Zero Degree Breaker Line
Application: specially used for preparation of zero degree breaker of all steel radial truck tire.
It mainly consists of creel stand, pin cold feed extruder, extruder head, temperature control system, pull-off device, storage device, double-station winder, automatic control system, etc. Its characteristics are as follow:
l There are two kinds of creel, i.e. air controlled constant tension type and weight dropper type, and the costumer can optionally select either.
l Unique head structure and flow channel ensure reasonable extrusion pressure, high precision sizes of goods and good surface quality.
l Advanced automatic control system and high quality configuration can largely increase inherent quality of goods and high reliability of the system.
l Originative double-station winder makes the operation simple and convenient.
