Apparatus for advancing and processing a flexible panel in a feed path includes a platen located proximate the feed path, the platen defining a platen surface extending in close proximity parallel to the feed path, a linear array of closely spaced fluid ports formed in the platen for receiving a pressurized fluid and directing the fluid toward the feed path in a transversely elongated fluid path, a transversely elongate chamber fixedly connected to the platen for defining a fluid chamber, the fluid ports being fluid-connected to the chamber; first, second, third and fourth roller shafts rotatably supported transversely to the feed path and having a spaced plurality of rollers thereon for contacting the panel, the first and third roller shafts contacting the panel upstream of the fluid port, the second and fourth roller shafts contacting the panel downstream of the fluid port, the rollers of the third and fourth roller shaft being located in offset overlapping relation to the rollers of the first and second roller shafts, respectively, the roller shafts being driven for advancing the panel proximate the platen, the platen having first wing portions extending between adjacent rollers of the first roller shaft for stripping the panel from the rollers of the first roller shaft, and second wing portions extending between adjacent rollers of the second roller shaft for facilitating passage of the sheet member onto the rollers of the second roller shaft, the fluid making area contact and supporting the panel in closely spaced relation to the platen.
