Hot melt adhesive supply and methods associated therewith

A method for heating and melting particulate hot melt adhesive into a liquefied form, the method comprising:

• holding a supply of the particulate hot melt adhesive in a hopper being at least partially defined by a movable wall and including an outlet coupled in fluid communication with a pathway leading to an inlet of a heated receiving device;
• moving the movable wall of the hopper to move the particulate hot melt adhesive adjacent to the movable wall toward a central interior location of the hopper;
• feeding the particulate hot melt adhesive from the outlet of the hopper through the inlet of the heated receiving device;
• heating and melting the particulate hot melt adhesive in an interior of the heated receiving device;
• directing liquefied hot melt adhesive from the interior of the heated receiving device to an outlet of the heated receiving device;
• and
• pumping the liquefied hot melt adhesive from the outlet to a hot melt adhesive dispenser.
