A conveying apparatus includes a conveying portion configured to convey conveyed items at a predetermined speed, a speed adjustment portion arranged midway in the conveying portion, the speed adjustment portion being configured to adjust the conveying speed of the conveyed items, a thickness detector arranged further upstream in conveying direction than the speed adjustment portion, the thickness detector being configured to detect a thickness of the conveyed items; a gap detector arranged further upstream in conveying direction than the speed adjustment portion of the conveying portion, the gap detector being configured to detect a preceding gap between a conveyed item and the conveyed item that is conveyed immediately in front of that conveyed item and a following gap between that conveyed item and the conveyed item that is conveyed immediately behind that conveyed item; and a control device configured to control the adjustment speed of the conveyed item by the speed adjustment portion. The control device is configured to decide a correction distance based on the thickness of the conveyed item detected by the thickness detector, to determine a corrected preceding gap by adding this correction distance to the preceding gap detected by the gap detector, to determine a corrected following gap by subtracting this correction distance from the following gap detected by the gap detector, and to decide the adjustment speed based on the corrected preceding gap and the corrected following gap.

According to one embodiment, a conveying apparatus includes: a conveyor configured to convey a conveyed item at a predetermined speed; a first gap detector provided midway in the conveyor, the first gap detector being configured to detect a first preceding gap between the conveyed item and a preceding conveyed item that is conveyed immediately before the conveyed item, and a following gap between the conveyed item and a following conveyed item that is conveyed immediately behind the conveyed item; at least two speed adjusters provided midway in the conveyor downstream from the first gap detector, the speed adjusters being configured to adjust a conveying speed of the conveyed item.

The present applications relates to techniques and equipment to control the alignment of cut sheets of paper that are transported in parallel in an inserting system prior to their assembly into a document and inserted into an envelope. The alignment of the parallel sheets is adjusted by commanding incremental position changes to servo drive motors used to control the position of the parallel sheets during their transport through a hold module of the inserting system.

A method for storing a series of flexible documents include: sensing a first flexible document by a sensor; thereafter, sensing a next flexible document transported toward a module and determining position information for the next flexible document; based on dimension information and a last obtained position information on the first flexible document and the next flexible document, determining a minimum distance along an axis parallel to a longitudinal axis, that would be left on transport tape, between the rear side of flexible document and the front side of the next flexible document; comparing the determined minimum distance with a predetermined minimum distance; and in response to the determined minimum distance being different from the predetermined minimum distance, adjusting the transport tape's speed between a time when the first flexible document is engaged with transport tape and when the next flexible document is engaged with transport tape inside the module.
