ABSTRACT:
A sheet feeding apparatus is arranged to feed sheets, such as bank statements, along a guideway (40) to an exit slot (16), the guideway (40) including a smooth guide surface (58) which has the configuration of part of a cylinder. Two elastomeric rolls (108) are rotatably mounted on a support (80) mounted on a drive shaft (64) whose axis lies along the center of curvature of said guide surface (58). During a sheet feeding operation, the support (80) is rotated from a position in which the rolls (108) are adjacent an entry throat (54) of the guideway (40) to a position in which the rolls (108) are adjacent the exit slot (16), the rolls (108) pressing a sheet (24') against said guide surface (58) and causing the sheet to be slidably moved along said guide surface. During this movement, gears (94, 100, 102, 104) carried by the support (80) bring about rotation of said rolls in such a direction as to increase the sheet feeding movement.
