Apparatus for registering a sheet with respect to perpendicularly related axes is disclosed. Structurally, each embodiment disclosed includes (a) a sleeve for internally accomodating a sheet, at least one point on an inner narrow wall of the sleeve being aligned in parallel with one of the axes; (b) a retractable gate located at one end of the sleeve, in one position the gate having at least one point aligned in parallel with the other of the axes; and (c) means for providing in the sleeve a fluid stream having velocity components normal to each of the axes, whereby when the gate is in said position and a sheet is placed in the sleeve, the stream moves the sheet into abutment with each of said points. |
