  • Patent number: 4335634
    Abstract: A web severing device has a pair of spaced-apart carriages straddling the path of the web, a severing blade being attached to one of the carriages. Power devices are provided for moving the carriages toward each other to bring the blade into severing contact with the web. Resilient devices are provided to prevent activation of the severing blade if a relatively rigid foreign object such as a human finger is accidentally embraced between the carriages and to prevent injury. When only the web is disposed between the carriages a portion of the resilient devices also functions to urge the blade-carrying carriage into web severing contact.
