Anti-curl control device for an automatic dispenser of wipe materials, of the type incorporating a housing with lid, fixed end plates supporting a drum incorporating a cutting device, a material reel wound on a core having end fittings and a press roller counter-bearing upon the drum. The anti-curl device comprises a roller having a peripheral surface with protruding griping feature. The roller is freely rotatable relative to supporting plates extending from a reel-holder end plate which is flexible relative to a fixed end plate. The roller is angled obliquely relative to the material reel and comes into localized contact along its generatrix with the last turn of the reel to ensure a braking effect. The roller is linked to rotation of the drum and the reel-holder end plate is elasticly deflected to adjust in position as the reel is unwound. |
