Sealing Machines: RHO I

Sealing of membranes to lid-rings

Technology:

• Pressure and heat are used to seal a membrane to a metal lid-ring.
  
• This makes for a hermetically tight and extremely reliable seal to allow sterilizeable closures.
  
• Modular system with turret principle
  
• The flexible modular system can be adapted to different technological operations and output requirements
  
• The machine is available in versions with 1 or 2 lanes for membrane coil.
  
• Optimized material utilisation of the membrane coil according to the lid-ring size.(less scrap)
  
• Two membranes are cut out in a single stroke from the membrane coil.
  
• Both high output and high quality.
  
• In the first module the membranes are cut out and transferred to the turret for pre-sealing.
  
• An hermetically tight and extremely reliable seal is created by long sealing times.
  
• In the second module final sealing takes place with more than 0.5 seconds pure sealing time. More than 230° of the turret rotation is available for sealing.
  
• In the third module the membranes are embossed.
  
• Prior to embossing, the stay-on tab is folded down facing inwards and embossed at the same time.
  
• The sealing pressure and sealing temperature can be set individually for each station.
  
• Each sealing tool is fitted with two automatically controlled heating systems
  - one at the top and one at the bottom.
  
• If a sealing tool is too hot or not hot enough, this station is deactivated during production and left empty. (No membrane is cut out and no lid-ring is placed to this station)
  
• The transport of the membrane coil and scap skeleton is carried out by servo drives.
  
• The machine is suitable for processing different sealable materials, e.g. laminated aluminium-foil, plastic.
  
• In each working station in all modules, compound tool-sets are used for a quick change of the dies:
  • for membrane cutting,
    
  • for pre-sealing,
    
  • for final sealing,
    
  • for embossing.
    
• An entire format change can be carried out in less than two hours.
  
• Very little maintenance is required thanks to the high-quality components used.
  

Options:

• Flexer for the membrane coil
  
• Fragmentation of the scrap skeleton
