DEVICE FOR PRICKING SEMI-MANUFACTURED PRODUCTS OF TIRE

摘要

relates to a tire semi-finished phreaking device of the present invention , phreaking part phreaking gear drive has a different rotation rate by a motor revolution without rotation by internal and external drive gear drive gear driven and phreaking pins pins phreaking body ply semi-finished products are transported by the transfer of phreaking shaft rotation perpendicular to state succession and through the air discharge hole to form , in the pre- process of the formation of air discharge hole King generates a tearing of the semi-finished product which has the effect to prevent any damage to the durability and lowering the reinforcing cord of the semi-finished product . ;
