Two-stage building machine for OTR tire

Two-stage building machine for OTR tire

Application:Be used for the molding of 40.00R57 or other sizes(as 36.00R51、33.00R51 etc)type OTR.

Structure features

First-stage building machine adopt the harmomegathus metal drum (independent innovation technology and have patent certificate), run stably, with high repeatability precision, accurate locating,, dispense with removing the shoulder of drum, reduce the labour intensity and improve efficiency 20%.
Second-stage building machine adopt the radial direction harmomegathus ring form cylinder drum, which can be reliable to avoid the cord thread back, the end-product quality be enhanced 90%. The pneumatic and electronic control system are advanced and reliable.
