HF’s ONE Tire Building Machine is the answer to new challenges in tire manufacturing and market demands.

High flexibility

• ONE machine, three possible carcass drums
• Quick change-over of different carcass drums without changing the shaft < 20 min.
• High force, long hub, servo driven for symmetrical turn-up movements => SW width up to 230 mm (+)
• Low final shaping distance => 180 mm bead to bead

Tire quality

• Less stress on ply due to flat turn-up
• Separate IL and SW application
• No ply ending in SW area due to C turn-up
• Constant cord length bead to bead
• Very accurate SW inboard edge application
• Ply-down to reinforce the carcass
• Automation of former two-stage process with permanent bead control

Tire cost

• High C turn-up => Reduces material and tire weight
• No sidewall cracks when tire is in use due to elimination of ply ending in sidewall area
• High efficiency
