  • Patent number: 6723036
    Abstract: Methods and apparatus for folding pliable sheet material wherein the sheet material is wound on a mandrel to form a roll which subsequently is stripped off the mandrel and transferred to a pleating station at which successive creases are formed in the roll to produce a pleated packet. During the winding of the sheet material the latter is adhered to the mandrel by the application of negative air pressure to the material via the mandrel. Following the formation of the roll, the application of negative air pressure is discontinued and positive air pressure is applied to the interior of the roll so as to facilitate stripping of the roll from the mandrel. At the pleating station the roll is creased successively to form a plurality of pleats and the direction in which the creasing proceeds is such as to facilitate the escape of air from the roll as it is pleated.

  • Patent number: 6635003
    Abstract: A method for laying out an envelope blank on a sheet of material using a template having a straightedge portion with layout edge and an alignment portion with alignment field. The user places an item to be enclosed in an envelope onto the sheet, places marks thereon to locate approximately the corners of the item and removes the item. The user places the template thereon, adjustably aligns the edge of the straightedge portion on the sheet until the alignment element is lined up as parallel as possible with two diagonally opposed marks. The layout edge being thus aligned, the user draws a line representing a layout line substantially along the edge. In repeating this process for each mark, the user draws remaining layout lines. After drawing all layout lines, the user removes the template from the sheet; the envelope blank is formed from the layout lines.

  • Patent number: 6620279
    Abstract: A folding and sealing apparatus comprising a housing supporting a feed platform for feeding a supply of pre-glued forms to the folding and sealing apparatus. The housing accommodating a first roller, a second roller, a third roller and a fourth roller, and the first and second rollers forming a first nip, the second and third roller forming a second nip and the third and fourth roller forming a third nip. A motor drives at least one of the rollers via a drive mechanism. The first roller is a spring biased roller to facilitate feeding of the pre-glued form while the second, third and the fourth rollers are all fixedly mounted to the housing so that the second nip and the third nip both provide a sufficient sealing pressure to the folded form, as the folded form passes through the second and the third nips, to facilitate both folding and sealing of the folded form. A collection bin is provided adjacent the third nip for collecting the folded and sealed forms upon exiting from the folding and sealing apparatus.

  • Patent number: 6612356
    Abstract: A back-up pad is provided over an anvil surface of a back-up plate, and between the anvil surface and a sealing surface of a sealing die, in an apparatus for forming seals between layers of film material. The back-up pad has a slip layer on one side thereof and a firm polymeric support layer on an opposite side thereof, the slip layer opposing the sealing face of the die so that the layers of film material pass between the sealing die and the back-up pad during seal formation. The polymeric support layer may have a Shore-A hardness of at least 10 at 20° C. and a dynamic loss tangent of less than 0.1 from 20° C. to 80° C. An example of a support layer is a polycarbonate pad, and an example of slip layer is a glass cloth coated with Teflon™. The back-up pad is particularly useful for forming lap seals in relatively thick film materials, such as laminated films having multi-layered films laminated together.

  • Patent number: 6592699
    Abstract: A highly stretched film has permanently heat-sealed edges that are nearly invisible. A folding apparatus folds the edge portions of a film to form folded edges. The folded film then is passed through a bridle mechanism having two heated rolls. A series of nips apply pressure to the folded film as it is heated by the heated rolls. The nip pressure, combined with the heat imparted by the heated rolls, causes thermal welding of the folded edges resulting in permanent heat-sealed edges. Because the film edges are folded prior to the hot-stretching, the hot stretch process performs dual functions of stretching the film and heat sealing the folded edges. The resulting stretched film has permanently heat-sealed edges that do no separate, and which prevent tearing of the film edges during subsequent processing and use.

  • Patent number: 6560832
    Abstract: The present invention relates to an airbag cushion which exhibits a low amount of seam usage (in order to attach at least two fabric panels or portions of a panel together) in correlation to an overall high amount of available inflation airspace within the cushion itself. These correlated elements are now combined for the first time in what is defined as an effective seam usage index (being the quotient of the length of overall seams on the cushions and the available inflation airspace volume). The inventive cushion must have at least one substantially straight seam and must possess an effective seam usage factor of less than about 0.11. A cushion exhibiting such a low seam usage factor and also comprising an integrated looped pocket for the disposition of an inflator can is also provided as well as an overall vehicle restraint system comprising the inventive airbag cushion.

  • Patent number: 6544160
    Abstract: A former is used to fold webs longitudinally. During the web drawing-in process, the individually incoming paper webs in a group of paper webs are conveyed smoothly to a folding mechanism at the end of the former. This is accomplished by using a number of upper and lower transport elements which are located above and next to each other at least inside the boundaries of the upper surface of the former. These upper and lower transport elements can be brought together and can be separated. They can be driven as desired.

  • Patent number: 6526733
    Abstract: The invention relates to a device for aligning a packing material tube (1) with a treatment station in a packaging machine in which a tube (1) with a circular cross-section is produced from a strip of printed packaging material having embossed lines. Said tube is closed by longitudinally sealing it, filled and shaped in a cross-sealing unit (12) and divided into cuboid packages. The unit (12) is provided with an adjustable lift of stroke so that it intermittently convey the tube (1). It is also provided on diametrical sides with a folding flap (16) that can be pivoted about an axis (15). For feeling the position mark, a sensor is arranged. The aim of the invention is to facilitate a faster termination of the initial phase when the packaging machine is put into operation while at the same time producing less cuttings and to prevent the paper tube from being damaged. To this end, a folding finger (19) is arranged upstream of every folding flap (16).
