A dual path sheet feeder is disclosed including a bypass transport loop and a main transport loop for selectively delivering sheets from a sheet feeding module to either a printer processing module or to a finishing module, wherein a movable gate situated adjacent to the bypass transport loop is provided for directing sheets along a predetermined path of travel. The movable gate is selectively positionable between a first position for directing the sheets through the main transport loop to the processing module to produce copy sheets prior to delivering the copy sheets to the finishing module and a second position for directing the sheets through the bypass transport loop to deliver insert sheets directly to the finishing module, circumventing the processing module. The dual path sheet feeder is contemplated for use in conjunction with a high speed electrostatographic printing machine for providing flexible paper supply options without the additional burden of providing supplemental dedicated sheet feeding trays.

A binding tape cartridge in which a reel of binding tape is packaged in a moisture impervious bag. The bag has an exit port through which the tape is advanced. A seal, mounted in the exit port, permits the passage of tape therethrough while maintaining the interior substantially dry. This projects the binding tape from moisture, reducing the possibility of tape delamination.

A device for selectively turning documents includes first and second drive rollers aligned along an axis which is transverse to a process direction along which documents are fed, and first and second follower rollers cooperatively peripherally aligned with the first and second drive rollers, respectively. One of the drive rollers is operated at a substantially constant peripheral velocity by a first drive which is a constant velocity motor while the other drive roller is operated at a variable peripheral velocity by a variable speed drive so that the document is turned. Thus, only a single variable speed drive, such as, for example a stepper motor or servo system, is required. The variable speed drive is driven through a variable velocity profile to control the amount of rotation of the document. Preferably the document is turned approximately 90.degree.. By placing a pair of sensors adjacent the drive rollers, the skew of the document prior to being rotated can be measured and used to determine the velocity profile for controlling the variable speed motor. After the document is rotated, the same two sensors are used to detect the skew, if any, of the trailing edge of the turned document for correction of the velocity profile used to rotate subsequent documents. An additional mechanism can be provided for shifting the connection of the constant velocity and variable speed motors between the first and second drive rollers so that a sheet can be rotated in opposite directions.

A reel on which a supply of binding tape is mounted. The reel has a hub adapted to be mounted on a shaft with at least one flange extending radially outwardly therefrom. The flange is adapted to engage a braking member to maintain the binding tape unwinding from the reel under tension as the reel rotates. The flange is mounted in a core of the reel with a pair of opposed, spaced frames extending radially outwardly from the core. The binding tape is wound about the core between the frames. A tape cleaning tool is molded integrally with the hub. The tool is molded operator removable from the hub and facilitates cleaning of the tape guides during routine maintenance.
