Abstract: A folding unit for producing packages of pourable food products from sealed packs having at least one projecting foldable end tab. At least one conveying member cyclically receives a relative pack, by the end corresponding to the tab, and feeds the pack along a forming path crosswise in the axis of the pack. A folding mechanism having an impact surface receives each pack by the end corresponding to the tab, and is carried by the conveying member to move between a first operating position, in which the impact surface forms, with the feed direction of the relative pack, an angle of over 90° and open in the direction of the forming path, to fold the relative tab, upon impact, onto the pack in the traveling direction of the pack, and a second operating position, in which the impact surface is rotated towards and cooperates with the pack.

Abstract: A method and apparatus for folding and bonding a closing seal part of a box-shaped package comprising the steps and corresponding members of folding a strip-shaped closing part of the package on an intermittently running conveyor, preheating outer surfaces of the package beneath said both-side overhanging portions into semi-weldable state, folding said overhanging portions along both outer sides of the package, pressing the folded strip-shaped closing seal portion against upper surface of the package without generating any gap therebetween and heat pressing the folded overhanging portions from outsides; and

Abstract: A tray pack assembly 10 is conveyed through a package forming machine during a final gluing stage by angled continuous belts 37, 38 which drivingly engage side walls of the forming pack 10 and support the pack 10 throughout this operation. To ensure good contact between the pack 10 and the belts 37, 38 and subsequently good contact with compression rollers of a later conveyor bed, two belts 39, 40 of flexible fingers 41 extend above the path of travel so that the tips 42 of the fingers 41 engage the top 14. The provision of these flexible fingers 41 enables deflection of the fingers 41 in the event of the tray having contents which stick above the intended level. The belts 37, 38 enable the spatial relationship between the walls of the pack 10 to be controlled precisely and for squared-off sleeves to be formed thereby.

Abstract: A method for making bags out of plastic material includes the cutting of individual portions from a roll of a tubular element and the simultaneous making of a bottom seam crosswise to the tubular element itself. Each portion is set up as to form a bag with a filling opening at the opposite end of the bottom seam. The extremities of the bottom of the bag are pressed down so as to form angular sections which are sealed by means of seams made crosswise to the bottom seam and folded back against the external surface of the bag. The filling opening is sealed by a crosswise top seam after the bag has been filled with the relevant products. Angular sections are then defined at the extremities opposite to the top of the bag. The angular sections are sealed by means of seams made crosswise to the top seam and folded back against th external surface of the bag.
