Flexible sheet material roll dispensing

摘要

Dispensing flexible sheet material involves mounting at least one roll on dispensing arm means pivotally connected to a dispenser near the lower end of the chassis so that as material on the roll is depleted the concomitant diminishing diameter roll will swing down on the dispensing arm means for the roll axis to move through an arc spaced from the axis of the feed roller to wedge the roll surface firmly against the surface of the feed roller as the axis of the roll moves toward a line extending through the feed roller axis and the pivotal axis where the dispensing arm means is connected to the chassis. When the roll is essentially depleted it swings past the line and the feed roller into a discard area. Dispensing from multiple rolls in succession utilizes an initial roll mounted as above described and a reserve arm means connected to the chassis through means which permits the reserve arm means to move down vertically relative to the chassis as the initial roll is depleted to a lower position where the reserve arm means thereupon pivots relative to the chassis and the reserve roll engages with the feed roller when the essentially depleted initial roll swings into the discard area to swing through an arc similar to that which the initial roll moved through as the roll diameter diminished.
