SLEEVE WRAPPING MACHINE

MS70

Automatic and semi-automatic welding bar machines with in-feed motorized belt conveyor.

• MS70 L/AL models represent the maximum simplification in bundling machines
• They are made with a single supporting structure
• MS70 L/AL models shrink single or grouped items with polyethylene film
• Max package width depends on package height
• Welding bar with film cutting blade (no smoke during welding phase) operated by pneumatic cylinder
• PE shrink film 35 to 100 μm
• Work surface height: 850 +/-25mm
• Air consumption: 8 NL/min + 6 bar air supply needed
• Power supply: option between 3phase 220V & 3phase 400V + Neutral
• Safety photoelectric cell that blocks the sealing bar if it finds an obstacle on its trajectory
• Automatic upper & lower reel film unwinding system with pinch rolls
• Max shrink film reels diameter: 350 mm, thickness: from 35 to 100 micron
• Shrink tunnel isolated with rock wool and heated by resistances
• Forced ventilation with air recycling
• Temperature control of the sealing bar and the tunnel with PID temperature controllers
• Tunnel conveyor belt controlled by adjustable speed gear motor in steel fine net with side chains
• Switch for changing between automatic cycle and manual/semi-automatic cycle with pedal start

• Product containment guides after the welding bar
• Pack cooling unit installed at tunnel exit
• Self-dimensioning to product with mechanical pressing unit for unstable products
• Film presser roller unit
• Product protection lateral guides positioned inside the tunnel
• Machine mounted on casters
• Conveyor section with thick rollers positioned under the package cooling unit at the exit. Ideal for good bundling of products that are group packaged only by film
• Film spool insertion rollers (upper and lower) to facilitate the operator for the spool change
• Signal system indicating the end of the film reel
• Automatic upper and lower film spool centring system by means of a hand wheel
