RHO III - Direktsiegelmaschine

RHO III - Metal Can Sealer

Overview

  • modular machine for heat-sealing of peelable composite membranes onto
    - welded metal or deep-drawn metal cans without additional ring end 
    - cardboard and plastic cans (optional)
    - circular and non-circular formats
  • up to eight working stations on a turret
  • up to 300 cans per minute
  • enormous poential for cost savings compared to the use of conventional peel-off-ends while maintaining comparable barrier and convenience properties
  • eliminating the tinplate from the ring
  • tight seal even in the area of the welding seam

Technology

Infeed of can bodies

  • can body separation by driven stop star and acceleration by infeed screw
  • inductive pre-heating and transfer to the heat-sealing station

Membrane feed

  • effective material utilization using optimised coil layout
  • double-sided decoiler for stop-free coil change
  • servo-driven take-off rolls for smooth decoiling
  • automatic scrap web discharge
  • patented servo transfer system using vacuum handling

Direct-sealing

  • heat-sealing of cans under adjustable pressure
  • creation of hermetically tight seal
  • long times of operation and trouble-free production
  • aligning of upper and lower sealing tool using high-precision linear guidings and cam-driven advance
  • isolation of the tooling and the guidance with high quality polymeric material for high thermal load
  • long sealing times of more than 0.6s
  • equalization of discntinuities in the area of the welding seam using an elastic sealing stamp
