A method and apparatus for making bags is disclosed. It includes receiving a film and imparting a plurality of successive seals to the film to form bags. The location of the imparted seals is determined by monitoring at least two sensors. A plurality of perforations are imparted to the film at locations relative to a corresponding seal in response to the determination. The position of a perforator such as rotary position, of a knife may be controlled in response to determining the location. The seals may be formed by a rotary drum, and the perforation by a rotary knife. The sensors may be at the same or different cross machine direction and/or machine direction locations. Startup may include adjusting and recording the position of a prior perforation relative to a prior corresponding seal, and using that recording as a base relative location in another embodiment.
A method and apparatus for making and winding bags is disclosed. The bag machine includes an unwind section, a forming section, and a winder. The winder has an infeed nip and two spindles. Each spindle is located along a respective one of two alternative film paths. The spindles can be fixed position spindles and the alternative film paths can be predominantly downward. An over speed nip may be provided between the infeed nip and the alternative film paths to separate rolls or to separate all bags. An overlapper can be included. Rods that travel in an elliptical orbit, and/or air nozzles can be part of the overlapper. Air nozzles can also be used to direct the film to the appropriate alternative path. Conveyor belts along the alternative film paths can be used to guide the film. Static pinners can be used to help bold the bags to the conveyor, or the last bag to the roll. Pop-up fingers and air horns can help start the roll on a spindle. Paper banders can be use, as can pneumatic devices. A push off device that scrape the spindles over substantially 360 degrees can be used.

A method and apparatus for continuously or intermittently and vertically forming, filling and sealing packaging includes an i&agr;feed section, a pleating assembly, a forming tube and a sealing assembly. The pleating assembly imparts at least one pleat to the film. The film may be driven and measured at a nip following the pleating. The forming tube receives the film from the infeed section after the pleat has been made. A film tube is formed about the forming tube. The film tube is vertically fed downward to the sealing assembly which imparts seals to the film tube, thereby forming packages. A hole punch punches holes in the film tube. The film travels a film path that includes the hole punch, the forming tube, the vertical seal assembly and the horizontal seal assembly.
