A machine that spreads out and loads flat clothing articles with an auxiliary device that deposits and feeds the flat clothing articles on a conveyer belt. The auxiliary device is located above loading end (30a) of a conveyor belt (30), extending transverse to a loading direction (D) and comprises a roof plate (13) pivotally articulated around an axis (14) transverse to loading direction (D) and providing a first position (RP1) in which the roof plate (13) is separated from the conveyor belt (30) providing a wide opening for reception of an edge of a flat clothing article (A) and a second position (RP2) in which a roof plate front end (13a) lies close to the loading end (30a) of the conveyor belt (30) allowing a controlled passage of the flat clothing article (A) on said conveyor belt (30), and driving means producing a rotation of said roof plate (13) between said first (RP1) and second (RP2) position in coordination with the operation of deposition means including nozzles (12, 15).
