Abstract
An improved separator pad and spring assembly for a paper separator system is described. With this invention, securing the separator pad to the spring assembly and securing the spring assembly to a frame do not affect the characteristics of the separator pad since the separator pad is secured without being distorted by any clamping pressure. The resilient separator pad is secured to a separator spring and to a frame using shoulder screws, or equivalent fasteners, where the shoulder portions of the screws tightly secure the spring to the frame but where the heads of the screws are prevented from tightly clamping down on the resilient separator pad. This ensures that no distortion of the separator pad occurs. A feed roller (or stripper roller) is used to separate a bottommost sheet from a stack of sheets. Paper-feed springs oppose the end portions of the feed roller, while the centrally located separator pad opposes the middle portion of the feed roller.
