Abstract (en)
An automatic wrapping machine for packaging products, materials and palletized units, to be wrapped with a thermoretractible tubular film, comprises a casing (1), at the centre of which the material to be packaged is positioned in order to receive a wrapping of thermoretractible tubular film formed as a bag with bottom at the top, and is equipped with heating means to carry out the thermoretraction of said film after the material has been wrapped therewith. According to the invention, said machine is provided with a plurality of movable gripper members (6), by means of which said film wrapping is picked up in the form of a bag at the side of said casing, is lifted, is opened and is transferred into said casing above the material to be packaged, as a prismatic bag, being then lowered so as to wrap said material. Said gripper members consist of pairs of grippers which grip the folded tubular film on four edges. The machine also provides for the reel (B) feeding the thermoretractible tubular film to be rotatably supported between two end cones (10) suspended by means of flexible elements (9) to the machine casing. Furthermore, said heating means to carry out the thermoretraction of the film consist of a ring furnace (8).
