The invention relates to a device for controlling and regulating the pressure of a roll of material in an automatic-cutting dispenser. Each side panel of the dispenser comprises a slot that receives internally, two flanges which are disposed around said slot in lower and upper horizontal planes thereof and which are used to position and support a pivoting axel. The axel receives a flap which passes through each of the side panels, via the slot, and which extends outwards from the side panel. The rear of each side panel comprises a lug which is used to receive and fix a return means. This return means is solidly connected to the flap. In this way, when the roll-holder arm is lowered, each of the flaps is articulated and the roll is pressed continuously against the drum.
