Abstract: A sheet conveying device includes an aligning roller and a sheet guide. The aligning roller is configured to rotate in a forward direction along a sheet conveying direction, and stop rotation or rotate in a reverse direction to align a sheet conveyed thereto with a nip formed with the aligning roller. The sheet guide is disposed along a sheet conveyance path extending to the nip in the sheet conveying direction, and movable between a first position at which the sheet conveyance path has a first width in a thickness direction of the sheet and a second position at which the sheet conveyance path has a second width in the thickness direction less than the first width. The sheet guide is at the first position when the aligning roller stops rotation or rotates in the reverse direction and at the second position when the aligning roller rotates in the forward direction.

Following an engagement by the sheaf-conveying device, the rollers are severally rotated to evenly convey an engaged sheaf of sheets while better protecting the alignment and appearance of such sheaf.

Abstract: The present invention relates to a feed device for feeding a sorting machine for sorting flat objects and comprising at least one input feeder for the objects and pockets to which the objects are fed vertically for transport, the feed device allowing the objects to be fed one by one from the input feeder towards a vertical pocket. A conveyor module comprises at least two stop gates spaced by a distance greater than the maximum length of the objects. An accelerator module is located between the conveyor module and a vertical transfer device and comprises a downstream stop gate. The vertical ejection device is formed by an injecting module. These modules are provided with continuously operating positive entrainment devices and the stop gates control the movements of the objects in response to detectors located in the path of the objects.

Abstract: A device for straightening one edge DA of the four side edges AB, BC, CD and DA of a flexible sheet such as a crumpled bed sheet disclosed. One corner A of the sheet and a portion of the edge AB are held by a pair of laterally spaced apart, left and right holders mounted on a movable member so that the sheet is displaced on an elongated plate along the longitudinal direction thereof by the movement of the movable member. One or more laterally extending endless conveyers belts are provided on the plate to laterally move the sheet on the plate. A detector is provided to determine the direction of the movement of each of the conveyors, so that the edge DA is made in parallel with the longitudinal direction of the plate.

Abstract: An apparatus for handling sheet material articles includes a hopper which supports a stack of sheet material articles with front edge portions of the articles skewed at an acute angle to the axis of rotation of a feed drum. A separator is sequentially engageable with a corner portion of each of the sheet material articles to move the corner portion of the sheet material article away from a next succeeding sheet material article. The feed drum pulls a sheet material article from the hopper with the front edge portion of the sheet material article skewed at an acute angle to the axis of rotation of the feed drum. While a portion of the sheet material article is still in the hopper, the sheet material article moves from between the separator and the next succeeding sheet material article to expose the next succeeding sheet material article to the separator. A conveyor receives the sheet material article from the feed drum.

Abstract: A copying paper is deflected at least twice in the conveying process thereof from a paper feeding means to a photoreceptor which is disposed in the lower reaches of the conveying direction, whereby the positional state of the top edge of the copying paper is corrected at least twice. Since the extent of each deflection of the copying paper can be reduced, a habit of creasing, which has been a bad influence upon the transferring process, is not inflicted on the copying paper. The correction of the position of the top of the copying paper can be accurately carried out, whereby a clear image can be formed on the appointed position of the copying paper.

Abstract: Disclosed herein is a useful device for preventing incorrect transport of copy papers including a paper-detect member which is located in the copy-paper transport path activated by copy paper and a control member, located in advance of the copy-paper transport path and of the paper detect member, which is activated by copy papers to control the pivot motion of paper-detect member.

Abstract: A feeding device for a sheet processing machine for stream feeding to the sheet processing machine, in mutually overlapping relationship, equally thick sheets taken singly from a pile of the sheets, in combination with an alignment device for laterally aligning the sheets as they are being fed to the sheet processing machine, the feeding device includes a feed table having, together with the lateral alignment device, surfaces whereon the stream-fed sheets are supported, at least one section of the surfaces of the feed table and the lateral alignment device being disposed at a different level from that of another section thereof, at least while the sheets are being aligned, the difference in the levels being such that a preceding sheet being aligned, at the moment lies fully on a surface section of the lateral alignment device, the latter surface section being at substantially the same level as the upper surface of a leading portion of a next succeeding sheet underlying a trailing portion of the preceding shee

Abstract: An original document feeder for copying machines, for automatically positioning originals of any substance on the exposure surface, so avoiding opening and closing the original pressing cover at each change of original, and with a considerable reduction in idle times. The feeder comprises a set of friction rollers of flexible material mounted on a single shaft, these facing each other in a transverse slot so as to compel each original sheet to bend in such a manner as to exert a force against the rollers which is greater the higher the substance or rigidity of the sheets. The feeder is also provided for a device for automatically aligning the originals, and a timer system for coordinating the conveying stages of the originals with the copying machine cycle.

Abstract: A sheet-feeding arrangement for transferring sheets from supply stack to a printing machine includes a sheet-feeding table having a rear end and a front end. A pair of belt conveyors are provided in the arrangement for advancing a group of overlapped sheets from one end of the table to another. A first pair of stops for preliminary aligning of the sheets being advanced is arranged rearwardly from the front edge of the table and a second pair of stops are arranged at the front edge of the table for final aligning of the sheets being transferred. The first pair of stops are spaced from the second pair of stops in the direction of sheet advancement by a distance which is at least equal to the length of the individual sheet of the stream to prevent interference of the group of the following advancing sheets with the group of the preceding advancing sheets being moved from the preliminary steps towards the final stops.
