Abstract

A web severing device for providing a smooth severed edge on a moving web. The device includes a support member and a plurality of independent blade sections mounted on the support member at substantially a 45° angle with respect thereto. In one embodiment, a forward portion of each of the blade sections is angled toward a center of the support member whereas in a second embodiment, the blades are alternately angled toward and away from the center of the support member. In all embodiments, the support member is selectively released toward the web, and the plurality of blade sections simultaneously engage with the web to sever the same.
