    摘要： 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.

    摘要： This invention pertains to apparatus and methods for breaking a web along spaced lines of weakness. The invention includes a compact breaker bar assembly comprising at least one breaker bar in a gap. The apparatus also includes driving apparatus to power the breaker bar assembly in breaking the web. In some embodiments, one or more breaker bars engage and stress the web along a single transverse line across the web, breaking the web. In other embodiments, at least first and second breaker bars engage and stress the web along spaced first and second transverse lines across the web. The breaker bars can be mounted on one or more rotary elements, or can be mounted on one or more belts or other breaker bar carriers, traversing closed-loop paths. In preferred embodiments, the breaker bar assembly comprises at least two breaker bars, a first breaker bar following a first straight-line path segment while a second breaker bar follows a second opposing straight line path segment, both breaker bars engaging and stressing the web at the same time, both breaker bars following the straight-line path segments before engaging the web, during engaging and stressing of the web, while breaking the web, and after breaking the web.
