Toshiba has developed a unique Enhanced Saddle-Stitching feature that provides amazing high capacity bookbinding handouts. This system consists of three technologies: an Enhanced Folding System, a Geared Torque Switching Mechanism and a Weight Link Sub-tray.
The Enhanced Folding System produces bookbinding handouts with a reduced thickness. Although a conventional folding system folds paper using a single folding roller, this system folds the paper twice. A conventional folding roller folds the paper first, followed by a depressing roller, which folds it once again. As a result, the thickness of the bookbinding is half that of a conventional saddle-stitch system.
The Geared Torque Switching Mechanism prevents the output from being slowed by the Enhanced Folding System process. Obviously, folding the paper twice would normally result in a lower output when compared to a conventional system. However, the Geared Torque Switching Mechanism restores output performance thanks to its ability to control the torque and speed of the roller. With this mechanism, the folding roller maintains high torque and low speed to maximize power during folding, and then switches to low torque and high speed to maximize feeding speed. As a result, this feature prevents reduced performance that would occur when compared to a more conventional model using just the Enhanced Folding System alone.
The Weight Link Sub-tray increases the output capacity of saddle-stitching. The Sub-tray automatically shifts forward in conjunction with the weight of the output. The combination of this tray with the Enhanced Folding System makes the output capacity of saddle-stitching double that of a conventional saddle-stitch finisher.
The Sub-tray gradually moves forward in conjunction with the weight of the output. The stacked output falls into the sub-tray on the way out, which then moves to the front along with the sub-tray.
