| 1 | Uninterrupted bag making machine | US14267062 | 2014-05-01 | US09688043B2 | 2017-06-27 | Chun Liang Lin |
| An uninterrupted bag making machine includes a conveyance unit, a conveyance unit driving means, a sealing unit having sealing assemblies, a sealing unit driving means, a perforating unit having a cutting device, a perforating unit, a perforating unit driving means, a breaking unit, and a control unit. With the conveyance unit, a film tube is conveyed to pass through the sealing unit, the perforating unit, and the breaking unit. Furthermore, with the control unit in cooperation with various driving means, the sealing assemblies can be moved in the direction of the film tube being moved, and the cutting device of the perforating unit is rotated in synchronous with the film tube being moved. As such, the film tube can be processed with sealing operations, perforating operations, and breaking operations at predetermined locations along the film tube without an interruption, so that the production rate and capacity can be increased. | ||||||

| 3 | Continuous heat sealer for sacks and bags in thermoplastic material | US372444 | 1982-04-27 | US4537585A | 1985-08-27 | Rodric H. Norman |
| An apparatus for heat sealing of plastic bags having a main assembly for sealing, which includes drive and control means and a removeable heat sealing head having confronting heat transfer means between and in contact with which the bags pass, such that confronting side walls thereof are heat sealed, the heat sealing head constituting a sub-assembly provided with its own drive means and adapted to be received in said main assembly through a single drive means. | ||||||
| 4 | Apparatus for distributing continuously supplied tube sections to three production lines for making sacks | US298586 | 1981-09-02 | US4452443A | 1984-06-05 | Fritz Achelpohl |
| Flattened tube sections for making sacks are continuously supplied by a main conveyor and selectively fed longitudinally to one of a plurality of connecting conveyors leading to respective production lines along which the sections are moved transversely after turning by respective turntables. The connecting conveyors for the second and subsequent production lines receive their tube sections from an intermediate conveyor. A deflector is pivotable between the intermediate conveyor and the connecting conveyor for the first production line. | ||||||
| 5 | Bag making machine | US924133 | 1978-07-13 | US4240336A | 1980-12-23 | John J. Grevich; Stanley D. Denker |
| A bag making machine continuously drawing and propelling tube stock from a supply in a roll, including an in-feed conveying mechanism having feed rolls drawing the tube stock from the supply, a horizontal belt conveyor with spaced individual belts carrying the tube stock in horizontally laid out condition, a continuously moving cutter mechanism including clamping jaws above and below the tube stock on the belt conveyor, the lower jaw having slots receiving the belts therein, the upper and lower jaws having stationary and yieldable jaws to grip, clamp and stretch the film, and the upper jaw having a cutter moving downwardly in a slot into a corresponding slot in the lower jaw; a crimper to longitudinally corrugate the tube segments severed from the tube stock and shoot the severed tube segments across the receiving end of a crossfeed conveyor mechanism which changes the direction of the tube segments, the crossfeed conveyor mechanism including a roller conveyor to receive and carry the tube segments transversely from their first direction of movement, weighted balls aligned along adjacent ends of the rollers in the roller conveyor; a moving fence against which the edges of the bags engage at the crossfeed conveyor, the crossfeed conveyor mechanism also having a belt conveyor with spinning balls superposed above belts at the edges of the tube stock and guiding the tube stock into a high speed sealer along one side of the belt conveyor, and the belt conveyor supplying the bags formed from the tube stock into superposed upper and lower stacking conveyors alternately directing a number of bags onto accumulating conveyors. | ||||||
