitting tensile force in a running direction of the flat endless belt,
- wherein the flat endless belt has no fabric insert in a force transmission region wherein at least a part of the force transmission region, following vulcanization, is formed from the main body by a material-removing method.
Method for producing a flat endless belt having a belt length of at least 3 meters, comprising
- a) forming a flat belt with a main body and an endless tension member element, present therein, by a rotary vulcanization process;
- and
- b) forming at least a part of a force transmission region on the flat belt obtained by the rotary vulcanization process according to step a), wherein the force transmission region is produced by at least partially forming a first traction profile and wherein in step b) material of a vulcanizate is removed.
