An apparatus for manufacturing a stick container having a pair of filler accommodating parts by processing a sheet-shaped material, the apparatus comprises: a lengthwise sealing unit that bonds side surfaces of the material to each other in order for the material to have an internal space which is elongated in a lengthwise direction; a widthwise sealing unit that bonds the material to separate the internal space along the lengthwise direction; and a filling unit that is configured to fill a first filler and a second filler in the separated internal spaces, respectively, wherein the widthwise sealing unit includes: a top and bottom surface sealing unit that bonds a bottom surface of the stick container where the first filler is to be filled and bonds a top surface of the stick container where the second filler has been injected; and a separation surface sealing unit that bonds a central portion of the stick container after the first filer is filled and before the second filler is filled.

A method and apparatus for producing product packages comprises operating first and second feedback control loops where product package weight is averaged and used to determine one of two possible adjustments to change the product fill rate and the volume of the product. The feedback loops operate in one of a plurality of index levels. The first feedback loop seeks to improve performance by making adjustments to the fill rate and volume of the product, while incrementally moving to more stable index levels requiring tighter tolerances and package weight averages based on more product packages. The second feedback loop seeks to preserve stability by making its own adjustments to the fill rate and volume of the product if large product package weight fluctuations are sensed. The second feedback loop can move operation to less stable index levels having wider tolerances and package weight averages based on fewer product packages.

Providing a packaging machine and a sealing method in the packaging machine both of which can reliably seal a packaging bag in a good-looking finish without forming large bubbles on a seal inner surface of a bag mouth of the packaging bag and/or creases on a seal part. A packaging machine includes a seal part preheating station for preheating a seal part of a packaging bag after the packaging bag has been filled with an article and steam deaeration has been carried out, a decorative seal applying station provided downstream of the seal part preheating station for applying a decorative seal to a part of the packaging bag above the seal part and an ultrasonic seal applying station provided downstream of the decorative seal applying station for applying an ultrasonic seal to a part of the packaging bag A below the seal part.

A vacuum sealer for vacuum packing products in plastic vacuum bags includes a sealing bar and a lift mechanism configured to raise and lower the sealing bar. In the raised position, the sealing bar is configured to engage and compress the vacuum bag against a compression bar. The vacuum sealer include a vacuum pump that is operated to draw a vacuum in the vacuum bag. The sealing bar includes a heating element that is configured to heat the sealing bar when energized. Once the vacuum is drawn in the vacuum bag, the sealing bar is heated and the heat is applied to the vacuum bag, which seals closed the vacuum bag with the product vacuum packed therein. The lifting mechanism lowers the sealing bar to release the vacuum packed product. The vacuum sealer includes a cooling chamber into which the sealing bar is moved when lowered by the lift mechanism. A cooling fan directs convection air through the cooling chamber and over the sealing bar to cool the sealing bar.

Provided are a method and an apparatus for extruding into a tube and filling the tube at a high speed and simultaneously sealing the tube. Specifically provided is a method for producing a polymer tube, containing a liquid therein and being sealed at constant intervals, the method including an extrusion step of continuously melt-extruding a polymer material through a die into at least one tube, while feeding a liquid into the tube to obtain at least one liquid-containing tube; and sealing step of discontinuously pressing the at least one liquid-containing tube between a pair of pressurizing members at constant intervals to cause pressure-bonding before the tube solidifies, while continuously taking up the extruded tube.
