The invention has to do with a wall dispenser for rolled plastic material that is internally self-supported and without the aid of a cylindrical core component. The dispenser has a pair of rollers on which the roll rests and which are so supported in end wall slots that they may be moved toward and away from each other and generally relative to a slot in the bottom wall of the dispenser and through which the web of plastic material is dispensed. Tension springs connected to the rollers continuously urge the rollers toward one another and this transpires automatically as the material is dispensed and the weight of the roll diminishes. Provisions are made for adjusting the spring tension in the form of threaded members that are connected to the springs and vertically adjustably mounted in end wall slots of the dispenser.
