ABSTRACT:
An envelope insert conveyor assembly includes a first pair of rotation members and a second pair of rotation members spaced apart from one another. A first conveying member is disposed around the first pair of rotation members, and a second conveying member is disposed around the second pair of rotation members, so that the conveying members rotate around the first rotation member and the second rotation member. A plurality of pusher members are fixed to each of the first conveying member and second conveying member. The pusher members each have paired sidewalls, a cross-wall connecting the paired walls, and an indented portion provided in each of the paired sidewalls. A gripping element is disposed adjacent an indented portion of one of the paired sidewalls and biased toward an interior surface of the indented portion.
