  • The filled bottles to be capped are conveyed to the carrier chain of the main unit by the conveyor and then into the machine.
  • Caps are automatically arranged with opening downwards  in the cap feeder and taken to the guide rail in the pre-sealing area along the chute one by one.
  • the chute is provided with a steam ejecting pipe to soften the seal ring in cap. A Cap is left on the neck of each bottle passed the guide rail and pre-sealed under the application of pressing foot and rubber block. Then it comes to the underside of the differential flat belt pressure plate of the sealing assembly and is tightened by the two differential flat belts to twist cap.   
  • Before capping, the bottle passes the steam ejection area first and displaces the air under normal pressure in the top clearance at the bottle mouth with high-speed steam. After capping, the cooling water pipe sprays cold water on its cap to cool down the bottle to vacuum it. 
  • During the entire process from pre-sealing to sealing, the bottle is clamped by a pair of V-belts synchronizing with the carrier chain so that the bottle can go forward smoothly and will not turn.
