System information

Function

The basis for the spreading system CordAliner is two bow rollers. Depending on the angle to which they are pivoted, the two mechanically coupled rollers either stretch or compress the tire cord.

Area of use

Web width control systems are necessary to ensure uniform cord distribution across the entire web width and to ensure consistently uniform material width.

Application

The spreading system can be mounted in all positions. The infeed path should be the equivalent of at least half a web width, while the exit path should be kept as short as possible. Optimal spreading is only ensured if the web is fed centrally into the spreading system.
