Abstract

A stripping blade for stripping paper or other substrates from a cylindrical imaging surface, is mounted at a skewed angle to make tangential contact at one end of the cylinder outside of the imaging area to avoid contact with the imaging surface and with any toner (liquid or dry powder) deposited in the imaging area. This design provides a given length of blade edge ex-tending from the point of contact over the imaging surface where the blade edge is sufficiently close to the imaging surface to strip the sheet therefrom.

A stripping blade for stripping paper or other substrates from
a cylindrical imaging surface, is mounted at a skewed angle to
make tangential contact at one end of the cylinder outside of
the imaging area to avoid contact with the imaging surface and
with any toner (liquid or dry powder) deposited in the imaging
area. This design provides a given length of blade edge ex-
tending from the point of contact over the imaging surface
where the blade edge is sufficiently close to the imaging
surface to strip the sheet therefrom.

The stripping of sheet material from the surface is initiated
at one corner of the sheet material and progresses along the
lead edge of the sheet material to the other corner of the
sheet material, Floating contact of the stripping blade
follows the runout of the imaging drum. The stripping blade

can extend the entire width of the surface from which sheet
material is stripped, or it can extend only a fraction of the
width of the surface.

SKEWED BLADE STRIPPER (Cont'd'

The blade stripper is illustrated in the drawing. Drum 1
having imaging surface 2 is advanced in the direction of arrow
3. A sheet of paper 4 on imaging surface 2 is stripped from
imaging surface 2 by skewed blade stripper 5 at the leading
edge corner of the sheet designated by numeral 6 in the area on
surface 2 where blade stripper 5 is in floating contact with
surface 2. This point of floating co...
