Abstract (en)
[origin: US5069442A] A device for the transport of recording media (3) of varying or different widths and/or thicknesses while automatically aligning the same includes a rotatably mounted and driven friction roll (1) and a plurality of rotatable pressure rollers 2a, 2b, 2c arranged in abutment with the friction roll periphery. A guide surface (6) for one of the lateral edges (3a) of the recording medium, which surface extends perpendicular to the friction roll axis (5), is associated with one end (4) of the friction roll. The pressure rollers (2a, 2b, 2c) are located off-center with respect to the length (7) of the elongated friction roll on the side or section thereof closest to the guide surface (6), while the longitudinal section (8) of the friction roll (1) which is most remote from the guide surface (6) is free of pressure rollers. The spacing (10) between the guide surface (6) and that one of the pressure rollers (2c) located most remote from the guide surface is selected so as to be at no more than one-half of the minimum of recording media that are intended for use with the transport device.
