1. A web handling device comprising:
an input roller that receives web on a feed path from an upstream handling device;
a web output member that is driven to receive the web; and
an emergency stop cutting mechanism located between the input roller and the output member that, in response to a stop signal, releases a blade oriented at a non-perpendicular angle to a feed direction of the feed path along a cross-web direction, wherein the blade is engaged with the web in motion, and the blade is biased across the web to separate the web by drawing of the output member.
