Apparatus for reducing wrinkles in moving web

An apparatus for moving a continuous web of print media comprising:

• a roller having an axis of rotation and a diameter, the roller including a first section, a second section, and a third section, the second section being located between the first section and the third section as viewed along the axis of rotation, the roller including a profile as viewed along the axis of rotation in which the diameter of the roller in the first section and the diameter of the roller in the third section are each greater than the diameter of the roller in the second section;
• a non-rotating transport member having an operative surface proximate a first side of the web of print media, the transport member including a first section, a second section, and a third section, the second section being located between the first section and the third section, the operative surface being flat and having a non-linear profile for its trailing edge so that the edges of the web of print media pass by the trailing edge of the first and third sections of the transport member at a different time than the center of the web of print media passes by the trailing edge of the second section of the transport member;
• an air clamp located proximate to a leading surface of the transport member to control the air flow in the gap between the operative surface of the transport member and the first side of the web of print media;
• and
• the transport member being positioned along a media travel path immediately upstream relative to the roller, the first section, the second section, and the third section of the transport member corresponding to the first section, the second section, and the third section of the roller, wherein the profile of the trailing edge of the operative surface of the transport member causes the web of print media, after leaving the transport member, to have a non-linear profile in a direction perpendicular to the media travel path so that the web of print media contacts the first section and the third section of the roller prior to contacting the second section of the roller.
