Traditional fiber-wall-element model is typically all to make fiber radial oriented (i.e. the direction of fiber is vertical with tyre surface) emphatically, and it takes
Complicated, the operating difficulties to principle, and degree of orientation is not high, finally makes to recap anti-wear performance improvement seldom.Fiber is through squeezing
Go out in machine the flow regime (axially, circumference and radial direction) for there are 3 directions, axial orientation has no chopped fiber to its performance in the tread
The improper consistency problem that can also exist with rubber of beneficial effect, such as fruit fiber pre-treatment, so as to occur de- with rubber under high temperature
The phenomenon of layer, the quality of final influence rubber tyre even causes security incident.
Utility model content
The utility model provides the enhancing of stacked fiber planar orientation and remanufactures extruded tread shaped device, including connection
Entrance, runner plate, changeover portion, orientation section, sizing section and mouth template together；Entrance set flange and along extrusion direction
