Abstract: Apparatus and process are provided for arbitrary drawing of planar objects wherein an air current is created in a receptacle, and planar objects, having two opposing faces each having the reproduction of a picture, are introduced into the receptacle. The apparatus includes elements for capturing a planar object in an arbitrary manner, and the captured planar object can be extracted from the receptacle. The receptacle has, on its portion located toward the front, a groove having a trapezoidal section whose width decreases from its upper portion to its lower portion. The base of the groove extends, at its lower portion, beyond the outer surface of the receptacle so as to define a space which is adequate to enable passage of a planar object. The space is blocked by a retractable bar forming the base of the groove for engaging the planar object.

Abstract: A machine for the random drawing of balls being agitated by aa current of air. The machine includes a transparent receptacle in which the balls are placed, an annular space placed below and communicating with the receptacle, and a plurality of orifices defined by flaps positioned within the annular space. The flaps are capable of at least partially sealing the annular space.
