A bag making machine for making bags from a sealable film is disclosed wherein the film is fed over a forming shoulder and around a forming tube. Sealer jaws form a transverse seal to provide a top for one bag and the bottom of the next adjacent bag, and move with the film as it is advanced intermittently along the tube. Separate and independent means are provided to advance the film simultaneously with movement of the sealer jaws, and means are also provided for forming a substantially flat bottom on each bag including a novel arrangement of folding plates for the bottom, tuckers for forming gussets, and creasers for forming creases in the film at the corners of each bag.

Tap attachment means are secured to an elongate web of heat sealable plastics material. The web is formed into a plurality of sealed liquid filled bags, each bag being formed from a length of the web to which is secured a tap attachment means. Each tap attachment means facilitates the draining of the liquid from the bag.

A plastic bag comprises a tubular plastic sheet member having front and rear walls. The upper and lower edges of the front and rear walls are heat sealed in a straight line across the width thereof so as to enclose the sheet member to form a sealed container. A reinforcing seal commences at one of the lateral edges of the container at a point below the straight line seal of the upper edge and continues laterally partially across the width of the front and rear walls and thence upwardly to join the straight line seal at a point spaced laterally inwardly from the other of the lateral edges. A method of the present invention comprises forming a plurality of spaced apart straight line seals across the width of an elongated continuous plastic tube member, forming a reinforcing seal such as described above adjacent each of the straight line seals, placing a grommet in the tube members in the space between the reinforcing seal and the upper straight line seal, and severing the tube member transversely into a plurality of containers with the straight line seals forming the upper sealed edges of each of the containers.

Chub packaging machine wherein the drive motors for the tubeadvancing means, the constricting-closure unit, and the product feed pump, and drive motor for an extruder sealing unit, or the air temperature of a hot-air sealing unit, operate cooperatively whereby all drive speeds change proportionately as the tubeadvancement rate, or sealing air temperature, is changed. The constricting-closure unit and product feed pump drive motors operate also independently for more precise adjustment, preferably through automatic feedback control loops.

High-speed forming of a series of partitioned tubular film packages, e.g., rock bolt resin cartridges, wherein different materials are maintained on opposite sides of a strip-like or tubular partition which is secured to the ends of the package, by forming and advancing a continuous tube of film and advancing a film barrier layer (a strip or smaller-diameter tube) within the advancing tube at substantially the same rate therewith; filling the tube with two different materials on opposite sides of the barrier layer; constricting the tube around the barrier layer at spaced intervals and applying a pair of encircling closure means thereto; and severing the tube between the pair of closure means. Apparatus for advancing and filling nested tubes to produce a tubular package having an inner tubular barrier layer secured to the ends thereof.

A method of and apparatus for packaging a food product wherein a slurry of the food product and a brine solution is used to facilitate the advance of the food product. The slurry is collected in a vessel from which a portion of the food product is removed under pressure and delivered to a bag or pouch-forming apparatus. The brine solution is removed from the food product while it is being delivered to the pouch-forming apparatus but is reunited with a brine solution in the pouch-forming apparatus. The latter also includes means for preventing the food product from being entrapped in the seal area of the pouch which would prevent a satisfactory seal from being formed.
摘要:
A multiple-compartment laminated package is provided which is suitable for holding in separate compartments different substances which can be mixed together within the package upon breaking the barrier between the separate compartments. This barrier can be broken by the application of external pressure to the package which applies tension to an inner layer of the outer wall of the package, such rupture of the inner layer taking place at a controlled location by virtue of a reduction in the bond strength between the inner layer and the next adjoining layer of the outer wall of the package.

CONNECTED PACKAGES ARE FORMED BY A TWO STAGE SEALING PROCESS. A MATERIAL RECEIVING CHAMBER IS FORMED IN THE FIRST STAGE BY COMPLETELY FORMING AN INNER SEAL AND PARTIALLY FORMING AN OUTER PERIPHERAL SEAL. THE CHAMBER IS FILLED WITH MATERIAL SUCH AS COFFEE. THE OUTER PERIPHERAL SEAL IS THEN COMPLETED AS THE FIRST STAGE SEALS ARE MADE IN THE NEXT SUCCEEDING PACKAGE. A SAW TOOTH CUTTER IS EMPLOYED TO WEAKEN THE AREA BETWEEN ADJACENT PACKAGES AND TO COMPLETELY SEVER A PREDETERMINED NUMBER OF THEM.
