The present invention is a grooved belt, or surface roll where applicable, and a method for making these belts or rolls, comprising placing a chemically reactive material on a partially completed belt surface, and depositing an elastomeric material onto the chemically reactive material which reacts and forms a bond therewith to create a pattern. Placement of the elastomeric material is used to create the grooves, for example. The grooves are formed without machining and the resulting belt surface is smooth and uniform without cuts or cracks.
La présente invention concerne une courrroie rainurée, ou un rouleau rainuré le cas échéant, et un procédé de fabrication de ladite courrroie ou dudit rouleau. Le procédé consiste à placer un matériau chimiquement actif sur une surface de la courroie partiellement terminée, puis à déposer sur le matériau chimiquement actif un matériau élastomérique qui réagit et se lie à celui-ci pour créer une structure. La mise en place du matériau élastomérique sert à créer des rainures, par exemple. Les rainures sont formées sans usinage et la surface de courroie résultante est lisse et uniforme, sans coupures ni fissures.
