This paper feeder brings the uppermost paper sheet of a plurality of stacked paper sheets into contact with paper feed rollers and feeds out the paper sheet in a paper feeding direction by the drive thereof. Side fences for guiding both side edges of the paper sheet on a paper feeding table are provided with a pair of blowing units for blowing air to both side edges of the paper sheet, whose air quantity can be controlled independently of each other. When skewing occurs, the blowing units are controlled to blow a larger quantity of air to the paper side edge having larger friction against a lower paper sheet as compared with the quantity of air to the other paper side edge. In paper feeding, problems such as skewing, multi-feeding and idle feeding can be addressed.

The present application relates to a mail processing system and related method containing dynamic speed control which uses real time and historical system parameters to dynamically control the cycle speed of an inserting or wrapping system to optimize system efficiency, and maximize throughput and performance. A document processing system with dynamic speed control analyzes system parameters. When the operational conditions are favorable the system will increase cycle speed of one or more of the mail processing components of the system in increments until an optimal speed is reached. Likewise, if conditions are unfavorable the system will decrease cycle speed of one or more of the mail processing components of the system in increments until an optimal speed is reached.

Sheets are fed to a first, upstream trimming station to remove margin edges and optionally separate the sheets relative to the discrete page images. The sheets are then rotated 90 degrees and fed to a second, downstream trimming station that trims the right-angle edges and optionally separates the sheets into a final group of full-bleed pages, removing margins and gutter strips. The sheets are fed to a stacking assembly to be tacked in page order and any rejected, defective sheets or stacks are removed from the order.

Thereafter, upon transport of paper from the stack, a control unit causes the remaining amount detector to measure a distance y 2 for every predetermined number n of fed sheets. A remaining sheet calculation unit calculates a displacement y 1 −y 2 =Δy to the bottom of the paper stack S, and calculates the thickness of one sheet on the basis of the displacement Δy and the number n of fed sheets (t=Δy/n). The remaining sheet calculation unit divides the thickness (H−y 2 ) of the paper stack by the thickness t of one paper sheet, and calculates the number of remaining sheets m as (m=((H−y 2 )/t)+1).

A transporting device includes steering rollers, a center roller which is disposed between the steering rollers and deflection-detecting sensors that are positioned downstream from the steering rollers. When a sheet of paper has a width which is narrower than a width of a reference sheet of paper, the positional deflection of the sheet of paper is corrected by transporting the sheet of paper to a shift roller with the sheet of paper being nipped by the center roller and thrusting a forward end of the sheet of paper against a shift roller. When a sheet of paper has a width which exceeds the width of the reference sheet of paper, the positional deflection of the sheet of paper is corrected by rotating the steering rollers separately based on a detected result of the sensors with the sheet of paper being nipped by the steering rollers.
