Abstract

1297849 Wrapping machines WALDYSSA SA 15 May 1970 [20 May 1969 20 March 1970] 23768/70 Heading B8C A wrapping machine comprises a lifting table 22 which pushes an article (e.g. a filled tray) P against a sheet of stretchable plastics foil and through an opening 3 in a folding plate 2 so that the foil is stretched over the top and sides of the tray P, a folding mechanism 26, 29 which folds the edges of the foil sheet against the bottom of the tray P, and a conveyer 33 which pushes the wrapped tray of the folding plate 22. A continuous fold web is pulled off a roll A by a pair of drive rollers 4, 5 and held to a position between converging upper and lower endless belts 11, 111 driven at a higher speed than the drive rollers 4, 5. The drive rollers 4, 5 are then stopped and a perforating tool 17, e.g. an incandescent wire in zig-zag form, is raised to perforate the web B, the drive rollers 4, 5 then being restarted to advance the web B until its leading edge is gripped by the belts 11, 111 so that the foil sheet is torn from the web B along the perforation therein. The belts 11, 111 carry the foil sheet to below the opening 3 in the folding plate 2 where two thrust bars 20 are raised to clamp the side edges of the sheet against the folding plate 2. A filled tray P is fed on to the lowered lifting table 22 by a pair of conveyer chains 24, and activates a switch 78 which controls the entire operation of the machine. The lifting table 22 is then raised until the tray P is situated above the folding plate 2. A pair of pivoted angular folding levers ?6 (Fig. 5) are then swung inwardly to fold the side edges of the foil sheet under the tray P, the thrust bars 20 not being released until partial folding has taken place. A bar 29 carried by holding rods 30 is then advanced across the folding plate 2 to fold the rear edge of the foil sheet under the tray P. The conveyer 33 comprises an endless belt of resilient material which exerts downward pressure on the tray P during folding, and which is actuated to push the tray on to a discharge conveyer 25. During movement of the tray P off the folding plate 2 the leading edge of the foil sheet is folded by one edge 103 of the opening 3. If the foil material has not sufficient adhesivity to hold the folded conditions, a heat sealer 38 is situated below the discharge conveyer 25. In the embodiment of Fig. 17 an endless belt 85 of "Teflon" (Registered Trade Mark) runs around the rod 29 and a roller 84, thereby avoiding friction between the rod 29 and the foil sheet. In another construction, the lifting table 22 has pivotally mounted tray supporting fingers (80, Fig. 15, not shown) which are pivoted against the action of spring (82) by the folding levers 26 during closure thereof. In still another embodiment there is provided four thrust bars (120, 220, 320, 420, Figs. 16-32, not shown) adjacent each edge of the opening, these bars being actuated to release the respective foil edge after the respective folding has begun.
