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
