Two-in-one machine

The DUO AT53 model is the result of the experience acquired in the production of hundreds of combined hooding machines, using a patented system for the preparation, opening and positioning of hoods taken from tubular film with side bellow sections.
Using an arc hot air generator it is possible to obtain hooded and perfectly heatshrunk packs resistant to atmospheric agents, with maximum operational efficiency in a single and truly compact operational unit of limited space.

The hood preparation takes place at the side of the hot air generator, this means that the tubular film is in no way affected by the heat, furthermore the fact that the bag formation, hooding and heat shrinking phases occur simultaneously translates into faster cycle times and increased productivity; The lower edge of the hood is fitted under the bottom of the product stretched by four pegs to make the best possible use of the actual material, and also making material saving possible making it possible to use a tubular reel of reduced perimeter. Four jets of compressed air inflate the bag during arc descent thereby facilitating the positioning and eventual sliding of the film over the upper edges of the pack; The film is secured to the base of the product thanks to a suction device therefore avoiding a ballooning effect as the result of the expansion of the air actually inside the bag during heating and heat shrinking.
