PVC reinforced hose machine

We produces extrusion plants for reinforced braided flexible PVC hoses, with 12+12 or 18+18 threads of polyester.
The product is formed by a first flexible PVC layer strengthened with threads wrapped of polyester, and then covered by a second flexible PVC layer.

The line use a first extruder which produces the internal layer, subsequently cooled and fitted with threads.
Then the hose passes in a coating cross head to team  which  covers with a second layer of flexible PVC.
In order to increase the adhesion between the two layers a vacuum system is directly applied in the coating die head.
