Drum dryer

A dryer that comprises a housing (11) that has a hot air inlet (18), a metal drum (15) mounted rotatably about its axis (X) within the housing (11), a metal gauze (17) stretched around the side surface of the drum (15) and rotationally fixed, and means (A, B) for passing a cloth (C) to be dried over the gauze (17), characterised in that the side surface of the drum (15) is formed from U-shaped profiles that each have a bottom (2) pierced with holes and two branches (3) passing radially towards the outside of the drum (15), each profile being fixed to its two neighbouring profiles by its branches (3), and wherein one of the branches (3) of each profile is larger than the other branch (3) and the gauze (17) only rests on the largest branch (3) spaced apart from the smallest branch (3).
