A dispenser apparatus for stacked single-fold towel sheets has a rear wall, side walls, and front and rear funnel walls extending to a funnel height between bottom portions of the side walls on opposite sides of a feed slot; and a pair of shelf members projecting downwardly and inwardly from respective ones of the side walls, each shelf member having a shelf width perpendicular to the rear wall being approximately 45 percent of a housing depth between upper extremities of the funnel walls, inward extremities of the shelf members, the inward extremities being spaced above the feed slot within the funnel height and being spaced apart by a distance of not greater than approximately 90 percent of the stack width for partially supporting the sheets. Each shelf member has an upwardly and inwardly facing panel surface that forms a side angle of approximately 45 degrees with the side wall. A perimeter contour of each shelf member has a plan radius of approximately 0.5 inch at the inward extremity, diverging to the shelf width from the plan radius at a taper angle of approximately 90 degrees, the perimeter contour also having an edge profile of smooth curvature including a shelf lip radius of approximately 0.15 inch extending outwardly and downwardly from the panel surface. Another aspect of the invention provides a method for cleaning a facility having the dispenser.
