Abstract: In a film supplying device in a package machine, a film drawn out from a film roll is fed downstream between a drive roll and a driven roll. The drive roll is rotatably supported by a first support fixed to a main frame. A second support for rotatably supporting the driven roll is supported on the main frame so as to be rotatable. The second support is movable between a sandwiched position where the driven roll approaches the drive roll to be aligned therewith to hold the film therebetween, and a retract position in which the driven roll is spaced apart from the drive roll.

Abstract: A conveying apparatus includes a circulation track and a plurality of travelers movable along the circulation track under a control of a controller for conveying articles. If no preceding article-conveying traveler exists on the front side of one of the travelers planned for receiving and conveying the article detected by a detection section, the planned traveler serves as a no-article conveying traveler, and the other traveler located adjacent the planned traveler serves as an article conveying traveler.

The system further includes a connecting device to connect the film leading end of the second roll film to the film terminal end of the first roll film. The robot to move the second roll from the connecting position to a set position after connecting the films, so that the second roll film is tensioned.

Abstract: In a film supplying device in a package machine, a film 12 drawn out from a film roll is fed downstream between a drive roll 32 and a driven roll 34. The drive roll 32 is rotatably supported by a first support 38 fixed to a main frame 26. A second support 56 for rotatably supporting the driven roll 34 is supported on the main frame 26 so as to be rotatable. The second support 56 is movable between a sandwiched position where the driven roll 34 approaches the drive roll 32 to be aligned therewith to hold the film 12 therebetween, and a retract position in which the driven roll 34 is spaced apart from the drive roll 32.

Abstract: A form-fill sealing machine (1) for manufacturing resealable packages (W) includes a tearable line forming device (30) that serves to form tearable lines (104) in a film (F). A labeling device (40) serves to stick re-stickable labels (103) onto the film in positions to cover respective tearable lines. A tube forming device (60) serves to form the film into a tubular film (T). A first sealing device (80) serves to seal lapped edges of the tubular film so as to form a lengthwise sealed portion (111). A second sealing device (90) serves to seal the tubular film in a crosswise direction, so that crosswise sealed portions (109) are formed on the tubular film. Each tearable line is positioned between two adjacent crosswise sealed portions and adjacent to one of two adjacent crosswise sealed portions.

Abstract: Disclosed is a process and an apparatus for assembly-packaging pellet-like articles in units of a predetermined, characterized in that a pellet-like articles group is ejected toward a packaging film locating at a stand-by position to be gripped together with the packaging film half-wrapped around the pellet-like article group by an article holding means; overlapping edges of the packaging film gripped by the article holding means are put together and preheat-seated, followed by sealing thereof to form a sealed rib; the sealed rib is folded down along the barrel of the pellet-like article group and heat-sealed; each open end portion of the tubular packaging film is gussetted and partially sealed; the gussetted and partially sealed portions are sealed fully to form sealed tabs, and the unnecessary portions of the tabs are cut off; and the sealed tabs are folded down along end faces of the assembled pellet-like article group and heat-seated.

Abstract: A waste disposing system and apparatus are described which use inverted conical frustum cup-like containers of paper or synthetic resin with brims having an adhesive applied thereto, said apparatus comprising: a container supplying means for holding a stack of containers having a top and a bottom, and formed by one sliding over another, and releasing, in response to a request, one after another, from the stack of containers, permitting the falling of a sequential container that has descended down to the bottom of the stack for its turn; a standby means for holding the container with the open side thereof up, thereby permitting the filling of waste into container on standby; a sealing means for pressing the top circumference of the container which is filled with waste to seal the container; and a carrier means for transporting containers from the container supplying means to the standby means, and from the standby means to the sealing means.

Abstract: A horizontal form-fill-seal packaging machine includes a former for forming a film into a tubular configuration, a conveyor for feeding articles into the tubular film one after another, a fin sealer for sealing lapped edges of the tubular film, an end sealer for sealing the tubular film in a crosswise direction thereof in a position between two adjacent articles, and a film feeding mechanism for feeding the film supplied from a film source into the end sealer via the former and the fin sealer. A plurality of pushers are mounted on the conveyor and equi-distantly spaced from each other in the feeding direction of the articles. Each of the pushers defines the position of a rear end of the article. A length detector sequentially detects the length of the articles in the feeding direction. A controller controls the conveyor and the end sealer in response to the length of each article detected by the length detector.

Abstract: Disclosed herein is a device for sealing portions of an overlapped pair of single or composite films by contacting or facing an appropriately heated sealing surface of a heat sealing member.
