Automatic Four Head ROPP Cap Sealing Machine | Automatic ROPP Capper

Automatic Four Head ROPP Cap Sealing Machine
The Automatic Four Head ROPP Cap Sealing Machine is designed for automatic sealing of bottles with aluminum ROPP caps using four synchronized sealing heads. The machine automatically handles bottles, positions them under the sealing heads, places compatible ROPP caps and performs controlled cap forming for consistent bottle closure.
The four-head configuration is suitable for higher production requirements where increased sealing output is required compared with single-head ROPP capping systems. The machine can be integrated into automatic pharmaceutical, food, beverage, cosmetic, nutraceutical and other packaging lines using compatible aluminum ROPP closures.
The machine can be configured according to bottle dimensions, neck finish, cap specifications, production capacity and required sealing performance. Automatic bottle handling, cap feeding and multi-head sealing help reduce manual intervention and support continuous production.
What Is an Automatic Four Head ROPP Cap Sealing Machine?
An Automatic Four Head ROPP Cap Sealing Machine is an automatic bottle sealing machine equipped with four ROPP sealing heads for forming aluminum Roll-On Pilfer-Proof caps onto compatible bottles.
During operation, bottles are automatically conveyed and positioned while the ROPP caps are supplied and placed on the bottle necks. The four sealing heads perform the cap-forming operation to create the required threaded closure and tamper-evident ring.
The four-head arrangement allows multiple bottles to be processed during the machine cycle, making it suitable for higher production requirements.
Working Principle
Bottle Infeed
Bottles enter the machine through an automatic conveyor and are transferred toward the ROPP sealing station.
Bottle Separation
The bottle handling system maintains the required spacing and synchronization before the sealing operation.
Cap Feeding
Aluminum ROPP caps are supplied through an automatic cap feeding system and delivered in the required orientation.
Cap Placement
The caps are positioned onto the bottle necks before the sealing heads engage.
Bottle Positioning
The bottles are accurately positioned below the four ROPP sealing heads.
Bottle Stabilization
Bottle holding components maintain the containers in the correct position during cap formation.
Four Head ROPP Sealing
The four sealing heads perform the ROPP cap forming operation using controlled roller movement.
Thread Formation
The rollers form the aluminum cap around the bottle neck thread according to the required closure profile.
Tamper-Evident Formation
The lower portion of the aluminum cap is formed to create the required tamper-evident connection.
Bottle Discharge
After completion of the sealing cycle, the sealed bottles are released onto the discharge conveyor and transferred to the next packaging operation.
