A hot-melt tank having side walls and a bottom wall with a melt unit mounted on the bottom wall in the lower region of the tank, a melt zone. The melt unit includes a base mounted in the lower region and upwardly extending, spaced apart, parallel fins having a sloping upper end. The base does not block a material outflow port in the bottom wall of the tank, but is oriented so that the lowest portion of the sloping upper end of the fins is distal to the outflow port. A shelf, parallel to the bottom wall is positioned over the outflow port parallel to the base, intercepting the fins and secured thereto for blocking direct material inflow from the top of the tank into the outflow port. Rather, material flow is equalized in the lower region of the tank, being drawn to the outflow port from both short and long paths.

A hot-melt supply unit comprising, a heated tank means for melting solid hot melt, the tank having a lower region holding fluid melt with a material outflow port and an upper region with a solid material intake port, the tank having an upright sidewall and a bottom wall which is imperforate except for the outflow port which extends through the bottom wall at a location near the sidewall, and a melt grid means disposed in said tank for providing material flow equalization to said outflow port, the grid means having a plurality of structures providing impedance to the flow of hot melt material over short paths to the material outflow port, said structures including a plurality of upright, parallel fins, said fins having top edges which slope downwardly from a higher end to a lower end, said higher end being located adjacent to said material outflow port, said lower end being located above the imperforate portion of the bottom wall and distal to said material outflow port.
