摘要： PROBLEM TO BE SOLVED: To prevent a plastic material from remaining stuck to sealing dies without moving the material from a seam region during a sealing operation by simultaneously cooling a region adjacent to a plasticized region for forming a heat sealed joint while a sealing heat is supplied. SOLUTION: In the case of heat sealing two films 12, 13, the films are desirably polyolefin films, and sealing dies are urged to the films 12, 13 in a direction of an arrow F. While the sealing heat is supplied, heated regions 14 of the films 12, 13 are formed in intermediate regions of sealing dies 1, 2. The films are melted in the heated regions, and heat sealed to one another. The regions 14 are surrounded by a cooling region 15. And, when a joint is once formed of the regions 14, the supplied heat is rapidly fed out from the region 15. As a result, the joint is quickly cooled as desired.

摘要： PROBLEM TO BE SOLVED: To provide an automatic sealing device capable of positioning a bag mouth to be sealed relative to a sealing machine even when a packaging bag is fed easily in a manual or mechanical manner. SOLUTION: Two conveyor belts 33, 34 are arranged in V-shape as a carrying machine 11 to carry a packaging bag X. When the packaging bag X is feed on the belts 33, 34, a lower end part of the bag X is abutted on one belt 34 by the self-weight of the bag, and a side part of the bag is abutted on the other belt 33 in a natural posture. A bag mouth at the upper end part of the packaging bag X can be positioned contact relative to a pressing base 61 or a heating base 62 of a sealing machine 41, and the defective seal can be avoided.

摘要： PROBLEM TO BE SOLVED: To independently control a seam from a welding device and securely detect even a little leakage from the seam, by controlling the seam by a light- transmission method by use of a pack belt material provided with a transparent support layer and a collored seal layer. SOLUTION: In a pack belt material 11 composed of a transparent and nonmolten support layer 14 and a colored seal layer 15 covered with the support layer 14, a lateral seam 16 is formed by a welding machine 17 provided with heatable seal jaws 18, 19 and the middle part is cut by a cutter knife 23 to make a pack 12. The separated pack 12 is transferred to a control device 30 by a belt conveyor 26. The lower side of the lateral seam 16 is irradiated by a light source 33. The light which has passed through the lateral seam is detected by an optical sensor 32 arranged at the upper side and compared with an aimed value stored in the controller 30 to evaluate the quality of lateral seam 16 and further fed back to the control device of the pack producing machine.
