Package wrapping apparatus which has a wrapping table and a roll film stand is provided with a cooperating knife blade and web snubber to sever the web into lengths appropriate for wrapping the package. The web snubber and knife blade are mechanically actuated in time with the wrapping sequence under pressure of the package which is undergoing wrapping on the apparatus. The web severing tool parts are provided with motion transmitting linkages to a movable frame having a package rest. The movable frame is shifted under pressure of the package, thus to actuate the linkages and sever the web.
