and apparatus for removing an adhesive film from a substrate. Appellants
indicate that the disclosed apparatus is useful for removing an adhesive film
from a substrate having a large area, such as a building or a side of a truck,

substrate, the apparatus comprising:
a winding roll attached to a frame, the winding roll
comprising a longitudinal axis;
a motor operably connected to the winding roll for
rotating the winding roll about its longitudinal axis; and
a support roll rotatably attached to the frame, the support
roll located a fixed distance from the winding roll, wherein the
winding roll and the support roll are arranged on the frame such that
tension applied to an adhesive film during removal of the adhesive
film from the substrate is transferred to the substrate through the
support roll, and wherein the support roll is not located at a release line of
the adhesive film.
