1. A bed roller machine for use in rolling a rug having a leading edge, comprising:

  • a main body havinga main bed;

    a hood having a mouth defining a cavity;

    a plurality of belts configured to move the leading edge of the rug into the cavity and up;

    a first set of fingers, each finger of the first set having a surface having a first concave cylindrical curvature, wherein the surfaces of the first set are aligned, and wherein the first set of fingers are movable as a set; and

    a second set of fingers, each finger of the second set having a surface having a second concave cylindrical curvature looser than that of the first surface, wherein the surfaces of the second set are aligned, and wherein the second set of fingers are movable as a set;

    wherein the fingers of the first and second set of fingers are interleaved and positioned in the cavity proximate the end of the plurality of belts;

    wherein the plurality of belts comprises;

    a main belt extending across the width of the first set of fingers;

    a set of secondary belts, wherein each of the belts of the set of secondary belts has an upper surface and wherein the upper surfaces of each of the secondary belts are substantially in the same plane; and

    a set of tertiary belts, wherein each of the belts of the set of tertiary belts has an upper surface and wherein the upper surfaces of each of the tertiary belts are substantially in the same plane;

    wherein the belts of the set of secondary belts and the set of tertiary belts are interleaved;

    wherein the set of secondary belts are positioned between the main belt and the set of tertiary belts;

    wherein the main belt has an upper surface that has an angle in the direction of rotation and wherein the upper surface of the main belt defines a plane;

    wherein the upper surfaces of the set of secondary belts has an angle in the direction of rotation that is more vertical the angle of the upper surface of the main belt;

    wherein the upper surfaces of the set of tertiary belts has an angle in the direction of rotation that is more vertical the angle of the upper surfaces of the set of secondary belts.
