Abstract (en)
The wrapping station comprises a pair of vertical walls (14) in mutual opposition on respective sides of a conveyor (13), which carry respective sets of sprockets (15) positioned at different heights in relation to the conveying surface and driving a pair of looped chains (16) interconnected by cross rails (11) cycling through at least four positions: a first, in which the film (2) is restrained by a pack (6) of commodities to be wrapped and taken up by the rail (11), a second in which the film (2) is elevated by the rail above the pack (6), hanging in two folds of combined length equal to the required wrapping length, and a third in which the rail (11) descends a short way, allowing the film to be cut to the required length, the cut sheet (S) is then drawn forward by the rail over the commodities and released onto the leading face (F) of the pack in a fourth position. The sprockets (15) are mounted to height adjustable supports (24), and can thus be repositioned to suit the packaging format. <IMAGE>
