  • Method for encapsulating articles in wicketed bags
    Patent number: 5467578
    Abstract: A wicket of bags such that the bags are releasably secured to a header by release lines. Each bag has a front and back side, side edges, a bottom edge and inner and outer surfaces. The outer surface of the back side of a first bag is adjacent to the outer surface of the front side of the next succeeding bag. A sealed pocket is formed on the outer surface of the front side of a bag and is adapted to have an article encapsulated therein.

  • Method and apparatus for manufacture of wicketed bags with an encapsulated article and the bags formed thereby
    Patent number: 5249409
    Abstract: A wicket of bags are joined to a common header. Each of the bags has an open pocket formed on the front side. The bags are placed front side down on a support surface. The top most back of the wicket is turned over to expose the front side while being transferred to a sealing station. The sample is placed in the pocket, the pocket is sealed and the bag removed. The remaining bags of the wicket are filled with samples in a similar manner. These steps are accomplished without removing any of the bags from the common header.

  • Flexible bag with article encapsulated on one side thereof
    Patent number: 5228268
    Abstract: A system and method for encapsulating three dimensional articles on one side of a bag formed by a bag making machine. A conventional bag making machine is modified configuring the drawrollers to allow for passage of the three-dimensional article. Additionally, a feeding station is used which acquires the article, moves the article to a gluing station where an adhesive is applied to the article. The feeding station then moves the article into a fold formed in the bag. The fold is sealed and the bag subsequently formed.

  • Method for forming angular seals in side-gussetted bags
    Patent number: 4986804
    Abstract: Seals are formed in bags made from a flexible web. The sealing element is a heated wire. The thermal conductivity of the wire is selected in reference to the melt and tack characteristics of the film being sealed such that when the film is placed in heat-exchange relationship with the wire, the film is sealed. Further, at least a portion of the film travels on the sealing element. The resistance across the sealing element remains constant during sealing and while the web travels sequentially.

  • Apparatus for the manufacture of block-sealed side-gussetted bags
    Patent number: 4946431
    Abstract: A method for making block of side-gussetted, bottom-weld bags. Each bag has an opening on one side to fascilitate the removal of individual bags from the block.

  • Sealing element for angle seals and T-shirt bags
    Patent number: 4895556
    Abstract: Seals are formed in bags made from a flexible web. The sealing element is a heated wire. The thermal conductivity of the wire is selected in reference to the melt and tack characteristics of the film being sealed such that when the film is placed in heat-exchange relationship with the wire, the film is sealed. Futher, at least a portion of the film travels on the sealing element. The resistance across the sealing element remains constant during sealing and while the web travels sequentially.

  • Apparatus for the manufacture of block-sealed side-gussetted bags
    Patent number: 4767391
    Abstract: Bags are manufactured from a tubular web of thermoplastic film. An air injector periodically inflates the film whereupon it contacts cooperating vacuum plates. One of the plates has a cutting die which cuts a tab in the film which in turn provides an ingress for the injected air. The film is then sealed and severed to form the bags, which are then formed into a block. The tab then serves as an opening to facilitate the removal of individual bags from the block.

  • Block-sealed flexible saddle bags
    Patent number: 4733780
    Abstract: A block of paired, side-gussetted, bottom-weld bags. Each bag has an opening on one side to facilitate the removal of individual bags from the block.

  • Apparatus and method for forming apertures in film materials
    Patent number: 4559199
    Abstract: A continuous tubular film passes through two opposed vacuum plates. One of the vacuum plates has a heated die formed therein. The film is pillowed and a portion contacts the die. A section is cut from the film and removed and, subsequently, the pillowed film is deflated. These steps are repeated in timed sequence. The apparatus and process allows the forming of apertures or sections in one side of a tubular film alone.
