Collection procedure small fruits detached from the fruit trees or bushes, through the flexible mat (18) deployed above the ground, below the fruiting branches of said trees or bushes to be harvested, and is wound on a rotary shaft (1) coupled to an engine which assures its reenrollamiento, this canvas comprising a proximal end attached to said shaft and a distal end, characterized in that the unrolling of the mat is obtained by means of at least one and preferably a plurality of tapes (5) provided with a bendability and shape memory coiled in one or more winding drums (6) rotation axis (7A, 7B) parallel or substantially parallel to the rotation axis (1A) of the tree winding (1) of canvas (18), and whose distal end is attached to the distal end of said canvas, acquiring the unwound portion (5 ) of the belts (5) automatically, along desenr ollamiento thereof, a rectilinear shape and a property of rigidity thanks to its distal end allows to exert a thrust on the distal end of the canvas and moving said distal end towards the outside of the bearing structure (14) ensuring the deployment of said canvas.Procedimiento de recolección de frutas pequeñas desprendidas de los árboles o arbustos frutales, por medio de la lona flexible (18) desplegada por encima del suelo, debajo de las ramas fructíferas de dichos árboles o arbustos que hay que cosechar, y que se enrolla en un árbol rotativo (1) acoplado a una motorización que asegura su reenrollamiento, comprendiendo esta lona un extremo proximal fijado a dicho árbol y un extremo distal, caracterizado por que el desenrollamiento de la lona se obtiene por medio de al menos una y preferentemente una pluralidad de cintas (5) dotadas de una capacidad de flexión y de memoria de forma, enrolladas en uno o varios tambores de enrollamiento (6) de eje de rotación (7A, 7B) paralelo o sustancialmente paralelo al eje de rotación (1A) del árbol de enrollamiento (1) de la lona (18), y cuyo extremo distal está unido al extremo distal de dicha
