Modified filter rod feeding trays for porous masses

1. A modified feeding tray comprising:

a rectangular bottom;

opposing first and second sidewalls coupled to corresponding first and second edges of the rectangular bottom;

a third sidewall coupled to a third edge of the rectangular bottom and extending between the first and second sidewalls;

a shelf extending from the first sidewall to the second sidewall at an intermediate location along a length of each of the first and second sidewalls and thereby defining an open compartment formed by the first and second sidewalls, the shelf, and the bottom, and a closed compartment defined by the first, second, and third sidewalls, the shelf, and the bottom;

a support within the closed compartment that operably connects to and extends from the bottom along at least a portion of a depth of the shelf; and

an elongated slot in the bottom corresponding to the support such that the support is moveably coupled to the bottom along the elongated slot using one or more mechanical fasteners.

2. The modified feeding tray of claim 1 , wherein an angle in the open compartment defined by the bottom and the shelf is less than 90° .

3. The modified feeding tray of claim 1 , wherein the shelf is repositionable along the first and second sidewalls, thereby varying a size of each of the open and closed compartments.

4. The modified feeding tray of claim 1 , wherein the shelf further comprises flanges defined at opposing ends of the shelf, the flanges extending perpendicularly from the shelf and parallel to the first and second sidewalls.

5. The modified feeding tray of claim 4 , the flanges defined at the opposing ends of the shelf are moveably coupled to the first and second sidewalls.

6. The modified feeding tray of claim 1 further comprising:

a removable gate extending between and through the first and second sidewalls in the open compartment.
