Half Skirt Outer Curing Envelope

Features :

• To prevent envelope burst: 2" wicking tapes should be applied at 4 places for proper air bleeding between tyre and envelope. Wicking tape should protrude outside the envelope.
• Pre-inflate the tyres to between 20-30 psi to avoid distortion of the casing caused by the weight of the lid of the tread bonder.
• Maintain the differential pressure of 30 psi between steam pressure and tube air pressure especially at the end of the curing process.
