    Abstract: An improved top opening, rectangular flexible bag for containing a stack of highly compressed flexible articles. The bag has front and back panels, two side panels and top and bottom panels, all of which are connected together to form an internal compartment for containing the stack under high compression. The stack is arranged within the bag in such a way that the side panels are under tension. The line of weakness defines the entire top portion of the bag which can be easily removed, thus exposing the entire contents of the bag for easy removal. The improvement to the bag is that the line of weakness is applied to the front and back panel of the bag simultaneously, thus providing perfect alignment of the lines of weakness where they intersect the side seals of the bag. The bag is further improved with a notch where the line of weakness intersects the side seal, thus significantly reducing the force to initiate the tear through the bead of plastic created by the side seal.

  • Patent number: 5049117
    Abstract: An envelope machine which makes two envelopes at once. One web is used up to a relatively advanced point in the envelope forming process to simultaneously form two envelopes. At a terminal portion of the envelope processing, the web is cut lengthwise to form two envelopes. The device also includes improved structure for maintaining uniform the tension on the web. This need for uniform tension is made more prevalent by the thickness of the web which must be used to form two envelopes in parallel. The structure of the present invention which maintains uniform the thickness of the web is formed herein by a dancer roll which moves in a longitudinal fashion in cooperation with movement of other associated rolls. Whenever the dancer roll reaches one of its stopping points, it sets off a limit switch which operates a piston to change the type of moving being applied to the dancer roles.

  • Patent number: 4992128
    Abstract: Holders for flat objects such as computer disks which can provide pages of a book which carries such objects, instruction for their use and etc. Each page is made of a single sheet of foldable material, preferably spunbonded olefin (such material being available from DuPont under their tradename "Tyvek"). The sheets are cut into the shape of rectangular center panels with bottom and side flaps extended therefrom; the side flaps extending from opposite side edges of the center panel and being off-set from each other. Since a single sheet is used it may be printed with visible indicia (e.g., the name of the manufacturer of and the computer program on the disks), prior to cutting, by conventional printing techniques in one pass through the press. The cut sheets (blanks) can then be manipulated in envelope manufacturing equipment which scores, applies adhesive lines and folds the flaps to provide a plurality of partially overlapping pockets, disposed one above the other.

  • Patent number: 4988332
    Abstract: A method for the production of packing bags which can be stacked on a wicket and unfolded while being filled, and for that purpose are provided at the bottom end of the bag with exposed wicket perforations disposed in a wicket tab. The bag is made from an outspread web which first is assembled to an open-sided tube and then into a flat-folded tube and bonded. The outspread web is severed in the area of the bag-length boundaries which set the bag lengths apart from one another, by means of a cut made transversely of the web, which produces a castellated outline. The bottom area and top area of two bag lengths lie adjacent one another and yield interfitting tabs and notches. The tabs in the top area can be laid one on the other to form a handle section and at least one tab in the bottom area is used as a wicket tab. Unneeded web material between the tabs is cut away.

  • Patent number: 4913693
    Abstract: A false gusset (12, 82) is positioned between bag panels (26, 28 and 98, 100) to form a bag having a handle (24, 80) at its upper end formed by upward continuations of the sides (26, 28 or 98, 100) of the bag (10, 78). This construction removes the false gusset (12, 82) and the seals (66, 68 or 114, 116) which connects the false gusset (12, 82) to the bag panels (26, 28 or 98, 100) from the forces created by the weight of the bag (10, 78).

  • Patent number: 4909779
    Abstract: A web of flat plastic bag stock formed with transverse perforations and heat seals is separated into individual bags, then individually formed in plural folds and the folded bags are stacked for packaging. To form as many as three folds, four rollers are used. The individual, separated bag is forced between the first and second rolls by a reciprocating first "blade" which contacts the middle of the bag. After being formed with the first fold, the bag is forced between the second and third rolls by a reciprocating second "blade". The twice-folded bag is then forced between the third and fourth rolls by a third reciprocating "blade" and, after the third fold, is conveyed away on belts to a stacking station where plural bags are deposited as a layer on a table. The layers may be packaged by hand or by suitable machinery.

  • Patent number: 4899520
    Abstract: A packaging machine and method for simultaneously loading, sealing and severing bags forming part of at least two independent chains of bags. Two juxtaposed nip roll assemblies including axially aligned feed roll portions can be independently actuated in order to selectively feed one or two webs. A drive motor, having a dual output, is selectively coupled to the nip roll assemblies by clutch/brake units which can be selectively actuated. After a bag or bags are loaded, a sealing mechanism is actuated to seal the loaded bag or bags. A sensor monitors movement in a seal unit member and terminates the sealing cycle if movement in the seal member occurs prior to the pressure bar reaching a predetermined position. While a bag or bags are being sealed, a tear off mechanism including a rod-like member is advanced into and through the web path in order to sever the loaded bag from the remainder of the web.

  • Patent number: 4650453
    Abstract: A flexible web which is caused to run through a cross cutter to be severed at regular intervals in order to yield a series of discrete sections is engaged by a pair of holders which attract the web by suction immediately behind the severing plane when the cutter severs the web. The holders advance with the web and thereafter with the freshly formed section to prevent changes in orientation of the sections on their way to a removing station where they are expelled from the path of the web by block-shaped commodities which are draped into the respective sections. The surfaces of the holders are small and the length of each holder is a minute fraction of the length of a section, as considered in the longitudinal direction of the web. The holders are mounted on endless toothed belt or chain conveyors which advance the holders along an endless path having an elongated reach extending adjacent to the path of movement of the web and its sections toward, past and beyond the severing station.
