摘要： A sheet feeder assembly includes a self-actuating prefeed roll located upstream of a deskewing device, which can include a document sensor switch and a deskew nip roll. After a sheet has been detected at the input of the assembly, a limited slip clutch causes the prefeed nip to close. The prefeed device selectively engages the sheet based on detection of the sheet at the input and then disengages upon detection of the sheet at the deskewing device. Thus, there are no obstructions at the input that the sheet must pass before engagement by the prefeed assembly. By this, chances of misfeeding a sheet that has not been sufficiently pushed into the document feeder are greatly reduced. Moreover, the assembly has increased latitude in the positioning of the input sheet and is particularly desirable for light weight documents since no obstructions exist within the paper path. Such an assembly is very user friendly because the machine reacts to the presence of a sheet and does not rely on the operator to push the sheet completely into the feeding assembly.
摘要翻译：送纸器组件包括位于偏移设备上游的自动预送辊，其可以包括文件传感器开关和偏斜轧辊。在组件的输入端检测到纸张之后，有限滑动离合器会使预制压区关闭。预制设备基于在输入端处的片材的检测而选择性地接合片材，然后在检测到偏移校正装置上的片材时解除接合。因此，在输入端没有障碍物，片材必须在预制组件接合之前通过。由此，大大减少了未充分推入送稿器的纸张进纸错误的机会。此外，组件在输入片的定位方面增加了纬度，并且对于重量轻的文件是特别理想的，因为在纸通道内没有障碍物。这样的组件非常用户友好，因为机器对片材的存在作出反应，并且不依赖于操作者将片材完全推入进给组件。

摘要： A lateral sheet registering device for registering sheets transported along a path including a lateral registration edge positioned along the path. An apparatus is provided for driving sheets laterally and along the path so that a lateral edge of a sheet is registered along the lateral registration edge and so that sheets are transported along the path. The invention further includes a gate positioned in the path opposite said lateral registration edge for engaging an edge of a sheet to oppose rotation of such sheet in the path. The gate also is positioned to permit unimpeded transport of the lead edge of a sheet so that larger sheets are transportable within the path.
摘要翻译：一种用于记录沿着包括沿所述路径定位的横向对准边缘的路径传送的纸张的横向纸张登记装置。提供一种用于横向和沿着路径驱动片材的装置，使得片材的侧边缘沿着横向对准边缘登记，并且使得片材沿着路径传送。本发明还包括位于与所述横向对准边缘相对的路径中的门，用于接合片材的边缘以抵抗这种片材在路径中的旋转。门也被定位成允许片材的引导边缘不受阻碍地传送，使得较大的片材可在路径内运输。

摘要： Apparatus for feeding flimsy sheets of paper or the like, particularly dog-eared or curled edge original documents a sheet corner edge guiding and flattening transverse ribs system 90, 92 is provided. The sheet feeding guide baffle surface has a plurality of spaced apart and slightly vertically extending sheet-engaging ribs 90 extending thereover, divided into two opposingly diagonal sets of plural ribs 90a and 90b on the respective sides of the sheet feeding path, extending diagonally out away from one another from the centerline of the sheet separator/feeder 80 towards the respective outer edges of their respective side of the sheet feeding path. These diagonal ribs may have their upper surfaces in a common plane but can iron out towards their respective path sides the curled or folded corners of the sheet in that side of the path. The opposing baffle surface preferably has corresponding ribs 92.

摘要： A corrugating roller assembly for use in sheet handling systems for advancing sheets along a path comprising a belt supported for rotation and rollers positioned adjacent the belt to form a corrugation nip with the belt. The device further includes apparatus for allowing the belt to move from a first sheet receiving position to a sheet corrugating position so that the leading edge of a sheet advancing along the path engages the belt and is guided thereby into the corrugation nip which includes the belt. The assembly further includes apparatus for actuating the rollers to drive the sheet through the corrugation nip.
