  • Patent number: 10183796
    Abstract: A bag has front and back face panels having upright longitudinally extending side edges and transversely extending upper and lower edges. First and second gusset panels each have transversely extending upper and lower edges and upright longitudinal outer edges connected to the longitudinal edges of the face panels. A reclosable fastener strip extends continuously and transversely along the first gusset panel and inward along each of the face panels from the first gusset panel along part of a transverse width of the face panels. Thus opening of the fastener and folding out of the first gusset panel forms a spout on the bag. A separate generally rectangular floor panel is joined at its outer edge by thermal welds to the lower edges of the face panels and of the gusset panels.

    Abstract: A method of manufacturing a flat bottom pouch from a single continuous sheet of webbing comprises unwinding the continuous sheet of webbing and forming an outwardly extending transverse lap seam. The unwound webbing is asymmetrically folded to form a folded sheet defining front and back panels. The folded sheet defines a first section and a second section having a folded edge therebetween, wherein the first section includes a first distal edge, and wherein the second section includes a second distal edge. The folded edge is pushed between the first and second sections to form a first side gusseted panel. A portion of the second section is folded between the first and second sections to form a second side gusseted panel. A transverse end seal is formed proximate the lap seam thereby defining a bottom gusseted panel and the first edge is sealed to the second edge to complete the pouch.

  • Publication number: 20140364292
    Abstract: A plastic or other film bag is formed from a continuous extruded tube. The tube is flattened and sealed across its width at intervals to form bag bottoms. The bags are joined to one another at a perforation line and folded in thirds lengthwise prior to being rolled into a compact roll, either with or without supporting core. After folding the bags may be chisel cut through the center of the perforation line to assist in dispensing of the bags. The chisel cut will extend through all layers of the bag when folded, resulting in three chisel cuts in the bag. The bags may be gusseted for part or as much as all of their width. The bags may also be corona treated and printed on their outer surfaces. The bags may be formed from partially recycled materials and various combinations of linear low density, medium and high density polyethylene.

    Abstract: An apparatus for the dimensionally accurate cutting of a product carrier (1) which is in the form of a strip, is transported further in a cyclic or continuous manner in the longitudinal direction and has cells which are arranged one behind the other and are sealed in an airtight manner comprises a rotating cutter roller (15), which severs the product carrier (1) in each case in the region of a sealing web (4) which is situated between two cells (2), is arranged transversely with respect to the longitudinal direction and is provided with a lattice-like embossing (19). In order to identify and localise the sealing web (4), an optical reflection sensor (6) is arranged above and/or below the product carrier (1) and generates an AC voltage signal which corresponds to the lattice structure when the sealing web (4) is located in the region of the reflection sensor (6), the number of periods being a measure of the width b of the sealing web (4).

  • Patent number: 5830118
    Abstract: Longitudinally spaced pairs of laterally spaced openings are formed in a web of material prior to the web being folded into a pouch having a gusset bottom, the holes enabling the side panels of each pouch to be heat-sealed directly together at the side margins of the pouch and in the area of the gussets. To enable the lateral spacing between the openings of each pair to be easily changed and to enable the openings to be located extremely close to the longitudinal centerline of the web, the openings are formed by punches supported by separate punch frames which may be independently adjusted in a direction laterally of the web. The punch frames also are adjustable relative to one another in a direction longitudinally of the web in order to enable the machine to make pouches of various widths.

  • Patent number: 5800325
    Abstract: A pouch making machine which simultaneously creates perimeter seams for a plurality of pouches on a web and temporarily stores the seamed web in an accumulator at the conclusion of the seaming step, and then withdraws the web from the accumulator to sever the individual pouches from the web. The withdrawal of the web from the accumulator is carried on independent of the seaming step, except that regulating means is included to make the long term average web speed the same through the seaming step and the cutoff step.

  • Patent number: 5785794
    Abstract: An apparatus for indexing a seal roll which is engagable by a heat seal head to prevent the contact area of said heat seal head from successive landing at the same location on the seal roll includes a driven pulley mounted coaxially with the seal roll and components for indexing to turn the driven pulley. The components include a rocker mounted on a common axis with a drive pulley via a one-way clutch and an actuator connected eccentrically to the rocker such that reciprocating motion of the actuator rotates the rocker in opposite directions. In one direction, the rocker rotates the drive pulley via the one-way clutch to index the roll via the drive belt and driven pulley. In an opposite direction, the clutch permits rotation of the rocker in the opposite direction free of rotation of the drive pulley. A brake member is connected to the rocker eccentrically of the common axis, the brake member clamping the drive belt against a stop member for seizing rotation of the roll during the heat seal procedure.

  • Patent number: 5683340
    Abstract: There is provided a thermoplastic film bag having at least two integral members that facilitate opening the bag. The bag is manufactured from a flattened tube of thermoplastic material which may be distinctively severed along independent phase shifted sinusoidal oscillating paths down the center of the collapsed tube. The bag may have two opposed tie members which are offset from the vertical center axis of the bag and from each other. The tie members may be grasped and pulled apart to facilitate the easy opening of the bag. The tie members may then be tied together to form a strong member by which the bag may be picked up and carried. In alternate embodiments the shape of the integral tie members can be modified to create a bag having only the easy open feature with no tie members. A method for making the bag is also described.

  • Patent number: 5514067
    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.
