In the plate supplying apparatus of the present invention, various vibrations are provided to a plate secured via suction during a separating operation by causing pad rods 403 to repeat a slight ascent and a pause, and thereafter causing the pad rods 403 to make an abrupt descent, thereby reliably peeling off a slip sheet adhering to the back face of the plate. Further, vibration in the rod-up / down direction is provided to the plate during the separating operation, and the plate is not pushed hard. Thus, it is possible to prevent the plate from being damaged. A raising and lowering motor 52 is driven to lower the cassette 9. A separating operation for peeling off a slip sheet S adhering to the back face of the plate P is performed, and thereafter the plate P secured via suction is turned over and transferred.

The present invention provides a method and apparatus for separating a media combination from a stack of interleaved slip-sheets and printing plates. A media combination is separated from a media stack, including image recordable materials and a slip-sheet, is separated. The media combination is gripped and flexed in a direction, and then flexed in a second direction.

A slip sheet for use with unitized loads has a plurality of banding anchors. The banding anchors extend from an edge of the slip sheet or from a portion of the slip sheet tab. The banding anchors may be provided on one, two, three, or four edges of the slip sheet. The banding anchors may be folded up against the side of a unitized load to provide a place for packaging bands to engage the slip sheet. Portions of at least one slip tray sidewall are separated from the remaining sidewall to form flaps that may be folded down to function as tabs that help lift vehicles get under the slip tray.

A substrate manager for a substrate exposure machine is used, in one example, as a platesetter. As such, it comprises a substrate storage system, containing one or more stacks of substrates, such as plates in one implementation. A substrate picker is provided for picking substrates from the stack of substrates. The substrates are then handed to a transfer system that conveys the substrates to an imaging engine. According to the invention, a substrate inverter system is also provided. This system inverts the substrates from being imaging or emulsion side down to emulsion side up in the present implementation. This allows plates, for example, which are stored emulsion side down in cassettes to be flipped to an emulsion side up orientation, and then transferred, using the substrate transfer system to the imaging engine. This flipping process has two advantages. First, the plates can be emulsion side up during the transfer. This prevents any damage to the sensitive plate emulsions. Moreover, the plates, now in an emulsion side up configuration are in the right orientation for being installed on the outside of a drum on an external drum imaging system, as is common in many platesetters. Also, the plates are picked from the non emulsion side. Thus the system is less sensitive to emulsion formulation changes. A slip sheet capture mechanism is also provided to pass slip sheets separating the plates to a storage location.
