Fully automatic sleeve-wrapper with lateral feeding for “multipackage" (several products wrapped up together on several lines) without an operator. Practical high-speed sleeve-wrapping machine able to package a wide range of products (bottles, vases, jars, pots, cans, phials, cases etc) and to shelter boxes integrating and/or replacing the use of carton boxes at end-of-line with great management advantages. The machine is compact and consists in a sealer and a tunnel; it works in a very simple way: a motorized in-feed belt conveyor, situated at 90 ° from the sealing bar, drives the products from the loading area towards the sealing area. Then a transversal sealing-bar (that has a pneumatic movement and temperature is electronically controlled) cuts and seals the film. At this point the wrapped product enters the tunnel for shrinking. Ideal for high outputs.

• LATERAL automatic feeding
• Sealing time electronically adjustable
• Sealing-bar with two sealing blades and one teflon-coated cutting blade controlled by electronic thermo-regulator ; pneumatic movement
• Product detected by a system of photo-eyes
• the wrapped product stays on a plate behind the sealing area till the outcoming wrapped product pushes it onto the tunnel belt conveyor that is always running
• In-line in-feed belt conveyor running with fixed speed
• Tunnel steel zinc-coated mesh belt conveyor
• Tunnel air heating by finned resistances controlled by an electronic thermo-regulator
• Closed and forced air circulation with air flow adjustable by flaps in order to have the best shrinking 
• Cooling fan at the tunnel exit included
• Internal tunnel parts made by steel zinc-coated
• External powder painting
• Double-rolls system with motorized top and bottom film-unwinding

Options:

• Customized in-feed belt conveyor
• Vertical rollers to compress the film excess at the tunnel exit
• Customized tunnel and sealing-bar height
• After-sealing-bar top-clamp to block unstable products
• Frequency AC engine controller for tunnel belt conveyor
• Discharging idle roller conveyor

The machines works with single-wounded (flat) LLDPE
