JPS6438221A - Continuously filling packer - Google Patents

Abstract

PURPOSE:To heighten the productivity of a packer by a method in which a zipper and contents are fed into between the films for front and rear, and then the zipper is stuck to both films for front and rear and is fixed thereto, and further the films for front and rear are cylindrically sealed on both sides thereof and the planned position for cutting having been flattened by flattening the zipper is sealed. CONSTITUTION:A film 1 is cut into two sheets by a triangular plate X and then they are overlapped mutually and are transferred. In between the films 1a, 1b, a zipper 2 and contents 3 are respectively fed so as not to overlap mutually and are transferred at a same speed. Then, the contents are softened by heaters 41, 41, 42, and while the zipper 2 is stuck to both films 1a, 1b by a nip roll 52, the both sides of the film 1a, 1b are cylindrically scaled by nip rolls 51, 51. Next, the films having received with contents are nipped by a driving belt 6 and are transferred, and then by the roll 7 for zipper flattening, the zipper 2 is flattened at the planned position for cutting by heating and pressurizing. This planned position for cutting is mutually scaled by scaling bars 8, and then a packed object 10 is obtained by cutting said films by cutters 9. Consequently, the packed object of the bag with a zipper is continuously produced, while the packing of the contents and the making of bags are continuously and consistently achieved.
