Paper beading apparatus for wallboard corner beads

A paper beading apparatus comprising a hopper having a body defining a chamber for holding a quantity of joint compound and a floor having a depending skirt defining a discharge opening;

• and
• a base configured for receiving said hopper and defining a cavity, a front bead opening, and a rear bead opening at opposite ends of said base and in communication with said cavity, and an inlet chute defining an inlet opening in communication with said discharge opening.

A tray for use in a paper beading apparatus for applying joint compound to a corner bead, the apparatus having a base defining a cavity and having at least two tray tracks, the tray comprising:

• at least two flanges, each said flange being generally parallel and equidistant from both a tray upper plane and a tray lower plane, said tray being reversible along a longitudinal axis of said tray and having two positions, an outside bead position wherein said tray has a generally “M”-shape when viewed on end and an inside bead position wherein said tray has a generally “W”-shape when viewed on end;
• and wherein the at least one tray track each accommodate a corresponding one of said tray flanges when said tray is in either said outside bead position or said inside bead position, the tray being disposed in said cavity.
