VSS Paper Bottom Sealer
Design and Function
fully automatic, indexed closing machine in rotary turret design
Feeding of the can bodies
- feeding the filled cans or unfilled can bodies to the machine on a horizontal conveyor belt (optional)
- separating the cans by central star wheel
Feeding of the paper bottoms
- inserting the prefabricated paper bottoms into the bottom magazine
- gentle extraction of the cardboard bottom from the magazine by means of vacuum
Heat-sealing process
- exact positioning of the paper bottoms in a form ring
- calibrating the can bodies by means of the form ring
- precise orientation to the paper bottoms
- correction of slight deformations of the can body
- controlled lifting of the bottom and can body into the sealing tool
- heat-sealing of paper bottom with can body
- by inner and outer heated sealing tools
- utilizing robust and easy-to-use heat contact technology
- with adjustable and monitored temperature
- long sealing times (up to 1.65 s) thanks to turret principle
Format Change
quick change to other can formats using
- manual height adjustment without change parts
- very good and easy access to the tooling area
- short changeover time for preset sealing head with quick change mechanism
