Wiping material dispenser apparatus includes a basic housing that receives an articulated cover and a cartridge including two transverse flanges. An upper part of the flanges receives a roll of material and a lower part thereof receives a first blade-holder drum and a second return drum, the drums receiving crown wheels for the connection thereof. The return drum receives a third crown wheel that co-operates with the drum rotation actuation mechanism which includes a fixed cam. The blade-holder arm is provided with transmission means that involve the use of a mobile cam which actuates the cutting blade. The fixed and mobile cams co-operate with one another, defining the trajectory of the cutting blade. |
