Abstract

The core material, still soft after extrusion, is passed between pressure rollers, while the reinforcing cord is carried to-and-fro by a slide unit mounted on a bowed rail in front of the rollers. The effect is that the cord is applied in lateral zig-zags, pressed into place by the rollers and embedded when the core hardens. The purpose is to provide lateral reinforcing cord in a continuous process.
