Abstract
Stripping apparatus for stripping copy sheets bearing electrostatic developed images from a heated pressure fusing roll after fusing of the images to paper sheets. The stripping apparatus comprises a flexible blade member supported by a retaining device and positioned into contact with the heated fusing roll surface. The tip of the blade has a hollow ground edge of a radius slightly greater than the fuser roll. The blade is slideably positioned to enable lateral expansion axially relative to the retaining device. A modification of the stripping device consists of a comb design with blade and retaining members having inter-locking tines.
Claims5
In an apparatus for contact fusing toner particles to paper support material wherein said apparatus comprises fusing roll for applying heat and pressure to the particles and paper support material at a nip through which they are passed therethrough, an improved stripping apparatus for stripping sheets from the fuser roll surfaces comprising:
- blade retaining means positioned in close proximity to a fuser roll surface from which copy sheets are to be stripped,
- a flexible blade member supported by said blade retaining means at an angle of about 20.degree. to 30.degree. to the fuser roll surface longitudinally coextensive therewith,
- said blade member having a hollow ground edge at the tip thereof of a radius slightly greater than the fuser roll surface,
- wherein said blade retaining means and blade member are arranged with inter-locking tines.
