Claims
- 1. Apparatus for feeding sheets one at a time to a stop wall at the end of the apparatus, the apparatus comprising movable horizontal support means for said sheets which move from an inlet end to an outlet end of the apparatus where said stop wall is located, at least one overhead support means extending above said movable support means and being bodily supported for individual adjustment transversely of the direction of movement of said support means, a roller carrying sub-assembly supported on each overhead support means for longitudinal adjustment thereon, each roller carrying sub-assembly comprising roller means for making rolling engagement with the sheet of material moving on said support means and positioned to prevent "bounce back" thereof as the sheets are moved against said stop wall, resilient arm means on each sub-assembly and carrying said roller means on the end thereof, means for varying the downward force of the roller means upon the sheet moving on the movable horizontal support means, and pressure band means mounted to said overhead support means and extending above and longitudinally of the movable support means for pressing down upon the sheet material thereon simultaneously with the downward pressure of said roller means thereon.
- 2. The conveyor apparatus of claim 1 wherein there are provided at least two longitudinally spaced roller carrying assemblies supported for longitudinal adjustment on said overhead support means.
- 3. The conveyor apparatus of claim 1 wherein the resilient arm means carrying each roller means is pivotable about a vertical axis between a first fixed position where the roller means is longitudinally spaced from the pivot axis on the upstream side thereof to a second fixed position where the roller means is longitudinally spaced from the pivot axis on the downstream side thereof.
- 4. Apparatus for feeding sheets one at a time, said apparatus comprising movable horizontal support means for said sheets which move from an inlet end to an outlet end of the apparatus, at least one overhead support means extending above said movable support means and being bodily supported for individual adjustment transversely of the direction of movement of said support means, a roller carrying sub-assembly supported on each overhead support means for longitudinal adjustment thereon, each roller carrying sub-assembly comprising roller means for making rolling engagement with the sheet of material moving on said support means, resilient arm means on each sub-assembly and carrying said roller means on the end thereto, said resilient arm means carrying each roller means being pivotable about a vertical axis between a first fixed position where the roller means is longitudinally spaced from the pivot axis on the upstream side thereof to a second fixed position where the roller means is longitudinally spaced from the pivot axis on the downstream side thereof.
- 5. The conveyor apparatus of claim 4 wherein there are provided at least two longitudinally spaced roller carrying assemblies supported for longitudinal adjustment on said overhead support means.
