1. A web-cutting mechanism comprising
a housing located upstream in a direction of motion of a web from a web roll that winds the web thereonto;
a slide mounted in the housing, the slide guiding a shuttle assembly having a blade, in a cross-web direction that is transverse to the direction of motion;
a blade driver that selectively biases the shuttle assembly so that the blade engages into a side of the web while tensioned between the web roll and an upstream location;
a release that receives a signal indicating a condition in which separation of the web is desired, and in response thereto, allows the shuttle assembly to be biased by the blade driver; and
wherein the blade is oriented at an angle with respect to the direction of motion that induces a cross-web component of force in response to web motion that moves the blade and shuttle assembly at least part way in the cross-web direction.
