A device for selective collecting of portions fashioned by cutting from a sheet arranged on a work plane (2), comprising: a removing group (4), subdivided into sections, each of which affording holes opening into a lower surface of the removing group (4), the holes being connected selectively either to an aspirating source (0) or a compressed-air source (P); activating means for moving the removing group (4); a command and control board (C) of the activating means, of the aspirating source (D) and of the compressed-air source (P), destined to connect the aspirating source (D) with at least a fraction of the holes facing the upper surface of the portion (R) selected, and the compressed-air source (P) with at least a part of the holes facing an upper surface of at least the strip (W) of the sheet (10) which delimits the outline of the selected portion (R), thereafter to cause a raising of the removing group (4) with a consequent engaging of only the portion (R). |
