    摘要: An apparatus for making a self-opening wide mouth bag pack includes a supply of flexible film material. An extruder forms a continuous tube. A flattener flattens the tube. A first sealer forms a bottom seal across a width of the flattened tube. A cutter cuts the flattened tube into bag blanks has a bag mouth at a predetermined distance from the bottom seal. Second and third sealers form angled seals at lower corners of the bag blank forming a flat bottomed bag. An adhesion knife penetrates the bag pack adhering adjacent bag blanks together in the bag pack. An aperture maker forms apertures for suspending the bag pack from a dispensing rack. The pack is attached to the dispensing rack and the front wall of the subsequent bag is adhered to the rear wall of a first bag, thereby causing the first bag to open when pulled from the rack.

    摘要: The invention relates to a method and an apparatus for deep-drawing a tray (1) from a blank of sheet material (2). The blank is provided with score lines, which determine the location of wrinkles formed in the process. The apparatus comprises a female moulding tool (3), which comprises a cavity (7) for forming the tray bottom outwardly, a male moulding tool (4), which comprises a plunger (11) for forming the tray bottom inwardly, the plunger being movable with respect to the cavity for forming the tray, and clamps (6, 15) with an interface for holding the sheet material and forming a tray rim flange. According to the invention by laterally distancing at least one of the moulding tools (3, 4) from the sheet material leeway is pro-vided for free forming so that wrinkling of the tray side walls is achieved in a controlled manner. Spacer plates (13) may be positioned behind the plunger (11), to adjust its position in relation to the cavity (7) of the female moulding tool (3). The cavity may have a separate bottom plate (8) and spacer plates (9) therebelow, or screw means may be provided for adjusting the distance of the bottom of the cavity from the clamp interface and thereby varying the depth of the tray.

    摘要: A method is disclosed for forming a windowed packaging material. According to the method a web of packaging material is cut in substantially the machine direction along a non-linear path. The cutting action provides two subwebs, each having protruding edge portions and recessed edge portions. The two subwebs are displaced relative to one another so that the protruding edge portions face one another. In this configuration opposing recessed edge portions form windows. The two subwebs are adhered to one another at the opposing protruding edge portions. The resulting windows may be covered with a material that is transparent and/or breathable. A strip of handle material may be applied spanning the respective windows.
