Combo Belt & Body Ply Machine can switch from running steel belt/breaker material to textile or steel body ply in a matter of minutes. The combo machine shares a common extrusion, cooling and accumulation system, with separate cutting and splicing lines for belt/breaker and body ply. Material is produced in one, end-to-end process, from creel to wind-up, eliminating the need for expensive calendering and off-line processing operations.
The machine is custom-designed for every application and can even be adapted to add extruded textile cap strip manufacture. The basic set-up includes creels for steel or textile reinforcement cords, which feed into a crosshead extrusion die where the cords are fully encapsulated in rubber. The material then passes through a cooling and accumulation unit, before being processed in either the belt/breaker or the body ply machines, and then wound with liner on an in-line wind-up system. In-line hot or cold gum edging of the steel belt can also be added if needed. The machine is operated by a single operator to minimize operational costs.
