    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.
