摘要： PROBLEM TO BE SOLVED: To join together wrapping materials fluid-tightly, by superimposing the wrapping materials, each comprising a thermoplastic material layer, conductive material layer, and fiber material support layer bonded together, by heating and melting the thermoplastic material layers by the application of a high-frequency current to the conductive material layers from a seal jaw, and by partially pressing seal zones with a projection sticking out from the pressed face of the seal jaw, thereby causing the melted material to flow. SOLUTION: While a high-frequency current is applied to a conductive projection sticking out from the surface of a seal jaw 5, this projection is pressed to an area where laminated wrapping materials 10 and 11, each comprising a thermoplastic material layer 3, a conductive material layer 4, and a fiber material support layer 1, are superimposed one on top of the other, thereby heating and melting the thermoplastic material layers 3 via the conductive material layers 4. Further, because the middle areas of the seal zones 13 and 14 are partially pressed with the projection, the melted thermoplastic resin material layers 3 flow to sweep away foreign matters, for example minute dust, from the surfaces of the conductive material layers 4, eliminating the foreign matters mixedly existing between the conductive materials 4 and improving their contact, and the hermetic joining of the wrapping material layers 10 and 11 is, thus, made easy and sufficient.

摘要： PURPOSE: To seal a tubular packaging material quickly and successively by providing a pair of sealing jaws and another pair of sealing jaws placed on the opposite side and shifted by 180 degrees. CONSTITUTION: A pair of sealing jaws 81 and 81' and a pair of separate jaws shifted by 180 degrees with respect to the sealing jaws are provided with an laterally extended arms 471/471' and 472/472'. A tubular sealing material 7 formed to a rectangular shape is sealed by forming flaps 91/91' and 92/92', formed by sealing bars 361/361' and 362/362' provided on the arms 471/471' and 472/472'. Thus when the tubular sealing materials alternately seal with sealing bars 361/361' and 362/362', two pairs of sealing jaws 81/81' and 82/82' can cross and pass unhindered by the other, thus permitting high-speed and successive forming.

摘要： PROBLEM TO BE SOLVED: To prevent a content from being absorbed in the area around a pouring port, and also, provided a high gas shielding property by a method wherein for the pouring port, a seal is formed around the pouring port between a cover strip and an external thermoplastic layer while remaining a bonding under a water-proof state on the confronted and joined thermoplastic layers. SOLUTION: Thermoplastic layers 3, 4, 6 of a pack laminated material, are bonded to each other under a water-proof state, and for this reason, the thermoplastic layers 3, 4, 6 form a seal 11 around a pouring port 7 without covering the pouring port 7. By this seal 11, the thermoplastic layers 3, 4, 6 totally cover the edge 12 of a carrier layer 2 facing the direction to the pouring port, and in addition, seal the edge 12. Also, when the seal 11 is formed in the direction to a cover strip 8, around the cut edge 12, a gas shielding layer 5 is bent together, and is completely enclosed in the thermoplastic layers 3, 4, 6 being sealed to each other. For this reason, the waterproofness and the gas shielding property of this pack container can be improved in the region of the opening structure.

摘要： PURPOSE: To produce laterally well-sealed parallelepiped packaging container by engaging hook-shaped members with each other while sealing bars hold a tubular packaging material, and by imposing necessary pressure to a lateral seal with a piston cylinder unit through a hook-shaped member. CONSTITUTION: A hook-shaped member 40 is lifted by a cam 42 and is swiveled inward with a sealing bar 36', and engages with a cooperating hook-shaped member 39 while the sealing bars 36 and 35' are in lateral sealing position. After completion of the engagement, a piston cylinder unit 41 presses the hook- shaped member 40 to a farther side from the hook-shaped member 39. It produces a desired compression between two sealing bars 36 and 36', and imposes a pressure on the lateral seal through the engaging hook-shaped members 39 and 40. Thus good lateral sealing is achieved even at continuous high-speed operation of the apparatus.

摘要： PURPOSE: To produce a laminated sheet material for packaging food having a layer of an aluminum foil and preventing the elution of an oxidation product into food from the layer of a synthetic resin material provided in the inner surface of the layer of the aluminum foil and excellent in the preservability of food. CONSTITUTION: A molten synthetic resin material 3 is injected into the gap between a base material 1 and an aluminum foil 2 and a blown film 7 is supplied to the inner surface of the aluminum foil and the whole is pressed by rollers to be integrated. At this time, the blown film 7 is fused by the heat of the molten synthetic resin material 3 to become a laminated sheet material. The blown film supplied to the surface of the aluminum foil is molded within a low temp. region not generating oxidation product and has a plurality of layers 7', 7" therein. By this constitution, there is possibility such that the oxidation product is generated only in the layer 7' facing to the aluminum foil and the generation of the oxidation product in the innermost layer 7" coming into contact with food can be prevented.

摘要： PURPOSE: To prevent the dewing phenomenon on the surface of a mandrel and to eliminate the seal inferiority of the bottom part of a container caused by mandrel cooling inferiority by allowing cooling water to flow through the mandrel in a circulative manner while controlling the temp. thereof so as to hold the surface temp. of the mandrel to a temp. range from the dew point to the coagulation temp. of a thermoplastic material. CONSTITUTION: The temp. of cooling water supplied and circulated to a mandrel 1 for forming a bottom part, a bottom part pressing member 12 and a bottom part folding plate 13 is controlled by detecting the temp. of cooling water raised in temp. by the heat exchange with the bottom part heated, folded and bonded under pressure at a time of the formation of the bottom part of a container by the pressure bonding from a cylindrical packaging container material C by a container bottom part forming device to reflux to supply secondary cooling water to cooling water at a proper time and holding tertiary cooling water to a temp. range from the dew point to the coagulation temp. of a thermoplastic material. The cooling water overflowing from the piping line of tertiary cooling water when the secondary cooling water is supplied is refluxed to the connection pipe 26 of the piping line of secondary cooling water from a piping 22a. Therefore, during the sealing process of the bottom part of the packaging container material, the side wall of the mandrel main body part is cooled to temp. equal to or higher than the dew point.

摘要： PURPOSE: To perform accumulating work for plural articles of different sizes with a single device by setting a starting position and a stroke of a pusher to be changeable, corresponding to a moving position of a vertical conveyor. CONSTITUTION: Since articles are carried in order by a carrying conveyor 1, the carried articles are stopped by stopped vertical conveyors 2, 3. After that, the vertical conveyors 2, 3 are driven to feed a specified number of the articles forward, the articles fed forward are finally stopped to be pushed and arranged in a line on the carrying conveyor 1. In this condition, a pusher 4 on one side is actuated to be driven across the carrying conveyor 1, so that the articles arranged on the carrying conveyor 1 are pushed toward the other side. By repeating this operation a prescribed number of times, the desired accumulation of the articles can be performed.
