<p>SHEET FEEDING APPARATUS In order to strip sheet material from an arcuate surface, a stripping element is provided that has bearing surfaces adjacent its leading and trailing ends arranged to be pivotably connected to a support element at a first pivot point that is equidistant the bearing surfaces. The support element is pivoted at a second pivot point and urges the stripping element towards the arcuate surface. The first pivot point lies at a tangent of the arcuate surface originating opposite the leading edge when in use. The second pivot lies at a line extending through the leading edge and the first pivot. Accurate juxtaposition with the arcuate surface of the leading edge of the stripping element can be achieved even if the arcuate surface moves radially to some extent as it moves past the stripping element.</p> |
